Float Level Switches

The TriMod BESTA float level switch is ideal for high and low level alarm applications including bilge level and pump control.

The instrument comprises of 3 modules; switch, flange and float. Its robust construction makes it suitable for a wide range of liquids in both marine and industrial applications.

The switch module is fitted with a micro switch and is housed in an IP65 sea water resistant die-cast aluminium enclosure.

The flange module is constructed in stainless steel. It measures 92 x 92mm and accommodates four M12 bolts on a 92mm PCD.

The float modules are determined according to function. Where difficult mounting conditions exist, the level switch can be equipped with rod extensions (G1, G2 or G3) shaped to individual requirements.

The easiest way to mount a TriMod BESTA level switch is by using the Counterflange which is available in either carbon steel or stainless steel. Test actuators are also available to permit periodic manual tests.
