Differential pressure sensor and heavy duty industrial pressure sensor measurement principle and matters needing attention
Pressure sensors there are lots of, you will discover several unique classification methods. Based on distinct classification procedures may have many pressure sensors, prevalent could be divided into absolute stress sensor and pressure sensor.
Differential pressure transducer in use to be conscious of some problems Like: was measuring media not enables freezes, otherwise will injury sensor components isolation diaphragm, led to variable sent device broken, vital Shi necessary on variable sent device for temperature protection, case freezes; do not with above 36V voltage plus to variable sent device Shang, led to variable sent device damaged; in measurement steam or other high temperature media Shi, its temperature not must over variable sent device applying Shi of limit temperature, above variable sent device making use of of limit temperature have to employing thermal device; measurement steam or other high temperature media Shi, really should using thermal tube, tends to make variable sent device and pipeline even in together And use of pipe higher temperature pressure sensor transmitted to the transformer.
When water vapour is measured media, to inject the proper volume of water in the radiator pipe, direct get in touch with together with the transmitter in case of superheated steam, broken sensors do not use tough objects touching the diaphragm and lead to damage towards the diaphragm.
A separate quantity of differential stress sensors at present in use isn't a great deal, now there are numerous heavy duty industrial stress sensor can measure the absolute stress or you could measure differential stress, it really is incredibly convenient for shoppers to work with. Believe that the future will not possess a separate differential pressure sensor, differential stress and absolute pressure sensor the sensor is merged with.
