Amphenol / SSI Technologies P51 Pressure MediaSensors™ are micro-machined, absolute, sealed and gage pressure sensors for harsh and benign media with superior accuracy. The series comes in a choice of three pressure sensing type conventions: absolute, vented gauge, or sealed gauge. The compact and robust sensors, with a wide variety of fittings, measure pressures from 3 PSI to 7500 PSI and are well suited for a variety of automotive, industrial and commercial applications.
Pressure sensing types:
Absolute sensors – Absolute sensors (PSIA) measure pressure relative to a sealed chamber at a perfect vacuum, which remains unchanged regardless of ambient pressure conditions. PSIA sensors are used where vacuum, or both vacuum and positive pressure measurements are needed in an application.
Gauge sensors – Gauge sensors (PSIG) measure pressure relative to ambient pressure rather than a chamber sealed at a perfect vacuum. PSIG sensors are used for lower pressure applications where measurement in a vacuum is not required or provided.
Sealed Gauge Pressure – Sealed gauge sensors (PSIS) measure pressure relative to a sealed chamber at 0 PSIG. PSIS sensors are used for higher pressure applications where measurement in a vacuum is not required or provided.
