Trimod´Besta Level Switches

    Accessories | Counterflange and Test Actuator

    The simplest method of installing any  Trimod´Besta level switch of the Standard Range and the Compact Switch with a square flange, is to use our standard weld-on counterflanges. There are carbon steel (P250GH) and stainless steel (1.4404) versions in two different lengths available. The test actuator allows a periodic manual function check of the level switch in operating status. The function of the switching element (microswitch, proximity switch, pneumatic valve) and movement of the float can be tested.

    Important: For use of the counterflange on top of the tank (vertical switch) please contact us for correct application.
