Strain gauge WTB 4500 kg (Special developments)
Strain gauges of the WTB model are intended for measuring cable tension. Sensors are built into the cables when they are in an untensioned state. This model is used in crane systems for lifting goods, elevator systems, as well as everywhere where it is necessary to measure and control the load and overload of cables.
The body of the WTB strain gauge is made of steel with a reliable anti-corrosion coating, it is completely protected from the influence of dust, moisture, and has a protection degree of IP68. Tensor resistors are protected by a welded stainless steel cover.
