Proper use and maintenance of high temperature melt YLE Crank Position Sensors

High temperature melt pressure sensor is mainly in the high temperature fluid medium pressure measurement and control, mainly used in rubber machinery, polyester and other equipment, in which an important role. Therefore, the correct use and maintenance became known as the operation staff. Damage to correct installation usually high temperature melt pressure transducers are due to its installation position inappropriate caused. If the sensor to installation in the small hole or irregular shape of Kong Zhong, Crankshaft Position Sensorsit is possible to cause vibration membrane sensor has been damaged by the impact. Select the appropriate tools to process the mounting hole, is helpful to control the installation hole size. In addition, mounting torque suitable to form a good seal. But if the installation torque is too high and is easy to cause the detachment of high temperature melt pressure sensor, in order to prevent the occurrence of this phenomenon, usually in the sensor is installed before the threaded portion with anti off compounds. In the use of such compounds, even if the installation torque sensor is very high, is also very difficult to be moved. Check the installation hole size if the installation hole size doesn't fit, high temperature melt pressure sensor in the installation process, the threaded portion of it is susceptible to wear. This will not only affect the sealing performance of equipment, but also makes the sensor can not fully play its role, and even may cause security risks. Mounting holes are suitable only to avoid the thread wear, usually by mounting hole measuring instrument to detect the mounting holes can be, in order to make the appropriate adjustments. Select the appropriate position when the installation Engine Water Temperature Sensor of high temperature melt pressure sensor is too close to the line, not the molten material may wear sensor at the top; if the high temperature melt pressure sensor is installed in too on the location, the stagnation region between the high temperature melt pressure sensor and screw rod stroke may produce melt materials, melt where possible degradation, pressure signal may also transfer distortion; if the high temperature melt pressure sensor too deeply into the machine barrel, screw may be in the rotation process touch the high temperature melt pressure sensor at the top of the damage caused by. In general, the barrel temperature melt pressure sensor can be located in front of the screen, melt pump before or die. Keep mounting hole mounting hole cleaning to keep clean and prevent frit blockage to ensure the normal operation of equipment is very important. Before being clean extruder, melt pressure sensor all should be removed from the barrel to prevent damage. In the dismantling of the sensor, the melt may flow into the mounting hole and hardened, if the melt these remains have not been removed, when installing the high temperature melt pressure sensor again it may cause the top damage. A cleaning tool package to the melt residue removal. However, the cleaning process repeated may deepen the damage of high temperature melt pressure sensor mounting holes caused by. If this happens, we should take measures to increase the high temperature melt pressure sensor in the mounting hole position. To avoid low interference in the extrusion process, the plastic raw materials, from the solid to the melt state shall have adequate "soak time". If the extruder at the start of a pre production has not yet reached operating temperature, so the high temperature melt pressure sensor and the extruder will be a certain degree of damage. In addition, if the high temperature melt pressure sensor was removed from the extrusion machine cold, material may damage caused by vibration membrane adhesion in a high temperature melt pressure sensor at the top. Therefore, before removing the high temperature melt pressure sensor, should confirm the barrel temperature is high enough, the material inside the machine barrel in softening state. Carefully clean
In the cleaning of the extruder barrel with a wire brush or special compounds, high temperature melt pressure sensor should be all removed. Because of the vibration film the two cleaning methods may cause high temperature melt pressure sensor damage. When the tube is heated, should also be high temperature melt pressure sensor is removed and a soft cloth to wipe the top wear no holes, and high temperature melt pressure sensor also need to use the drill guide sleeve clean and clean. Keep dry despite the circuit design of high temperature melt pressure sensor can withstand the harsh environment of the extrusion processing, but the majority of high temperature melt pressure sensor is not absolutely waterproof, in the humid environment is not conducive to the normal operation of. Therefore, to ensure the water cooling device of extruder barrel of water will not leak, otherwise it will cause adverse effects on the sensor. If the sensor to exposure to water or damp environment, should choose a strong special high-temperature melt pressure sensor water repellency. To prevent the pressure overload even overload design sensor measurement range of the highest can reach 50% (beyond the ratio of the maximum range), from the viewpoint of safety equipment operation should be considered to avoid risks, the best choice of the measured pressure in the high temperature melt pressure within the sensor range. In most cases, the best range of selected high temperature melt pressure sensor should be 2 times the measured pressure, so that even if the extruder operating at extremely high pressure, can also avoid the damage of high temperature melt pressure sensor.

YLE Camshaft Position Sensor Disadvantages: three parasitic capacitance effect

Initial capacitance capacitive weighing sensor is small, and the lead capacitance, electronic circuit connected with the sensor and the electronic circuit of the stray capacitance and inside the sensor plate and the surrounding conductors capacitors and other so-called YLE Auto Temperature Sensormissing large parasitic capacitance, not only reduces the sensitivity of the sensor, and the capacitance is often random change, will make the instrument work is not stability, influence the accuracy of measurement. So the cable selection, installation, connection method has strict requirements. For example, with good shielding property, its small distributed capacitance of high frequency electric wire as the lead, lead is thick and short, to ensure the instrument stray capacitance is small and stable and so on, otherwise it can not guarantee the high measurement precision.
It should be pointed out that, along with the material, technology, electronic technology, especially the rapid development of technology, the capacitance weighing sensor has been developing and YLE Engine Coolant Level Sensor constantly overcome shortcomings. The capacitance sensor is becoming a high sensitivity, high precision, low pressure sensor in dynamic, and some special measurement has a promising.

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 .
