Control Components TriMod Besta level switches

TriMod Besta level switches incorporate a three-module design concept comprising the switch module, the flange module and the float module. This system enables numerous 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 with IEC Ex Certification in addition to ATEX certificates are available. Standard housings offer IP65 ingress protection but IP67 and IP68 options are available for use in extreme environmental conditions.

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

The float modules and all other 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.
