NPA Surface-Mount Pressure Sensors
The NovaSensor NPA 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 ranges from 2” H2O (0.5 kPa) to 30 psi (200 kPa)
- High stability and reliability Silicon MEMS chip with low long-term drift
- Gauge, absolute and differential pressure variants
- Up to 60 psi proof pressure
- Rugged thermoplastic surface-mountable SOIC14 package
- Dual barb, manifold and no-port versions available
- Amplified Analog, Digital Serial (14-bit), Digital I2C, uncalibrated mV output options
- Total Error Band: ±1.5% FSO**
- Operating Temp: -40°C to 125°C (-40°F to 257°F)
- Compensated Temp: 0°C to 60°C (+32°F to +157°F)
