Identify the “high” and “low” ports on this pneumatic differential pressure transmitter, and explain your reasoning:
Pneumatic DP Transmitter
Port “A” is the “high” pressure port on this transmitter, and port “B” is the “low” pressure port.
Remember: an increasing pressure applied to the “high” port causes an increasing signal out of the transmitter.
Conversely, an increasing pressure applied to the “low” port causes a decreasing signal out of the transmitter.
Note: These are very old models and obsolete now.
