【 How to maintenance pressure sensor 】

The invention of the pressure sensor for our modern life and production has brought great convenience, but also improves the work efficiency and production efficiency, it became our intimate partner, automatic control technology and pipeline pressure test, or the weather forecast has a great role in promoting. How to maintain good pressure sensor and prolong its service life, in the process of use to make the data more accurate, and the stability of the data and we need to solve the problem, let us from the following several aspects to carry out the maintenance of pressure sensor: ( 1) When measuring the liquid pressure, take pressure mouth should be open in the side of the pipeline, to avoid deposit product residue. The sensor installation location should avoid the impact of the liquid ( Water hammer) In order to avoid sensor overvoltage damage. （ 2) When measuring steam or other high temperature object, need to add buffer tube ( Coil) Such as condenser, should not make the sensor operating temperature more than limit. （ 3) Should prevent dregs and the sedimentation of the intraductal TeTi contact sensor and corrosive or overheating. （ 4) Winter freeze occurs, installed in the outdoor sensor anti-freezing measures must be adopted to avoid bring pressure inside the liquid due to the icing volume expansion, leading to damage of sensors. （ 5) Guide pressure pipe shall be installed where small temperature fluctuations. （ 6) Wiring, the cable through the waterproof connector or round tube and screw down the sealing nut, such as in case of rain through the cable leakage into the transmitter inside the shell. （ 7) Measuring gas pressure, the pressure mouth should be open at the top of the process piping, and sensors should be installed in the upper process pipeline, so that the accumulated liquid injection process pipeline easily. The maintenance of pressure sensor is not only the exact data offers help to me, but also save the cost, the use of maintenance good sensors must be more durable than do not maintain sensor and would be better to use.
