Product Overview
The Amphenol Advanced Sensors NPH Series Solid State Medium Pressure Sensors are designed for high reliability and offer a low-cost, small-size solution for pressure measurement. Housed in a standard TO-8 package suitable for PC board mounting, these sensors are available in gauge, absolute, and differential pressure versions. They are media compatible with non-corrosive gases and dry air. Featuring SenStable processing technology for excellent output stability, these sensors provide a voltage output linearly proportional to input pressure, with typical FSO of 100 mV at 1.5 mA. They are ideal for applications in process control, pneumatic and HVAC controls, biomedical devices, and aerospace systems.
