NovaSensor OEM Pressure Sensors

NPH Series Low Pressure Sensors

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.
