Precision proportional pressure regulators of the REGTRONIC series are used to control fluctuating pressures as a function of a specified setpoint. The remote control can be carried out via a cable with M12x1 plug as voltage or current input or via an RS232 interface. Control is also possible directly on the controller using the keys and the display. The actual pressure value and further information as well as diagnostics are visible on a display at any time. This display, the LED indicators and operating buttons are placed on the same side of the device. The software for programming is comprehensive, simple and self-explanatory. The pressure control is done in a closed system with a precision electronic sensor for measuring the secondary pressure, a controller for comparison with the set point and two miniature solenoid valves for setting the desired pressure set point.
