Load pin with thin-film sensor for Heavy Duty applications

The rugged design of these force transducers is needed for use in harsh operating conditions such as in cranes, construction machinery and for maritime applications. The sensors are suitable for force measurement in pulleys, fork bearings and roller bearings. The force is measured either directly in the full force flow or at a torque support in these locations. Because of their structural design, measuring axles can be installed as a direct substitute for clevis pins in existing structures. Sensitive components such as connectors or electronics are given mechanically protection. 

In addition to our force transducer program with bonded foils, this new force transducer with a welded thin film sensor was developed. The usage of standardised sensors, which are welded into the measuring element, makes an automated manufacturing possible. Thin film sensors, produced by very modern manufacturing technology, have all advantages of the conventional bonded foil strain gauges, but without having their substantial disadvantages (temperature drifts of the glue and creeping). 

Different output signals are available: analogue standard output signals 4...20 mA, 0...10V or an mV/V output signal. The load pins meet EMC requirements acc. to EN 61326-1:2006, EN 61326-2-3:2006 and works reliable in difficult electromagnetic environment.For safety relevant applications the load pins are optionally available in a redundant version.

ATEX (Option)
Only equipment and protective systems with the corresponding certification and markings are to be put into operation in potentially explosive areas. Our force transducers with a thin-film measuring cell and integrated amplifier now have approval according to directive 94/9/EC in equipment group II (non-mining products), category 2G for zones 1 and 2 (gases). Other zones on request.
