Product Description of NPH Series Medium Pressure Sensor:
The latest techniques in micromachining have been used to ion-implant piezoresistive strain gages 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.
The user can provide standard signal conditioning circuitry to amplify the 100mV output signal. The sensor is compatible with most noncorrosive gases and dry air.
A laser-trimmed, thick-film resistor network on a hybrid ceramic substrate provides temperature compensation.
