Absolute Gas Pressure Sensor 20-400 kPa

Note: The 1140_1B is the same as the 1140_0, except it has a different sensor that has an upward-facing port and you have the option of which size of Phidget cable to include.

The 1140 Absolute Pressure Sensor is an air pressure sensor that measures the absolute pressure of its environment. It can measure pressures from 20 kPa to 400 kPa.

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.
