Specifying Mica Band Heaters
Important parameters to consider when specifying band heaters are: maximum operating or sheath temperature, AC voltage required, and watts. Electrical power is measured in watts. Maximum operating temperature is the maximum temperature that the sheath covering the heater may reach. The maximum sheath temperature does not represent the maximum temperature that a heated substance may reach. AC voltage required represents the minimum AC Voltage required to operate the heater. Watts represents the maximum wattage available from the heater. Important dimensions to consider for band heaters are the inside diameter of the band, the width of the band and the thickness of the band. The heater inside diameter should be the same size as the outside diameter of the heater cylinder to be heated.
