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.
