Immersion Heaters Temperature Controller System Overheat Temperature Protector
Over Heating Temperature Protectors for Electric Immersion Heaters
Temperature protection devices are used to protect internal circuits or devices from over heating. The resistance of Heating elements thermistorsrises rapidly when a certain temperature isexceeded, thus stopping the flow of current. This characteristic is self-regulating: Once the Temperature cools down, it permits the current to flow again.
1, 2, and 3 Series Protectors
Thermal overload protection
The Protector 1 overtemperature control system utilizes a heat sensitive fuse to detect overheat conditions. The protector, placed inside a thermowell, positioned in contact with the heater sheath, will cut power to the heater in the event of low liquid The Protector 2 and Protector 3 systems provide the same reliable overtemperature protection as Protector 1
However, the control systems feature a heat sensing thermostat. If the liquid level drops and the heater reaches a preset overheat heater can quickly be made operational by pushing the reset button on the control to restore power. Protector 3 is designed for flexible lead or high temperature fluoropolymer (PTFE) heater applications only.
