How to choose 3351 pressure transmitter

Introduction: Generally, the maximum measurement range of the sensor is 70% of the full range of the sensor, which is the best, that is, now to measure the pressure of 70bar, the range of the pressure transmitter should be 100bar. We need to consider the pressure of the wetted material. The medium measured by the transmitter, the material of the contact medium part of the general pressure transmitter is 316 stainless steel. If your medium is not corrosive to 316 stainless steel, then basically all pressure transmitters are suitable for you. Measurement of medium pressure. If your medium is corrosive to 316 stainless steel, then we need to use a chemical seal, which can not only measure the pressure of the medium, but also effectively prevent the medium from contacting the wetted part of the pressure transmitter. Protect the pressure transmitter and extend the life of the pressure transmitter. Range range Generally, the maximum measurement range of the sensor is 70% of the full range of the sensor, which is the best, that is, now to measure the pressure of 70bar, the range of the pressure transmitter should be 100bar. The temperature of the medium is due to the signal of the pressure transmitter It is partially converted through electronic circuits, so in general, the temperature of the measuring medium of the pressure transmitter is -30 to +100 degrees. If the temperature is too high, we generally use a condensing curve to cool the medium, which is relatively special for the manufacturer The cost of producing a high temperature pressure transmitter for you will be reduced a lot. The measuring medium is generally a relatively clean fluid, so we can directly use a standard pressure transmitter. If the medium you are measuring is easy to crystallize or viscous, we generally use an external membrane The chip or the chemical seal is used together, which will effectively prevent the medium from blocking the pressure measuring hole. The output signal of each electronic measuring meter will have accuracy errors, but because the accuracy grades marked by each country are different, for example, the accuracy of the national standards such as China and the United States is the part with the best linearity of the sensor, which is What we usually call the accuracy of the measurement range is between 10% and 90%; while the accuracy of the European standard is the worst part of linearity, which is what we usually call the measurement range from 0 to 10% and 90% to 90%. Accuracy between 100%. If the accuracy of the European standard is 1%, the accuracy of the Chinese standard is 0.5%, and the accuracy level of the pressure transmitter developed by Shanghai Yongwei Automatic Control Equipment Co., Ltd. is 0.2. Accuracy level At present, due to various acquisition needs, there are many kinds of output signals of pressure transmitters on the market, mainly 4~20mA, 0~20mA, 0~10V, 0~5V, etc., but the more commonly used is 4~ There are two types of 20mA and 0~10V. Among the output signals I mentioned above, only 4~20mA is a two-wire system (the output is a few-wire system that does not include grounding or shielding wires), and the others are three-wire systems. .
