This switch mounts to the outside of your tank and detects chemical level through plastic tank walls by measuring the capacitance between the switch and tank contents; it cannot be used with metal tanks.

Mount these switches from outside the tank through a threaded connection at the top or bottom of your tank.

Install these switches into an unthreaded hole at the top or bottom of your tank and secure with a nut from inside the tank.

Install these switches into a threaded connection in your tank wall from outside the tank.

Empty and fill your tank with a single device—these dual-level switches include two float switches that actuate at different levels. Mount through a threaded connection at the top of your tank.

Use the included bracket to mount these switches to the inside of your tank.

Install these switches into a threaded connection in your tank wall from outside the tank.

Install these switches through a tank wall.

These switches are CSA certified for hazardous locations.

Install these switches into an unthreaded hole at the top or bottom of your tank and secure with a nut from inside the tank.

Mount these switches from outside the tank through a threaded connection at the top or bottom of your tank.

Install these switches into a threaded connection in your tank wall from outside the tank.

Detect water level with infrared light to avoid false switch activation caused by vibration in your tank.

Install one of these relays to actuate equipment that has a higher current rating than your switch.

Measure the level of conductive liquids without drilling a hole in your tank—these switches mount to the outside of the tank and track the capacitance between them and the tank’s contents.

Mount these switches into a threaded connection at the top or bottom of your tank.

Install these switches into a threaded connection in your tank wall from outside the tank.

Detect when oil rises on water, foam forms on beer, and tanks empty, triggering pumps and valves in food and sanitary lines. These switches are 3-A and European Hygienic Engineering and Design Group (EHEDG) certified since they’re easy to keep clean.
