How to choose a single color infrared temperature sensor

Infrared temperature sensor , a temperature sensor , and control of the temperature- monitoring device production process or the critical power . Infrared temperature sensor according to the principles can be divided into monochromatic color YLE Engine Coolant Temp Sensor and the temperature sensor . This difference between the two and the selection determines the different performance characteristics .For monochrome temperature sensor during temperature measurement, the measured target area should be full field of view sensor. Recommended target size measured more than 50% the size of the field of view as well. If the target size is smaller than the field of view , the background radiation energy as the sound operator will enter the branch interference temperature sensor readings , causing YLE Crankshaft Positioning Sensor. Conversely , if the target is larger than the field of view thermometer , thermometer would not be out of context affect the measurement area .The ratio of the color temperature sensor is composed of two separate wavelength band of the radiation energy is determined . Therefore, when the measured object are small, full field , measuring the presence of smoke passage , dust barrier attenuation of radiation energy , the measurement results will not be affected , even in some attenuation of 95 % of the cases , still ensure temperature measurement accuracy requirements.For a small target , and is among the target motion or vibration ; sometimes within the field of exercise, or the target portion may be moved out of the field , in this condition , the temperature sensor using the color choice . If this is not under the direct aim and objectives between the thermometer , measuring channel bend , narrow , blocked , etc., two-color fiber optic temperature sensor is the best choice . This is due to its small diameter , flexible , can be bent, folded channel blocking and transmission optical radiation energy , and therefore is difficult to be measured close to the electromagnetic field near the target or harsh conditions .In determining the attachment , should be as standardized services required to reduce installation costs. Survey smoke , dust or other particles to reduce energy signal measurements , color temperature sensor is the best choice . In noise , electromagnetic , vibration, or near ambient conditions is difficult , or other adverse conditions , the optical fiber temperature sensor is the best color .

Low will affect the long-term high-grade automotive oxygen sensor sensitivity

Sensor There are many types of internal use , wherein the oxygen sensor in the engine that is essential. Recently, some users say the car will affect the long-term high-grade low- oxygen sensor sensitivity , that really so? Xiaobian to tell you the answer .The formation of coke and coke formation on the general impact of the engine for three reasons : First, the use of " low- grade " bad driving habits. There prolonged idling and low-speed driving. On the other hand is mainly the use of the purity and quality of gasoline . Carbon impact is mainly reflected in the engine cold start problems , less than the required cold idle speed, idle severe cold will turn off after the hot car idling low . Also lead to decreased engine power , poor acceleration , fuel consumption increases ; engine exhaust emission deterioration , it also shortens the spark plugs, oxygen YLE Engine Position Sensor, catalytic ternary is life. The most important is the carbon of the engine will cause jamming of the piston ring , piston ring sealing performance , resulting in increased oil consumption , resulting in engine burning oil , shortening the life of the engine . Remove carbon deposits and effects of regular cleaning methods are generally divided into three steps , fuel injectors and intake cleaning can remove part of the coke, and be able to soften deep coke, oil tank can add agent to sustained cleaning carbon recovery nozzle atomization , keeping the oil flow, restore the power of the engine, eliminating the engine cold start problems , unstable idle , such as failure to improve fuel economy and extend spark plugs, oxygen YLE Crankshaft Position Sensor Replacement, catalytic converters , engine life. When Wei -off power enhancer plus 5% of the amount of oil available in the market mix , polymer nanospheres hundreds of millions in the role of " Brownian motion " , the heat will be more than ten meters per second velocity, so that it can be in the lubricant evenly, stable distributions. Meanwhile , using the kinetic energy given to the thermal motion of the continuous passage of oil and mechanical impact surface of the deposited abrasive, carbon and grease produced potent " physical washing " effect, restored or ensure clean working environment of the engine , eliminating the impurities possibility of causing engine failure. Since a huge amount of polymer nanoparticles uniformly distributed in the lubricant to add gravel becoming similar to cement concrete strength enhancement principle , making significantly improve the strength of the oil film , oil seal , seismic performance greatly enhanced. Because of poor air tightness engine , the larger the gap caused by channeling oil under channeling combustion residue , corrosion , oil aging failures can quickly eliminate or alleviate . In addition, due to increased cylinder pressure , exhaust valve scavenging momentum greatly improved , making the exhaust pipe carbon is strongly purge , exhaust pipes become very clean. Measures to prevent carbon generated models to choose the grade of gasoline according to the manufacturer 's instruction manual , but it should be noted that the label represents gasoline octane gasoline , reflecting the gasoline antiknock quality of gasoline and gasoline can not label On the phase problem and recommended to the regular reputable gas station , due to crude oil and refinery process , coupled with the sale of commercial gasoline market is not a high -quality gasoline, gasoline components containing sulfur , phosphorus, especially in the higher olefin content and oxidation stability is poor, olefin oxidation condensation will form a gelatinous when the engine of internal combustion work, and the engine crankcase exhaust and intake of dust particles in the collection , the throttle body , intake manifold , etc. to form coke. Also driving habits and conditions of use is also very important , bad driving habits " low grade " driving causing incomplete combustion gas mixture easily generated carbon ; avoid prolonged engine idling , the vehicle for a long time at low speeds , should always run a run high-speed , high-speed driving can make mixed combustion , improved fuel economy and can reduce coke formation, to restore the sensitivity of the oxygen sensor , clean the spark plug electrodes between carbon and catalytic converters surface.

