Mounted Float Level Switches
These switches have a 2-1/2" Male tank connection. Designed
for horizontal mounting on the side of a vessel. The float
rod allows for 1-1/2" to 5" field adjustment differential
range that can be increased with the use of a longer float
rod. Standard switch ratings are SPDT and 250°F. A 400°F switch
is available. Nema 4 housing is standard. Explosionproof housings
are also available.

Side
Mounted Float Level Switches
These level switches are mounted into the vessel side at
the level where the sensor is desired. They use a low wattage
reed switch actuated by a moving magnetic field. The vessel
connection is 1" NPT male. The conduit connection for the wire
leads is 1/2"NPT male. Explosionproof versions are available.
The electrical termination is No.18 AWG polymeric lead wires
24" long.

324 Proximity Switches
Capacitive proximity switches have the ability to detect
both conductive and nonconductive objects such as water and
other liquids, plastics, wood, glass, and other materials. These
switches include a 15 or 20 turn potentiometer to adjust the
sensitivity of the switch. It also includes an LED to visually
show switching. Switches can be mounted to vessels with a Teflon®*
mounting well.
