This differential gas pressure sensor plugs into an analog input and measures pressure from 0 kPa to 50 kPa.
The 1138 Differential Pressure Sensor is a dual ported gas pressure sensor that measures the pressure difference between the two ports. It can measure pressure from 0 kPa to 50 kPa.

|This sensor is designed to measure the pressure of clean, non-condensing air. Contact with moist air (i.e, human breath), dusty air, or other gases can damage the sensor.
Take caution when connecting the pressure ports- this sensor only measures a positive pressure differential, and you could damage the sensor if you connect it in reverse. See the User Guide for connection details.
If you need a sensor with a wider measurement range, this sensor is a good choice:
If you need a sensor that can measure a negative or positive pressure difference, have a look at these differential sensors:
- 1136 - Differential Gas Pressure Sensor ±2 kPa
- 1137 - Differential Gas Pressure Sensor ±7 kPa
- 1126 - Differential Gas Pressure Sensor ±25 kPa
If you want to measure the absolute pressure of an environment, or want to use a sensor as a barometer or altimeter, these sensors will do the trick:
