Compression force transducer with thin-film sensor

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 1%, the new 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). Compression force transducers are often mounted directly in the force flow. They are used for weight applications or overload measurement. Inside of machines they measure e.g. press, clamping or joining forces. Indirect mounted transducers can beused as torque supports for measurement of moments as well. Different output signals are available: analogue standard output signals 4...20 mA, 0...10V or an mV/V output signal. These force transducers fulfil the regulations of EMC according to directive EN 61326.

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.

SIL-3 (Option)
In cooperation with the TÜV Süddeutschland a special security electronics has been developed for theatre and stage applications. It fulfils security standard SIL 3 with a 2-channel PC control in connection. This international security standard for systems and processes is based on the standards IEC 61508 and 61511. The latter is used for ascertaining risk potentials of (engineering) systems. Depending on the potential existing risk a risk reduction has to be made. If automation components are used for that, they have to fulfil the demands of IEC 61508. Both standards subdivide systems and risk reducing actions in four security steps: SIL1...SIL4 (Safety Integrity Level) – from small up to very high risks. If persons are allowed to stay under hanging loads, e.g. in theatres, security level 3 (SIL 3) is valid.

UL-Certification (Option)
tecsis force transducers are also available with UL approval.
