NPI-12 Stainless Steel Media Isolated Sensor

Supplier: GE Sensing

The NPI-12 series of solid state, media isolated pressure sensors are designed to provide a cost effective solution for applications that detect tube blockages and pump performance.


The NPI-12 is intended to mount adjacent to flexible tubing to sense tube expansion. Cleanliness is assured with the NPI-12's stainless steel finish.

Product Description of NPI-12 Stainless Steel Media Isolated Sensor:

The NPI-12 Incorporates state-of-the-art IsoSensor technology, which gives the OEM user the best in price and performance. They are designed to operate in hostile environments while providing outstanding sensitivity, linearity and hysteresis.

The piezoresistive sensor chip is housed in a fluidfilled cavity and isolated from the measured media by a stainless steel diaphragm and body. As with all on NovaSensor® silicon sensors, the NPI-12 employs SenStable® processing technology, which provides excellent output stability.

The NPI-12 offers many features with superior performance. The pressure sensitivity is calibrated at 0.20±0.01 mV/V/psi. The combined errors of linearity, pressure hysteresis, repeatability and temperature are less than ±4 %FSO. The maximum overpressure is 50 psig.

A five volt excitation is needed to supply power to the device. The operating temperature range for the NPI-12 is +10°C to +40°C, while the storage temperature is –40°C to +70°C.

Electrical connection is accomplished with a 4 pin connector that accepts standard .025 inch square posts on .100 inch centers. A red wire allows for easy recognition of connector orientation.
