Controllers

A controller is an important part of any control circuit. It measures the controlled variable (e.g. temperature, pressure or differential pressure) and compares it with the setpoint (W) set on the controller. Deviations (XW) are transmitted via positioning signals (Y) to the control valve, which adjusts the actual value (X) to the desired setpoint by regulating the medium.

Digitalization the Baelz way

The new digital positioners baelz 7020 and baelz 7020A make for greatly simplified operation and adjustment, offering fully automatic adaptation to a control valve, for example. The 7020 is supplied built into our actuators baelz 373-E07. The 7020A is available for our actuators baelz 373-E45, baelz 373-E66 and baelz 375-E42.

The digital positioner receives a positioning signal from a master controller and converts the signal directly. Position feedback enables automatic control according to operating pressure and actuating thrust.
