Digital Linear Temperature Sensing

Provides “point of risk” …not the most convenient roof /ceiling height…. or “area detection” of overheat or incipient fire conditions within ALL environments….including dirty, dusty, damp and corrosive. No minimum length exposure is required in order to generate an alarm condition at a pre-determined temperature level! The combined cable and continuous detector monitors and detects adverse temperature rises at any and all points along its installed length…it’s not more sensitive at specific points!

  • FREE from RFI and /or EMI Interference
  • On site post installation direct flame testing possible without need to replace installed linear sensor cable
  • Most Economic U.K. / USA / EUROPEAN  manufactured range of linear sensor cables. Not poorer quality non European manufacture. 

Proline “TH” digital linear temperature sensing cable is manufactured as 2 twisted and tensioned tin plated copper coated steel conductors, each covered by a temperature sensitive polymer. At its rated temperature, the insulation breaks down allowing the conductors to come together to produce an alarm signal. In the event of mechanical damage at temperatures below its alarm threshold the conductors extrusion is maintained resulting in an open circuit fault /trouble signal being generated. An outer extrusion of colour coded polymer is applied around the two insulated conductors to provide a 3.5 mm external diameter linear sensing cable. For particularly high corrosive or abrasive environments a RILSAN protective extrusion may also be incorporated. Its ability to operate without adversely affecting response times / operating sensitivity has been positively tested by Underwriters Laboratories (U.L.).
Proline provides Conformity with EN54-28……..The ONLY Global standard dedicated to linear detection

Digital (LHS) & Analogue Linear Sensing

The means to locally monitor for temperature changes (rise or fall) at "point of risk" and at ANY /ALL locations along an installed length of temperature sensitive cable - regardless of environmental conditions.

Fibre Optic Linear Temperature Sensing

Line detection of temperature change and rate of rise along multi -kms lengths of small diameter fibre optic cable. It provides high performance near real time temperature Sensing and Alarm functionality with standard communication interfaces.

Proline 'Nero' Water & Moisture Detection

Rapid detection of the smallest of leaks within Industrial, Commercial Environments by a recoverable cable. Designed to provide 24 hours/day x 7 days/week continuous monitoring of areas where even the smallest of leaks can prove disastrous. Essential where undetected leakages can cause serious damage to today’s complex electrical, communications and computer networks.
