with Thin-Film Sensor, from 1 kN up to 100 kN
Tension/compression force transducer with thin film implant
In addition to our force transducer program with bonded foils, a 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 a relative linearity error of 0.2%, the tension/compression force transducers 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). Tension/compression force transducers can be applied directly into the force flux.
They are used for weight measuring or as an overload protection. In machineries they are used to monitor press capacities and clamping forces. Mounted indirectly they can be used as torque supports in order to supervise momentums. Different output signals are available: either a not amplified output signal mV/V- or amplified output signals (4...20 mA, 0...10V).
These force transducers fulfil the regulations of EMC according to directive EN 61326.
F23S1 Safety version
Version acc. to the requirements for functional safety acc. Machinery Directive 2006/42/EG, applies only in combination with a safe control, for example ELMS1 overload protection.
ATEX / IECEx (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.
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.
