Sensor is a detection apparatus

Sensor is a detection device that can sense information being measured , and an ability to feel the information according to certain rules converted into electrical or other forms of information Cooling Temperature Sensor output required to meet the information transmission, processing, storage , display, record and control requirements. It is to achieve automatic detection and automatic control of the primary link , and the more the image is called "electric facial features ."

In the choice of the humidity sensor is easy to ignore the problem when

Humidity sensor in the selected time is always easy to overlook a lot of problems, the following specific about for everyone in choosing the humidity sensor , it is easy to overlook . Humidity sensor non- sealing , to protect the measurement accuracy and stability , should be avoided in acidic, alkaline , and an atmosphere containing organic solvents used . Also avoid the use of larger dust environments . Space to be measured as accurately reflect the humidity sensor should be placed to avoid too close or away from the wall of the dead at the air does not circulate . If the measured room is too large, it should place multiple sensors. Some of Engine Temperature Sensors on the power supply requirements are relatively high , otherwise it will affect the measurement accuracy . Mutual interference between sensors or even not work. Should be used to provide a suitable technical requirements , meet the accuracy requirements of the power supply.Crankshaft Position Sensor Replacement will require long-distance signal transmission , pay attention to the signal attenuation problem . When the transmission distance of more than 200m above , suggested the use of the frequency of the output signal humidity sensor . Because there are certain humidity sensor dispersion, either imported or domestic sensors are required to support debugging by calibration . Most of the replacement is required after re-commissioning the humidity sensor calibration, measurement accuracy for the relatively high humidity sensor is especially important.

Pressure sensor error inevitably

We choose the pressure sensor when we have to consider his overall accuracy of all pressure sensors are in fact errors exist , then the specific cause of the error , what is it , why is the inevitable errors . The offset error of the first : because the entire pressure range of the pressure sensor within the vertical offset constant , so proliferation and laser trimming correction inverter changes the offset error will be generated . Followed by the sensitivity error : error magnitude proportional to the pressure generated . If the device is more sensitive than typical values, sensitivity error will be an increasing function of pressure . If the sensitivity is lower than the typical values, then the sensitivity of the error will be a decreasing function of pressure . The cause of the error diffusion process is the change in the third linear error : This is an effect of the pressure Crankshaft Position Sensor Replacement is small initial error factors cause of this error is that the silicon physical nonlinear , but for a sensor with amplifier , also include the nonlinear amplifier . Linearity error curve can be concave curves , convex curves may be the load cell . Finally, hysteresis error : In most cases, the pressure sensor lag error is completely negligible , because silicon has a high mechanical stiffness , generally only in the case of large pressure changes considered hysteresis error . This four pressure sensor error is inevitable, we can only choose high-precision production equipment, using high technology to reduce these errors , but also in the factory calibration time for a little error , the maximum extent possible in order to reduce errors to meet customer needs .

Requirements of the light source optical fiber sensor

Fiber optic sensors, fiber-optic thin and long , when the light in which the normal transmission , and meet the measurement requirements, and ultimately, the light source has been requested , and the structure and properties of the light source also proposed certain requirements . Well, now give you some fiber sensors What are the requirements for light bars . The first is due to limited fiber optic sensor structure , requiring light small, easy and fiber-coupled light source have enough brightness to increase Motor Sensors output optical power. Wavelength of the light emitted by the light source should be suitable to reduce the light transmission in the fiber of the energy loss. Second light work requires good stability, low noise, can be long-term work continued at room temperature , the light source to be easy to maintain , easy to use .

Shake the load sensor installation

Familiar with the load cell knows that the load cell is generally relatively stable installation . However, in real applications but there are some problems that some of the environmental sensor is installed is not stable . Some may appear to shake shake and some lists of questions , this time weighing stability of the sensor is quite important, but also the case for the vibration sensitivity of the sensor linear relationship may be partially affected . Said load Shaft Position Sensor  can be installed under shock conditions is relatively cumbersome and difficult to operate , the output signal error is inevitable because of the force load cell originally converted into a voltage or current time of an apparatus , the external force changes the direct affect the output of the letter . Only this time the sensor's error problem of the performance characteristics of the sensor itself , but also a very important problem is to install the issue. Vibration environment with Engine Temperature Sensors must have a high stability than general , need to select the environmental impact by the external sensors , of course, be noted that the terminals of the load cell must have good fixability and prevent in the vibration environment caused by poor contact force change and other issues . Fixity in understanding terminals , we should first be noted that the entire load cell fixity . Of course, we say that the external vibration is relatively fixed during fixed , only the fixing of the sensor in order to maintain the stability of the data signal transmission . For different environments to select a different installation methods , technician needs before purchasing platform stability test installation , and then communicate and manufacturers , recommended by the manufacturers choice of what kind of load cells and how to install the sensor in order to greatly reduce the sensor's error

Gas temperature and the sensor itself will happen at different temperatures

Gas temperature and the sensor itself will happen at different temperatures : the temperature sensor itself determines the minimum display current, while the temperature of the sample gas to be measured shall have a certain impact . Gas molecules through the pores into the sensing electrode determines the rate sensors. If the temperature of the gas diffusion through the pores of the gas inside the sensor at different temperatures, the sensitivity of Engine Water Temperature Sensor may have been affected . Set before the device has completed , there may be slight drift or instantaneous current changes. The gas sensor is exposed to the target gas can be continued : gas sensor to monitor the target gas intermittently , generally not suitable for continuous monitoring purposes , especially with regard to high gas concentrations , high humidity or high temperatures . In order to achieve the purpose of continuous monitoring , sometimes with two ( or three ) sensors recycling method so that Crank Shaft Position Sensor is at most only half of the time exposed to the gas , the other half can be restored in the fresh air . Gas sensors will make full use of micromechanical and microelectronic technology, computer technology , signal processing technology, sensor technology , fault diagnosis technology, intelligent technology and other subjects on the basis of integrated technology to develop. Developed to simultaneously monitor multiple gases automatic digital smart gas sensors will be an important research direction in the field

Gas sensor 3 different sources in case of failure analysis

Gas sensor , a gas volume fraction to a corresponding electrical signal into the converter. We use gas sensor, will inevitably encounter some problems, such as gas sensors need to use long after recalibration ? And in the use of the process will produce different fault , which we need this in the analysis. How long is required after the gas Crankshaft Sensor Replacement recalibration : The initial calibration and re- calibration of the length of the interval depends on many factors , often including sensor temperature , humidity, pressure , which is exposed to the gas , and the duration of exposure to the gas . But most products can provide a very stable signal over an extended period , the use of gas sensor requires only periodic calibration , such as once a year. Such as sensors or for demanding security applications , the calibration may be necessary for some relatively frequent .
