NovaSensor has joined other GE high-technology sensing businesses under a new name GE Industrial, Sensing. g0.25 in (6.35 mm) 0.003 0.344 in (8.74 mm) maximum GE Sensing +In (Red) NPI-12 Series Specifications -Out (White) +Out (White) Description The NPI-12 Series of solid state, media isolated pressure -In (White) sensors are designed to provide a cost effective solution NPI-12 Series schematic diagram for applications that detect tube blockages and pump performance. The NPI-12 Series is intended to mount 3.3 in (83.8 mm) 0.10 adjacent to flexible tubing to sense tube expansion. Cleanliness is assured with the NPI-12 Series stainless +In (Red) steel finish. +Out (White) -Out (White) -In (White) The NPI-12 Series incorporates state-of-the-art IsoSensor technology, which gives the OEM user the best in price 0.25 in (6.35 mm) 0.003 and performance. They are designed to operate in hostile 0.244 in (6.197 mm) 0.003 environments while providing outstanding sensitivity, 0.07 in (1.78 mm) 0.003 linearity and hysteresis. The piezoresistive sensor chip is 0.062 in (1.57 mm) housed in a fluid filled cavity and isolated from the measured media by a stainless steel diaphragm and body. As with all NovaSensor silicon sensors, the NPI-12 0.008 in (0.20 mm) maximum Series employs SenStable processing technology, which Weld 0.477 in (See note 1) provides excellent output stability. (12.11 mm) 0.003 The NPI-12 Series offers many features with superior 0.497 in (12.62 mm) 0.003 performance. The pressure sensitivity is calibrated at NPI-12 Series dimensions 0.200.01 mV/V/psi. The combined errors of linearity, pressure hysteresis, repeatability and temperature are less than 4 %FSO. The maximum overpressure is 50 psi Parameter Value Units Notes (3.44 bar). A five volt excitation is needed to supply power General Pressure Range 15 psig to the device. The operating temperature range for the Maximum Overpressure 50 psig rated pressure NPI-12 Series is 50F to 104F (10C to 40C), while the Environmental storage temperature is -40F to 158F (40C to 70C). Temperature Range Operating 50 to 104 F (10C to 40C) Electrical connection is accomplished with a 4 pin Storage 40 to 158 (Dry) F (-40C to 70C) connector that accepts standard 0.025 in (0.64 mm) Mechanical square posts on 0.100 in (2.54 mm) centers. A red wireWeight 0.01 lb(5 g) Media Compatibility 316L stainless steel allows for easy recognition of connector orientation.
