Float Switch for Tanks

The Mac3 Level Regulators are float switches that allows electrical equipment to start and stop automatically (usually pumps, but also solenoid valves, alarms, etc.) when a prefixed level has been reached.

Inside the device there is a microswitch that, depending on the level of the liquid, opens or closes the contact that powers the pump.

These Float Switches come with a 3 core cable (3x1), in either a PVC or H07RN-F sheath, which can be used for filling or emptying according to the cables that have been connected.

The Float is a double liquid proof chamber for maximum reliabilty.

The shape of the Float is designed for buoyancy and is made to ensure no edges which is particularly suitable for sewage water (along with use in water tanks etc).

The shape and switch angles (+20^o/-45^o) also means that it works well in confined spaces where there is little room for movement.

Optional Extras

Cable Type

PVC: This float switch comes with PVC Cable as standard. This is a PVC sheathed cable with PVC insulated cores equal to or exceeding EU Harmonised Code H03VV-F and British CMA Code 3183Y. Light duty, suitable for temperatures of up to +60^oc.

H07RN-F: You can upgrade the float switch cable to H07RN-F. This is a heavy duty flex with rubber insulated cores and polychloroprene or equivalent outer sheath. Increased wear resistance and flexibility compared to PVC cable, suitable for temperatures of up to +90^oc.

Counterweight

A 220g Counterweight can be added to your order to weight the cable at the desired depth/length, see options above.

Waterproof 3 Way Cable Joiner

These Waterproof TeeTube T Electrical Cable Joint (3 cable entries) can be used to fit Float Switches to Pumps where pump is submersed in the water tank.

IP68 rated so therefore (assuming fitted correctly) perfect for use underwater and in situtations where the cable joint may be submersed or areas prone to occasional flooding. Also suitable for use in areas of high condensation or humidity like for example, water tank turrets, basements and manhole chambers. If in double please consult a professional before installing this item. For more details see the Waterproof 3 Way Cable Joiner page.
