NPI Series of Media-Isolated Pressure Sensors

NovaSensor Media-Isolated Pressure Sensors - NPI Series

The NovaSensor NPI Series features a high stability SenStable® piezoresistive MEMS chip placed in a stainless steel media-isolated package. Ideal for use in hostile environments, the modular design allows for a variety of pressure port modules that are hermetically welded to the sensor header. The sensors monitor pressure in industrial, medical and transportation applications by producing a voltage output that is linearly proportional to the input pressure.

Features:

Pressure Range: 2.5 psi (17 kPa) to 5,000 psi (35,000 kPa)
High stability and reliability
Gauge, absolute and sealed gauge variants
Stainless Steel 316L package for corrosive media compatibility
HEX Diameter: 15 mm / 19 mm
Current or voltage-driven
Operating Temperature Range: -40°F to 257°F (-40°C to 125°C)
Total Error Band: ±1% FSO*
Outputs: Analog (mV) or Digital (I2C, coming soon)
Custom configurations and pressure ranges available
