Constant current excitation to the sensor produces a voltage output that is linearly proportional to the input pressure. 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 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. |**Parameter**
