PROLINE Linear Temperature Sensing

Description

The PROLINE digital linear temperature sensing cable can provide both fire prevention and fire detection at any point of risk or for area protection applications. It can be used in all environments including hazardous areas. No minimum length exposure is required as the sensor cable detects at any and all points along its length.

PROLINE’s TH temperature sensing cable is manufactured as 2 twisted and tensioned tin plated copper coated steel conductors. Around each conductor is extruded temperature sensitive material, which softens at its pre-determined temperature. At that temperature, the conductors come together to produce the required alarm signal. In the event of mechanical damage at temperatures below its alarm threshold the conductor’s extrusion is maintained resulting in an open circuit fault signal.

Sensor cables are suitable for continued use within dirty, dusty, damp environments, areas of limited access and surveillance. As a combined cable and detector the sensor cable can be installed close to the risk or at ceiling or roof height.
