 Actuate
Electric Warning Signals Or Fuel Cut-Out. Pressures
To 1800 PSI At 520ºF
 When tank or boiler
levels reach predetermined high or low levels, the Levalarm
will actuate bells, horns or lights. EA-100 models are also
used for fuel cut-out control. The EA-100 can be
purchased with or without the body.
Operation A stainless steel float swings at the end of a pivot
rod. The rod head carries an Alnico V magnet. The
magnet attracts one leg of a U-shaped armature which is
attached to a micro-switch leaf actuator. A buoyed float
holds the switch open or closed, depending on terminals used.
As liquid levels fall, the float drops and directs the magnet
to the opposite position. A closed switch actuates alarms.
An open switch achieves fuel cut-out. Larger
