Choose to be aware of some parameters of pressure transmitter

1, pressure transmitter liquid material

we want to consider is the measured medium pressure transmitter. The average pressure transmitter in contact with the medium part adopts 316 stainless steel. If you have a medium have no corrosion of 316 stainless steel. So basically all the pressure transmitter of medium pressure measurement is fit for you.

if you have a corrosive medium of 316 stainless steel. Then we will use chemical seal. Such not only can measure the medium pressure. Also can effectively prevent the medium liquid part of the contact with the contact of the pressure transmitter. To protect the pressure transmitter. Birthday noodles extended the pressure transmitter.

2, scope of pressure transmitter range

general maximum range of the sensor measurement sensor is the full range of 70% is the best. That is to measure the pressure of 70 bar now. We choose the range of pressure transmitter should choose 100 bar,

3, pressure transmitter, medium temperature

because of the pressure transmitter signal is through the electronic circuit part of the conversion. So in general. The pressure transmitter measuring medium temperature is - 30 to + 100 degrees. If the temperature is too high. We usually use is condensing bending to the cooling medium. Relative manufacturers have come to make sure you produce such a high temperature resistant pressure transmitter would reduce the cost a lot.

measurement medium

usually we measure is relatively clean fluid. We adopt the standard pressure transmitter directly. If you are the measured medium is easy to be crystallized or sticky. We usually use is external diaphragm or use with chemical seal. This will effectively prevent medium block pressure measurement.

4, pressure transmitter output signal

5, pressure transmitter, precision grade

every kind of electronic meter accuracy. The precision grade marked but because each country is different. For example. China and the United States and other countries mark precision is sensor on the linearity and the best part. Also is what we usually call the measurement range of the precision of between 10% and 90%; And the target was the most bad linearity precision parts. Also is what we usually call measurements of 0 to 10% and the accuracy of between 90% and 100%. Such as the European target accuracy of 1%. The accuracy in China mark is 0, 5 %. Developed by pressure transmitter precision grade 0, 2 level.
