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.

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

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

Designed for use in areas where flammable substances are present, 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.

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

Hang these free-floating switches in your tank for liquid-level monitoring that doesn't require installation through a tank wall.

For use in locations with flammable gases and combustible dust, this switch is UL listed and CSA certified for Class I, Divisions 1 and 2, Groups C and D; and Class II, Divisions 1 and 2, Groups E, F, and G.

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.

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.

For use in locations with flammable gases and combustible dust, this switch is UL listed and CSA certified for Class I, Divisions 1 and 2, Groups C and D; and Class II, Divisions 1 and 2, Groups E, F, and G.

Mount this switch through the top of your tank.

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

Mount these switches through an unthreaded hole in your tank wall and secure with a nut from inside the tank.

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

Easy to set up and use, these transmitters measure liquid levels using a standard float gauge.

Best for measuring liquid levels in applications where traditional mounting is difficult, these transmitters sit at the bottom of your tank.

Activate your pump in dirty water that contains sludge and sewage.
