Fast Pressure Controllers & Transducers

Differential Pressure Controllers and Transducers

Differential pressure instruments from Alicat have sensors that measure the difference in pressure between any two points in your process. If you leave the downstream port open to atmosphere, the differential pressure readings become equivalent to gauge pressure readings, allowing differential pressure instruments to work as gauge pressure instruments as well.

Filter Characterization with Differential Pressure Control (PC)

Characterize a filter’s flow versus pressure drop curve by fixing the differential pressure across the filter.


Valve Characterization in Martian Environments (PCD)

Cycle through several pressure differentials that are all referenced to the simulated Martian atmosphere instead of Earth’s own atmospheric pressure.
