1139_0 Differential Gas Pressure Sensor 100 kPa
This differential air pressure sensor plugs into an Analog Input or VINT Hub port and measures pressure from 0 kPa to 100 kPa.
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.
