Pressure sensor
This function is only used in combination with EXP1.
The system can use pressure sensors (transmitters) for constant duct pressure or to
measure flows.
-
Pressure sensor for pressure regulation GP1/GP2 is in a combined housing, i.e.
two sensors in the same pressure sensor. QBM68.2525
- Pressure sensors for flow regulation GF1 & GF2 are in separate housings, i.e. one
sensor in each pressure sensor, two QBM68.2500
- The pressure sensors use analog signals 0-10 V
(The sensor also has Modbus, but it is not used)
