P Series Pressure Transducer
Provide real-time measurements of absolute, gauge, or differential pressure
Measure the absolute pressure (referenced to vacuum) or gauge pressure (referenced to local barometric pressure) of gases or liquids at any point in your process. The in-line design allows you to quantify the pressure of a flowing process without introducing a dead-ended obstruction to your system. Or, you can measure the differential pressure between any two points in your process. The two process ports connect to opposite sides of the differential pressure sensor; positive readings denote higher pressure at the left (upstream) process port, and negative readings denote higher pressure at the right (downstream) port. This differential pressure transducer can also double as a dead-ended gauge pressure transducer if you leave the downstream port open to atmosphere.
Both absolute and gauge transducers as well as differential transducers are available with a rechargeable battery to make your transducer easily portable (PB series). Keep pressure validation processes as short as possible with this always-ready portable pressure transducer.
As well, instruments in the standard P and PB series are available with an optional “S” configuration (PS or PBS) for use with liquids and corrosive gases. In this configuration, the flow body and sensors have been upgraded to 316L stainless steel and the elaastomers to FFKM.
Alicat’s P series of pressure transducers can be custom built with your choice of options. Choose your communications protocol, display, process connections, elastomers, and calibration. Need further customization? Contact us and we’d be happy to help you build the instrument you need.
Each standard pressure transducer comes with a NIST-traceable calibration certificate and an Alicat operating manual. Power supply sold separately. Portable pressure transducers come complete with a micro-USB charging cable and AC wall adapter, NIST-traceable calibration certificate, and an Alicat operating manual.
