Float Switches
Operating Principle
A permanent magnet set in a float rises and falls on
a guide tube containing one or more magnetically operated reed switches.
Application
Suitable for almost all liquids.
Special designs are capable of liquid interface measurement.

(-196oC to 350oC)
 Pressure
Vacuum to 580 psi (4 MPa) (Higher pressure designs available).
Materials
Stainless steel, brass, titanium, Tantalum, Hastelloy,
PVC, polypropylene, PVDF, PTFE and E-CTFE coatings.
Output
Contact closure in SPST, NO or NC; or SPDT
Configurations
Flange or thread mounting. Top, bottom or side entry.
Multi-level switching with pre-set switch points. Guide tube lengths up
to 480" (40') in one piece construction. Food industry designs available.
Horizontal
Float Switches
Operating Principle
A float pivoted at one end of a short actuating arm rises
and falls with the liquid level. The other end of the actuating arm contains
a permanent magnet which operates a magnetic reed switch in the body of
the housing.
 Application
Suitable for almost all liquids.
Temperature
-320oF to 482oF (-196oC
to 250oC) [Options up to 650oF, 350oC]
Pressure
Vacuum to 350 psi (4 MPa) (Higher pressure designs available).
Materials
Stainless steel, brass, titanium, Tantalum, Hastelloy,
PVC, polypropylene, PVDF, PTFE and E-CTFE coated floats.
Output
Contact closure
Configurations
Side flange or threaded mountings.
