Pressure Sensor(NPH)

An integrated circuit silicon sensor is housed in a standard TO-8 electrical package that is printed circuit board mountable. The latest techniques in micromachining have been used to ion-implant piezoresistive strain gauges into a Wheatstone bridge configuration that is integrally formed on a micromachined silicon diaphragm. As with the all NovaSensor silicon sensors, the NPH Series employees 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.
