Fantech Constant Pressure Control for EC-Motor Fans

The sensor control module for differential pressure and volume flow measures and indicates the pressure or, optionally, the volume flow in a ventilation system. The calculation of the volume flow is performed by entering the K-factor of the application. Depending on the desired setpoint value and control range, the sensor control module generates 0-10 V to control the EC fan or e.g., a frequency inverter. The sensor control module is supplied by the fan or frequency inverter which it controls, e.g., with 10-24 V DC.
