Warning

 

warning 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.
