1126_1 Phidget Differential Gas Pressure Sensor, 1126


The 1126 Differential Pressure Sensor is a dual ported air pressure sensor that measures the pressure difference between the two ports. It can measure both positive and negative pressure from –25kPa to +25 kPa.


Functionally, this sensor is the same as the 1126_0. Only the size and color of the polycarbonate board that the sensor is soldered to has been changed.

Comes packaged with:


warning This sensor is designed to measure the pressure of clean, non-condensing air. While the media resistant gel does enable the sensor to be used in a wider variety of environments, the lifespan of the sensor could still be affected. For more information, check the product manual.
