GWG 12 K/1 45100 GWG 12-K/1 360mm gelb Images 1 Back GWG 12 K/1 | 45100 Grenzwertgeber für Behälter in Innenräumen in-stock items Documents Benefits design as per EN 13616metallised sleeve for permanent operation even with biopetroleum/biodieseluniversal use due to variable height adjustmentimpact-resistant, shock-resistant and deformation-resistant GWG level sensor connection fitting (type 905 yellow)the right version for each applicationProofed Barrier (odour-tight)materials resistant to biofuel and biodiesel with max. 100 % FAMEgreen fuels ready: suitable for use at tank facilities filed with the new paraffinic fuels HVO or GTLwatertight up to 10 m water column - ideal for use in flood hazard areas Application To be used as part of an overfill alarm system to avoid overfilling of tanks. For battery tank systems, rectangular tanks welded on site and other indoor tanks. Suitable for fuel oil (DIN 51603-1), diesel fuel (EN 590), liquid fuels as per DIN SPEC 51603-6 and DIN/TS 51603-8 as well as biofuel and biodiesel with up to 100 % FAME (EN 14214). This product is therefore ideal for all ecologically upgraded fuel oil consuming systems that use the new paraffinic fuels HVO or GTL as an admixture or 100 %. Also for use in flood hazard areas and flood risk areas. Description PTC thermistor type level sensor consisting of probe, screw fitting, fitting for wall mounting as well as cable between probe and fitting. Watertight up to 10 m water column. Odour-tight. Metallised sleeve. The GWG level sensor connection fitting type 905 yellow is shock-resistant, impact-resistant and deformation-resistant. GWG 12 K/1 (bracket) with pre-mounted connection fitting type 905 made of grey plastic. The connection fitting is fixed to an aluminium bracket. The connection cable of the level sensor is factory-wired to the connection fitting. For tanks with direct filling (without filling pipe from the outside). See the ordering table for the available versions, fitting colours, probe and cable lengths. GWG filler cap type 906 (part no. 20430) can also be used.
