What is a SWICHGAGE
®
?
A SWICHGAGE
®
is FWMurphy’s most
renowned product. It is a rugged, highly
accurate, industrial quality gauge with a
built-in electrical switch for tripping an
alarm and/or shutdown device.
SWICHGAGE
®
models are available in
various sizes and congurations to t
a variety of applications. Models can be
electromechanical or electronic.
M u r p h y ’ s e l e c t r o m e c h a n i c a l
SWICHGAGE
®
models feature direct
actuated switching using either face
adjustable single-pole contacts or snap-
acting SPDT switches.
A unique feature is the wiping action
of the face-mounted contact(s). As the
gauge pointer meets the limit contact, a
wiping action occurs to keep the contacts
clean for positive switching.
State-of-the-art electronic models
expand the number and the type
of variables that can be monitored.
Readings and switch points are digitally
displayed keeping the user alert
to changes in operating conditions.
