Product Features

This differential air pressure sensor plugs into an analog input and measures pressure from -25 kPa to 25 kPa.
Product Description

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.

Differences from Previous Revision

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.
