An integrated circuit silicon sensor chip 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 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 100 mV output signal. The sensor is compatible with most non-corrosive gases and dry air.
A laser-trimmed, thick-film resistor network on a hybrid ceramic substrate provides temperature compensation.
