The PROLINE range of junction/termination boxes are certified for continuous exposure to a wide range of  ambient temperatures and are available for use within Industrial (including hazardous), Commercial and Domestic environments. Type PR014 is for specification within general environments whilst PR015 Exe or PR020 IP66 boxes are to be specified for hazardous environments.

Operating as a "simple electrical apparatus" PROLINE digital linear sensor cable installations within hazardous environments only require environmental protection...PR020IP66 boxes... where field energy limitation is provided by appropriate "safe" area zener barrier installation.



Sufficient "knock outs" are available to allow fitting of a third gland - where required. For example, on floating roof fuel storage tanks where Proline linear sensor cable with RILSAN corrosion and abrasion resistant extrusion may be installed in a loop format around the tank rim seal, and where retractable cable may also be connected to the linear sensor cable by the junction box.


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.



A U.K. registered Company with hands-on product development, global market & application experience dating from the 1970's.

Proline equipment conforms to all NFPA 72 and EN54 standards requirements for linear detection.

Pneumatic, Digital, Analogue, Fibre Optics, Measuring Point System, Aspirating Systems...regardless of your linear detection requirement PROLINE will be happy to assist you.
