It indicates and transmits measurements of the three major process variables; pressure, liquid level, and temperature. MC45 transmitters offer uniform physical characteristics, same operating features and calibration procedures regardless of the measured variable.

The use of inappropriate materials can result in the leakage of corrosive process fluids and cause injury to personnel and/or damage to plant facilities. It is also possible that the instrument itself can be damaged and that fragments from the instrument can contaminate the user s process fluids.
