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.
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.
