TriMod Besta level switches

By adopting a modular concept, TriMod Besta level switches have deviated from older conventional designs and are able to deliver reliability even in extreme process applications.

TriMod Besta level switches now have IEC Ex Certification in addition to ATEX certificates, thereby enabling them to be used in Ex ed and Ex ia applications in Australia.

The switches feature a three-module design concept comprising the switch module, the flange module and the float module.

This system enables unlimited level switch combinations that will reliably manage applications requiring high-pressure components, self-checking switch elements or corrosion-resistant wetside parts. Switch modules are available with electric, electronic or pneumatic output signals.

Besta switches are shock and vibration resistant. High- and low-temperature and explosion-proof versions are available. Standard housings offer IP65 ingress protection but IP67 and IP68 options are available for use in extreme environmental conditions.

The switches are especially designed for easy installation with a hinged cover, captive screws and the self-lifting terminal clamps. For convenience of wiring, the connection diagram is shown on the inside of the hinged lid.

The float modules, like all wetted parts, are made of stainless steel, Hastelloy C or high-quality plastics. A wide range of floats is available to suit various densities and pressure ranges for almost any process condition.
