To measure negative pressure, an absolute pressure transmitter is required; consult the manufacturer for details.
What is the pressure range indicated on the transmitter’s nameplate?
We have pressure measurement points ranging from -1000 to +3000 Pa.
It’s either a differential pressure measurement or a pressure measurement point.
