Counterflange and test actuator

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.

Test actuator

The test actuators 2382 and 2383 can be used, if the tank is already equipped with a counterflange, type 2829.2, 2831.4, 2829.2V80 or 2831.4V80.

Important: Not for use with the Compact Switch.
