Pressure sensors come in three types

They are available in three pressure sensing types: absolute, vented gauge, and sealed gauge.

• 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.

P51 series pressure sensors measure between 3 PSI and 7,500 PSI in a variety of fitting options.

Applications for the P51 MediaSensor include performance automotive, compressors, generators, irrigation, and pumps. Ideal for the material handling, HVAC, industrial, automotive, and agricultural industries.
