NPH-8-030DH

NPH-8-030DH is a NPH series solid state low pressure sensor. 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, this 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 non-corrosive gases and dry air. Applications include process control, P-to-I converters, pneumatic control systems, HVAC controls, biomedical infusion pumps, sphygmomanometers, respirators, aerospace altimeters, barometers, cabin pressure sensors, computer peripherals.
