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.
