Introduction and use of pressure sensors Precautions

In daily life use and purchase pressure sensors require all it has a certain understanding, particularly when in use, if there is no understanding of good note, it is easy to cause the machine to malfunction or damage to the sensor from occurring, or is causing measurement accuracy decreased or even data is wrong. Pressure sensors, that is, when sensing the pressure, the pressure can be utilized to convert the sensor output signal, which is based on this principle manufactured piezoelectric effect, generally, piezoelectric sensors can measure only dynamic pressure can not be applied in a static measurement occasions, this is because when subjected to mechanical force generated when the role of the charge only in the loop when it has infinite input resistance, this time can be preserved. In everyday industrial practice, Engine Temp Sensor has become a very widely used sensors, many industries in order to control quality of the environment inside, have invested heavily use it. Polarization effect of the pressure sensor is based on developed. Well, this polarization effect is how it goes? Crystal, I believe we are all familiar with it. Crystals are anisotropic, not a crystal it is isotropic. When a crystal of some media in a certain direction by the action of mechanical force causing it to change the shape of, this will form a polarization effect . When the mechanical external force disappears, the crystal will return to the original uncharged state. The so-called polarization effect refers to the time when subjected to mechanical force, a number will appear inside the crystal or live effectMany industries in the use of Camshaft Positioning Sensor unit when there will be a big problem, so you understand it well before using in the course of matters that need attention. First, to avoid corrosion and temperature transmitter with having contact with the medium in order to avoid excessive damage to it; pressure guide tube mounting position preferably in the temperature fluctuations smaller occasions; in the measurement of some of the media has a high temperature, it must be connected to the condenser, it is because you want to avoid the transmitter to work when the temperature exceeds a certain limit; want to keep the catheter in the unobstructed; when used in the cold winter, if the transmitter is installed outdoors, then have a good antifreeze measures be taken, which is to prevent impulse mouth for the sake of the liquid causes freezing because its volume swell up, so easy to damage the sensor; when the user terminal, the cable should wear over waterproof connector or is it about sex tube and then sealed to tighten the nut, it is possible to prevent liquid from leaking into these things through the cables inside the housing of the transmitter. Now speaking about the measurement of liquid pressure and gas pressure precautions, we have to distinguish clearly. Measuring fluid pressure, when the pressure taps must be open in the flow line where the side surface, which is to prevent dross precipitated sake, there is installed at this time where the transmitter should prevent other liquids, shock, because Cooling Temperature Sensor excessive damage. In the measurement of gas pressure when the pressure port must be open in the top position of the pipeline process, note that this is the time with the measuring fluid pressure difference, then the transmitter must be installed in the upper part of the process piping, which is convenient have accumulated liquid may be easily injected into the flow line to go .....
