NovaSensor Solid State Medium Pressure Sensors

The NPH Series available at CDI is an integrated circuit silicon sensor chip that is housed in a standard TO-8 electrical package, which is printed circuit board mountable. The NPH Series uses the latest techniques in micromachining to ion-implant piezoresistive strain gauges into a wheatstone bridge configuration that is integrally formed on a micromachined silicon diaphragm.

As with all NovaSensor silicon sensors, the NPH Series employs SenStable® processing technology, providing excellent output stability. Constant current excitation to the sensor produces a voltage output that is linearly proportional to the input pressure.

You can provide standard signal conditioning circuitry to amplify the 100 mV output signal. The sensor is compatible with most non-corrosive gases and dry air. The NPH Series provides temperature compensation using a laser-trimmed, thick-film resistor network on a hybrid ceramic substrate.
