Signaline HD-S is an analogue heat sensing cable that monitors significant increases in temperature. An electronic controller connected to the cable monitors the condition of the cable to sense any change in temperature by continually measuring the electrical resistance between the metallic core and screen. If the change in temperature is sufficient the controller creates an alarm. The controller is easily adjusted for the length of cable being used. Most importantly analogue heat sensing cable is resettable.
