Can you have a minus 20 psi gauge vacuum measurement range
Is it possible to have a vacuum pressure measurement device with a -20 to +50 psi gauge pressure range, since I’ve never seen a pressure instrument with a range greater than -15 psi?
Output signal orientation for a negative gauge pressure range
Since a negative pressure range works backwards to a positive gauge or an absolute pressure range, and that zero pressure corresponds to a full scale measurement, it has led to the use of both a forward and reverse output signal to measure suction or vacuum pressure in relation to ambient atmospheric air pressure.
Measuring negative pressure using a positive differential pressure range
How can you use a differential pressure measurement device to measure a negative pressure if it has been factory configured to measure a positive pressure range without making any adjustments to the electronics or the signal output?
What does negative and positive gauge pressure mean
You may not be aware but nearly every pressure measurement device you are using has a positive or negative gauge reference.
