Pressure transmitter range
Thread Content
Hello, experts. The range of the differential pressure transmitter is 0–3 Mpa, and its measurement range is from -20 bar to 20 bar. Is it okay to use this code? Thank you for the reply.
You mentioned that the range of the transmitter is 0~3 MPa (i.e., 0~30 bar), but the actual measurement range of the selected transmitter is -20 bar~20 bar, which is approximately -2 MPa~2 MPa. This indicates that the pressure range you actually want to measure has exceeded the transmitter’s maximum measurement range. Therefore, this code (-20bar~20bar) cannot meet your requirement of a range of 0~3MPa (30bar); you should choose a transmitter model with a range of at least 0~3MPa (for example, 0~30bar or even a wider range). .
Thank you for your reply, expert. Feel free to reply again; thanks

But 3 Mpa exceeds the upper limit of the measurement range, so that’s not possible either.
-I’ve never seen a transmitter with a pressure rating of 20BAR
-Don’t choose 20BAR; it’s not available at the moment.
