Extreme Temperature - Magnetrol International

Extreme Temperature Accessories
for use with External Level Switches
and Visual Indicators
D E S C R I P T I O N
For decades you’ve trusted Magnetrol to supply your
level instrumentation. Now, simplify the procurement
of level controls, insulation and heat tracing by letting
Magnetrol satisfy all of these requirements. Custom
fabricated insulation blankets and heat tracing options
can be manufactured and installed on any of our
instrumentation. These options may be utilized to
maintain process temperatures in external chambers
and/or to provide protection to plant personnel
against injury due to contact with extremely hot or
cold equipment. Steam tracing or electrical heat tracing
may be used with or without insulation to ensure that
the media within the external chamber is kept at a
constant elevated temperature.
