Counterflanges with and without 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. length material material length Counterflange...

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.

Float chambers Wherever it is not possible or desirable to install float switches directly onto a vessel, horizontal Trimod Besta level switches can be mounted externally in a float chamber. This type of installation allows functional checks and servicing to be carried out without interrupting operation, provided that isolation and drain valves are included in the process connections. Float chambers may be divided into 2 groups. Standard chambers PN 25 In various steel qualities and configurations with process connection acc. to DIN or ANSI. For use with the Trimod Besta level switches from the...
