Shear Beam with Thin-Film Sensor, from 2 kN up to 100 kN
In addition to our force transducer program with bonded foils, a 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. Combined with an accuracy of 0,5%, the new shear beams are also of interest for OEM applications due to the attractive price- performance ratio. 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). Shear beams are specially used as torque support of drives or as standard component in weighing applications. Different output signals are available: analogue standard-output signals (4...20 mA, 0...10V). Shear beams fulfil the regulations of EMC according to directive EN 61326.
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.
Signal jump (Option)
Safety electronics have been developed especially for theatre and stage applications. With a signal jump, a function test is carried out in an interval of 24 hours in order to monitor the safe function of the force transducer.
