DPSPF-LP

Differential pressure controller with display for fans. A typical application is Variable Air Volume flow or VAV control. The supply voltage is 24 VDC. The operating range is -125 to +125 Pa. It controls fan speed to maintain differential pressure or air volume flow constant at the desired set point. Air velocity control is also possible in combination with a pitot tube connection set: PSET-PTS-200. The setpoint can be adjusted via Modbus RTU communication. The sensor output controls EC fans, frequency inverters or AC fan speed controllers via 0-10 V. Another output type can be selected if necessary. The 7-segment LED display and the four LED indicators provide a clear visual indication of the transmitter status and the controlled values. The differential pressure setpoint and all other settings can be adjusted via Modbus RTU.
