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.
(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.
(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.
