NPA Series Pressure Sensors (MEMS)
The NPA series utilizes a high stability SenStableR piezoresistive MEMS chip in a plastic package. The sensors monitor pressure in industrial, medical, and transportation applications by generating a voltage output that is linearly proportional to the input pressure.
Characteristic：
- Pressure range from 2 inches H2O (0.5 kPa) to 30 psi (200 kPa)
- High stability and reliability with low long-term drift
- Gauge, absolute, and differential pressures
- Withstand pressures up to 60 psi
- Rugged, thermoplastic surface-mount SOIC14 package
- Dual barb, manifold, and portless designs available
- Amplified analog voltage output, digital serial (14-bit) output, digital 12C output, uncalibrated
- Total error band: ±1.5% FSO**
- Operating Temperature: -40°C to 125°C (-40 °F to 257 °F) NPA
- Compensation temperature: 0 °C to 60 °C (+32 °F to +157 °F)
- Excitation voltage: 3.3 and 5 VDC
- Customizable
- Total Error Band (TEB) includes offset, full-scale span, nonlinearity, hysteresis, non-repeatability, and all thermal effects. For 2 “H20, TEB is ±2.5% FSO
Appliance：
- Medical equipment: CPAP, medical ventilators, respirators, spirometers, anesthesia machines
