Differential pressure controllers

HPSP series are differential pressure controllers. They control differential pressure or air volume flow. Air velocity control is also possible in combination with a pitot tube. The analogue output can control EC fans, frequency inverters or AC fan speed controllers. The setpoint and all other parameters can be adjusted via Modbus RTU.

DPSP series are differential pressure controllers with LED display. They control differential pressure or air volume flow. Air velocity control is also possible in combination with a pitot tube. The display visualises the actual value. The analogue output can control EC fans, frequency inverters or AC fan speed controllers. The setpoint and all other parameters can be adjusted via Modbus RTU.

HPSA series are differential pressure controllers for damper actuators. They control differential pressure or air volume flow. Air velocity control is also possible in combination with a pitot tube. The setpoint and all other parameters can be adjusted via Modbus RTU.

DPSA series are differential pressure controllers with LED display, designed to control actuator powered dampers in function of differential pressure. The integrated PI control with anti wind-up function controls the damper position to maintain the differential pressure (Pa) constant at the requested setpoint, regardless of the demand. This makes it the ideal controller for Variable Air Volume or VAV applications. The setpoint and all parameters can be adjusted via Modbus RTU.

SPS2 series are differential pressure controllers with two setpoints. They control differential pressure or air volume flow. The analogue output can control EC fans, frequency inverters or AC fan speed controllers. One of both setpoints can be activated via the dry contact input. The requested differential pressure is kept constant, regardless of the demand.
