What is the difference between pressure gauge and differential pressure gauge?
Gauge pressure is zero-referenced against ambient air pressure, so it is equal to absolute pressure minus atmospheric pressure. Differential pressure is the difference in pressure between two points.
What is the difference between pressure and differential pressure?
Differential pressure is essentially the difference in pressure between two given points. Absolute pressure is the combined pressure of the atmosphere and the measured point. Differential pressure is more complex than Gauge or Absolute pressure as it has two variables.
What is a gauge pressure sensor?
Gauge pressure sensors provide a pressure measurement relative to the local atmospheric pressure. This is comparable to measuring a DC voltage with a voltmeter, where the voltage at the red probe is either positive or negative with respect to the point to which the black probe is connected.

What does differential pressure sensor do?
The differential pressure sensor measures the pressure drop between two points in the flow pattern and is used at two different points in the exhaust manifold. At one point it reports the charge status of the particle filter and monitors its function.
What’s the difference between gauge and differential pressure?
A 1 bar reading at high altitude (where air pressure is lower) would mean the pressure in the vessel has a lower absolute pressure than a 1 bar reading at sea-level.

What is the difference between unidirectional and bidirectional pressure sensors?
Unidirectional pressure transducers measure between zero and a positive pressure. The diaphragm of the sensor should only move in one direction and will produce a positive voltage or milliamp output.
What can a differential pressure sensor be used for?
Finally, differential pressure sensors measure the difference in pressure between two points in a system. Typically, this is because this difference can be used to measure the flow of a liquid or a gas in pipes or ducts. Alternatively, it may simply be used to detect a blockage or seized valve.
How are gauge and absolute pressure sensors similar?
Find more detail on absolute pressure sensors here. Gauge pressure sensors provide a pressure measurement relative to the local atmospheric pressure. This is comparable to measuring a DC voltage with a voltmeter, where the voltage at the red probe is either positive or negative with respect to the point to which the black probe is connected.
