Telemetry Load Link

c2ag_295x234_3_WLL

The WLL series of wireless load monitoring links have been designed for lifting and weighing in rugged or harsh environments, being manufactured from stainless steel for corrosion resistance. It also comes supplied complete with a 3.1b material certificate as standard, complies with the European Machinery Directive 2006/42/EC and is supplied in a robust storage case.

The WLL wireless series are simple to install and are matched to standard shackle sizes. The unique wireless housing is manufactured from semi-aromatic polyamide plastic making the load link far more compact and reducing the overall product weight. Located in the housing are two AAA alkaline batteries which can be easily accessed by removing the telemetry housing cover, while the internal electronics underneath remain completely sealed. The antenna is also internally mounted, protecting it from accidental damage during use and handling. The batteries are standard AAA alkaline batteries, which are readily available and low cost.

The wireless WLL is also supplied as standard with a handheld battery powered display (T24-HS-LS) which can display in both tonnes or lbs, or alternatively, for multi-link applications, a single display (T24-HA) can address up to 12 links for individual monitoring, or for summation/balancing applications. The built in wireless electronics operates on the 2.4GHz license free frequency, with a robust proprietary protocol, providing interference free communications.
