Series
Field-Repairable
Continuous Level Switches
When
your application calls for a sealed tank, or
the installation does not lend itself to easy
removal, Madison Company's C3945 and C3975
field-repairable continuous level switches should
be considered.
The
entire stem and face mount can be permanently
sealed to the vessel. Should replacement of
the reed switches become necessary, unscrewing
the
top mount and removing the entire switch assembly
can be accomplished without compromising the
vessel's interior environment.
The
ability to easily remove the C3945 and C3975
from a sealed tank allows most repairs to be
completed on-site. When compared to conventional
liquid level switches, this field-repairable
continuous level switch eliminates the need
for tank depressurization and reduces the chance
of environmental contamination.