Proximity Sensor Selection Tips

Ground sensor applications has been particularly broad application of its model , different functions are also different, its main feature is the small size, easy to install, inexpensive , how do we determine what you want to do a proximity sensor to specifically look . First , the proximity sensor according to the measured object by selecting the material . If the required sensing distance is shorter , inductive proximity sensors can be easily and efficiently detect any type of metal objects. If the distance , you can use the photoelectric proximity sensors. If the sensor is very far away , it is best to use on the radio or reflective photoelectric sensors. Secondly, since the capacitive proximity sensor can detect the material is very much, but the sensing distance corresponding to recently, and inductive Camshaft Positioning Sensor similar . If you use a capacitive proximity sensor , then the volume of the object to be detected can not be too small to meet the minimum sensing object of the sensor volume requirements. Ultrasound and Engine Temperature Sensor can detect a wide range of materials , and detection distance is relatively long . However, in the detection of objectswith irregular surfaces may cause problems . Finally , and more for the Motor Temperature Sensor selection criteria , or to rely on the characteristics of the measured object , and to take into account the sensor installation and environmental factors . Once all these issues are clear , then it can be selected from a number of sensors a suitable type. Understanding of the proximity sensor selection step that we can more quickly and accurately selected their own
needs sensors. Of course, this is just a selection procedure , to treat specific problems but also specific coping .

How to correctly judge the photoelectric sensor output no signal

Photoelectric sensor is a photoelectric sensor element as a sensing element , widely used in the automation field . Photoelectric sensors for material handling, error detection , process manufacturing automation, object detection can also be used over long distances or fault is detected. Photoelectric sensors detect the distance of the object has a unique advantage , but in the specific use of the environment, there will be some technical problems , which we need methodical technical judgment. In the application of photoelectric sensors to detect objects in the distance , a lot of users will encounter problems when using photoelectric sensors to detect objects is no output signal after , making it impossible for subsequent data analysis. Most people see no signal sensor output may often be some wrong judgment , such as some people on the direct determination of Shaft Position Sensor bad reason. But the reason is not all like that, photoelectric sensor detects an object after no output , there may be many reasons , we need to do it step by step investigation . The first thing to consider is wiring or configuration problems . For beam photoelectric sensor must be cast by the light unit and a light unit used in combination with both ends requires power ; while retroreflective Engine Temperature Sensor probe and must be retroreflective sheeting used in combination ; same time, the user must provide a stable power supply to the sensor , if it is DC power supply , you must confirm the positive and negative , should the positive and negative connection error will cause the output signal is not . The reason analysis is to consider Camshaft Position Sensor itself , we also need to consider the problem is to detect the location of objects , if the detected object is not in the detection area , so that the detection is futile. Test object must be detected in the sensor area , that is, can sense the optical range. Secondly, we must consider the optical axis of the sensor there is no alignment problem , on the radio type of light-emitting portion and a light receiving unit must be aligned with the optical axis , the corresponding portion of the retroreflective type sensor must be aligned with the optical axis and the reflector . The same should also consider whether the detected object is the standard sensing object or minimum standard sensing object , object detection can not detect an object less than the minimum standard , thus avoiding lead shot , reflective not well detect transparent objects , like a reflection on detecting the color of objects is required, the deeper the color , the more recent detection distance . If the above conditions can be excluded to make it clear , we need to do is to detect environmental disturbances . Such as light intensity can not exceed the rated range ; if there is dust environment of the scene , we need our regular cleaning optical sensor probe surface ; or more sensors close fitting , mutual interference ; there is a relatively large impact that electrical interference , if surrounded power equipment , interference must have the appropriate anti-jamming measures . If you have done the above one by one investigation , these factors can be explicitly excluded or no signal output , it is recommended to return factory testing to determine .

