Pressure sensor

Pressure sensor

The pressure sensor used on the gas rig is a Keller PAA-33X with has a range of 0-100 bar. The transducer will not read below absolute but will not be damaged under such a condition and has a maximum over pressure of 200 bar.

The pressure sensor has 16 bit accuracy and performs polynomial compensation to calculate an accurate pressure taking into account the temperature.

The sensor has both analogue and digital output (RS485, which the rig uses). By using the digital bus a more accurate reading is possible.
