Differential Air Pressure Sensor 100 kPa
Product Description
Note: The 1139_0B is identical to the 1139_0, except that you have the option of which size of Phidget cable to include.
The 1139 Differential Pressure Sensor is a dual ported air pressure sensor that measures the pressure difference between the two ports. It can measure pressure from 0 kPa to 100 kPa.
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. |
