The user can provide NPP Series products with signal conditioning circuitry to amplify the output signal or to maximize OEM value added. The NPP-301 Series is compatible with most non-corrosive gases and dry air. NPP-301A 0.20 in (5.1 mm) The NPP-301 Series features silicon pressure sensors in surface mount packages. An ultra-small Silicon Fusion Bonded (SFB), ultra-high stability SenStable® piezoresistive chip from NovaSensor is placed in a plastic package that exploits high volume, leadframe package technology to bring forth a low-cost sensor alternative to the OEM user. 0.06 in (1.52 mm) 0.07 in (1.8 mm) 5 -In -In NPP-301 Series schematic diagram 0.01 in (0.25 mm) 4 0.11 in (2.8 mm) 0.02 in (0.51 mm) 0.01 in (0.25 mm) NPP-301 Series package diagram NPP-301 Series Specifications Parameter Value Units Notes Parameter General Pressure Range Maximum Pressure Minimum Type Maximum Notes 100 kPa ≈15 psi Offset mV/V ±10 200 kPa ≈30 psi Full Scale Output mV 60 ±20 700 kPa ≈100 psi Linearity %FSO ±0.20 rated pressure Hysteresis and Repeatability %FSO 0.1 Thermal Coefficient of Zero %FSO/°C 0.04 4 Thermal Coefficient of Resistance %/°C 0.3 4 Thermal Coefficient of Sensitivity %FSO/°C –0.2 4 Thermal Hysteresis of Zero %FSO 0.1 5 Long-Term Stability of FSO %FSO 0.2 6 3x Electrical @ 77°F (25°C) unless otherwise stated Excitation 3.0 V Input Impedance 5,000 ±20% Ω Output Impedance 5,000 ±20% Ω 10 VDC maximum Environmental Electrostatic Damage (ESD) Class 1 Operating Temperature Range –40°F to 257°F Mechanical Units Performance Parameters (Note 2) (–40°C to 125°C) (1) Weight ≈ 0.0002 lb (0.10 g) Media Compatibility Clean, dry air and non-corrosive gases 1.