The method of pressure sensors to achieve impact

Pressure sensors used in many bad environment , some of the bad environment may be more severe , such as pressure sensors need to measure the impact pressure , the measured impact pressure generally requires relatively high pressure sensor performance , we usually have several ways to measure the impact type pressure . The first method is to change the pressure transmitter chip , not an ordinary ceramic cores or diffused silicon core , but with strain gages , strain gauges is a strain on the DUT will be converted into an electrical signal of change sensitive device. It is a piezoresistive Camshaft Position Sensor of the main components . Resistance strain gauge is the most widely used metal resistance strain gauges and semiconductor strain gauges two kinds . Metal resistance strain gauges have filamentous strain gauge and the metal foil strain gages two kinds . The strain gauge is usually via a special adhesive binder tight mechanical strain is generated on the substrate , the force occurs when the substrate stress , the resistance strain gauge is generated with deformation, the resistance strain gauge is changed , so that the the voltage across the resistor changes . The strain gauge force generated when the change in resistance is usually small , it typically are composed of strain gage bridge , and through subsequent instrumentation amplifier is amplified , and then transmitted to the processing circuit . Strain gauge Auto Temperature Sensoris generally shock and impact resistance is better, but this sensor accuracy with their manufacturers . The second method is to use an ordinary ceramic Coolant Temperature Sensor or pressure sensor to measure diffusion silicon , but not be measured directly , but with the addition of a buffer tube , which also can measure the impact pressure . This method is economical , easy to install , so the application is very extensive. Regardless of the method is to measure the impact pressure sensor core body protection is not strong pressure washed out . Which method based on the specific use now have a bad environment and customer choice .

In the course of the humidity sensor has several issues deserve attention

In the course of the humidity sensor has the :Select the measurement range and weight, temperature , the choice of the humidity sensor must first determine the range of measurement. In addition to weather , research departments, to engage in temperature and humidity monitoring in general do not need all wet process (0-100% RH) measurements. In today's information age , Shaft Position Sensor technology and computer technology , automatic control technology closely integrated with . The purpose is to control measurement , measurement range and control of the use of collectively . Of course, do not need to engage in monitoring and control system applications are concerned, directly select universal moisture meter on it. Select the same measurement accuracy and measurement range , measurement accuracy of the sensor with the most important indicators. Each increase - percentage points. It is for the sensor to a higher level , or even on the next level . To achieve different accuracy because its manufacturing costs vary widely , the price is also very different. For example imports an inexpensive Engine Coolant Temperature Sensor only a few dollars, and one for the entire wet process of calibration and humidity sensors to a few hundred dollars , a difference of nearly a hundred times . Therefore, the user must be tailored , not the blind pursuit of "high, fine, sharp ." Manufacturers often give its humidity sensor segmentation accuracy . In case of low humidity segment ( 0 a 80% RH) was ± 2% RH, and the humidity segment (80-100% RH) was ± 4% RH. And this accuracy is at a specified temperature (such as 25 ℃) value. If used at different temperatures andCar Temperature Sensor. Its indication should also consider the impact of temperature drift . Is known , the relative humidity is a function of temperature , temperature seriously affecting the relative humidity within the specified space . Each change of temperature 0.1 ℃. Will generate 0.5% RH humidity change (error ) . If it is difficult to do using the occasion thermostat , the proposed high measuring precision is inappropriate. Because humidity variations with temperature drift suddenly uncertain , then talk about measuring precision will be moot . So first of all to control humidity temperature control is good , this is the large number of applications are often temperature and humidity - sensor integration and not simply because of the humidity sensor . In most cases, if there is no precise temperature control means , or a non- sealed space is measured , ± 5% RH of accuracy is sufficient . For applications requiring precise control of temperature and humidity of the local space , or need to keep track of changes in humidity recording of the occasion, and then use ± 3% RH. Above precision humidity sensor . And this corresponds to the temperature sensor. Its measurement accuracy ± 0.3 ℃ above shall be sufficient , at least ± 0.5 ℃ for . The accuracy better than ± 2% RH sensor calibration requirements but even the standard humidity generator is also difficult to do , not to mention the sensor itself .
