Models F7301, F73C1, F73S1 Tension link
With thin-film technology from 5 kN
Tension links are designed for static and dynamic measurement tasks in the direct flux of force. As a load-bearing component in existing constructions, they determine the tension forces in a wide scope of applications.
Tension links of these models are often used in hoist and crane systems as torque support or rope fix point for load measurements. Further application areas are special machine constructions, e. g. in polymer processing machines.
Appropriate technical and regional approvals are available as an option.
The tension links of the model F73x1 are either made of high-strength, corrosion-resistant stainless steel 1.4542 or robust fine-grained steel with surface protection. Due to their properties, these materials are particularly suitable for the applications of tension links.
As output signals, the common active current and voltage outputs are available (4 …. 20 mA, 0 … 10 V).
Redundant output signals and CANopen® protocols are also possible.
These force transducers can be integrated into a certified WIKA overload protection with model ELMS1 (DIN EN ISO 13849-1 with PL d/cat. 3).
