This instruction provides information for mounting, electrical
connection, process connection, and calibration of SOR
®
Temperature Switches.
The SOR Temperature Switch consists of a pressure switch
with a sealed temperature sensing bulb attached directly to the
pressure port. (An optional remote temperature sensing bulb may
be connected to the pressure port with an armor-clad capillary.) The
temperature sensing system is pressure filled with a volatile fluid.
Process temperature changes cause proportional vapor pressure
changes in the temperature sensing bulb that act on the diaphragm/
piston assembly to actuate and deactuate a snap-action electrical
switching element at discrete process temperatures. The
instrument’s
behavior is
determined by vapor pressure
(105 range model fill media is inert gas).
NOTE: If you suspect that a product
is defective, contact the factory
or the SOR Representative
in your area for a return
authorization number (RMA).
This product should only be
installed by trained and
competent personnel.
