Compatibility between measurement medium and contact material

In some measurement situations, the measuring medium is corrosive, and in such cases, materials compatible with the measuring medium or special process treatments need to be selected to ensure that the transmitter is not damaged.
8. According to the pressure interface form
Usually, threaded connections (M20 x 1.5) are used as the standard interface form.
9. According to the power supply and output signal
Usually, pressure transmitters are powered by a DC power supply, providing multiple output signal options, including 4-20mA. DC 0-5V.DC, 1-5V.DC, 0-10mA.DC, etc., can have 232 or 485 digital outputs.
10. Based on the on-site working environment and other factors
Whether there is vibration and electromagnetic interference, relevant information should be provided when selecting, so that corresponding measures can be taken. When selecting, other factors such as electrical connection methods can also be considered based on specific circumstances.
