They are designed to operate in hostile environments and yet give the outstanding sensitivity, linearity, and hysteresis of a silicon sensor. The piezoresistive sensor chip is housed in a fluid filled cylindrical cavity and isolated from measured media by a stainless steel diaphragm and body. As with all NovaSensor silicon sensors, the NPI Series employs SenStable® processing technology, providing excellent output stability. A -Out The modular design allows for R1 a variety of pressure port modules, which are hermetically weldedD to the +In and sensor header module. Standard types A, B, H, 4 J are shown inside. R2 For compensation of temperature effects, a B complete resistor network is supplied on a hybrid +Out 5 ceramic design minimizes 3 substrate. The IsoSensor temperature errors to provide a maximum offset R5 error of 0.75% FSO over the 32°F to 158°F (0°C to C R3 2 1 70°C) compensated range. -In R4 A A -Out R1 -Out R1 D D +In +In 4 4 R6 R2 R2 B 5 3 B +Out R5 2 1 R3 +Out 5 3 R5 C -In 2 1 C R3 R7 R4 NPI-19 Series Constant Current schematic diagram R4 NPI-19 Series Constant Voltage schematic diagram -In NPI-19 Series Specifications Parameter Value Notes Pressure Range NPI 19 NPI-19VC Maximum Overpressure 0 to 100 kPa 0 to 200 kPa 0 to 700 kPa 0 to 1700 kPa 0 to 15 psi (0 to 1 bar) 0 to 30 psi (0 to 2.07 bar) 0 to 100 psi (0 to 6.89 bar) 0 to 250 psi (0 to 17.24 bar) 0 to 103.4 kPa 0 to 206.8 kPa 0 to 344.7 kPa 0 to 689.4 kPa 0 to 1379 kPa 0 to 2068 kPa 0 to 15 psi (0 to 1 bar) 0 to 30 psi (0 to 2.07 bar) 0 to 50 psi (0 to 3.44 bar) 0 to 100 psi (0 to 6.89 bar) 0 to 200 psi (0 to 14 bar) 0 to 300 psi (0 to 21 bar) 2x rated pressure 1.0 mA 10 VDC 108 Ω 4,000 Ω 4,000 Ω 5,000 Ω 5,000 Ω 1.5mA maximum 1.5 VDC maximum @50 VDC ± 20% ± 20% ± 20% Environmental Temperature Range Operating(6) Compensation Shock Life (Dynamic Pressure Cycle) -40°F to 257°F 32°F to 158°F 10 gRMs 100 g 1 x 106 Cycles (-40°C to 125°C) (0°C to 70°C) 20 to 2000 Hz 11 milliseconds Min.
