Extreme Temperature Accessories FOR USE WITH EXTERNAL CHAMBER LEVEL SWITCHES AND TRANSMITTERS AND MAGNETIC LEVEL INDICATORS D E S C R I P T I O N Custom fabricated insulation blankets and heat tracing 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.
