Integrated PI Controlled Differential Pressure Transmitter (0…500 Pa)

The Havkon Integrated PI Controlled Differential Pressure Transmitter is designed to measure air pressure in HVAC and building automation systems and convert the measured value directly into a control signal. The device processes the measured differential pressure using an integrated PI (Proportional–Integral) control algorithm, automatically adjusting the output signal to maintain the desired pressure setpoint.

Unlike conventional differential pressure transmitters, the Havkon PI controlled transmitter combines measurement and control functions in a single device. This allows equipment such as fan speed controllers, frequency inverters, or damper actuators to be controlled directly without the need for an external controller.

The device provides 0–10 V or 4–20 mA analog output options, ensuring compatibility with a wide range of automation systems. It delivers precise and stable pressure control, especially in applications such as constant duct pressure control, VAV systems, and filter monitoring.
