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.
