Exclusive Watt-Flex Split Sheath Cartridge Heaters Option

Watt-Flex split-sheath cartridge heaters can be manufactured with a groove along the exterior of the cartridge to accommodate a needle-type thermocouple for more accurate temperature sensing and control.

Watt-Flex Split Sheath Cartridge Heaters

Watt-Flex external thermocouples out perform internal monitors used in conventional heaters. With Watt-Flex Cartridge Heater, you can:

  • Measure temperature at the precise point of heat transfer. Unlike conventional heaters with internal thermocouples that measure internal heater coil temperature, Watt-Flex external thermocouples measure more precisely at the point where heat transfers from the heater to the host metal.
  • Monitor temperature at any point along the heater. Hampton Controls Watt-Flex heaters give you the flexibility to monitor heat at any point along the heater, instead of at pre-defined fixed points with internal monitors in conventional heaters.
  • Replace heater or thermocouple independently. With Watt-Flex external thermocouples, you can replace either the heater or the thermocouple independently, without having to replace an operational component as with conventional heater designs.
