Differential Pressure
Differential pressure transmitter suitable for measuring liquid, gas or steam pressure as well as liquid level in an open or closed tank. Differential pressure transducers measure the difference between two applied pressures. These transducers generally have a high and a low pressure port. This last value is critical for a plethora of process control applications, providing insights into the ongoing efficacy of pressure vessel containers and gas flow systems. One common instance is differential pressure sensor for filter monitoring. As the filter gets clogged, the differential pressure increases.
