Tension force transducers – the measuring link

Tension force transducers are the big brothers of crane scales and are used as connecting elements between fork bearings and in rope constructions. In cranes in particular, they provide constant measurement of the tensile forces applied – they are force measurement devices in which force is applied via the bores in the measuring element.

Cranes will ultimately only operate safely if the load on the crane boom is known at all times. In such cases, tension force transducers can provide constant measurement of the load on the hook and thus prevent danger from overloadin

Thin film: the technology of choice in power measurement

tecsis customers enjoy the benefits of our tried-and-tested expertise in the use of thin film technology, with such decisive advantages as:

  • High long-term stability
  • Redundant sensor technology with no design changes
  • Measuring technology directly in-line in power train

Individual solutions as standard

We provide client-specific solutions as a matter of course, starting with the choice of steel for the tension force transducer: strain and strength parameters must first be established before the final choice of material is made. The benefit for you the customer is that all the steels used have already passed stringent quality controls. Has it passed the test? Only then will we shape the original material into the desired form at our facility. We machine our standard tension force transducers from 1.4542 stainless steel (17-4PH), obviating the need for any further corrosion treatment. If other materials are used, we coat the transducers in our on-site paint shop; client-designated coatings with a wide range of RAL paints can also be accommodated.

Tension force transducer

From pocket-sized to massive – a wide range of sizes is available

At some twenty centimetres, tecsis’ smallest tension force transducers will almost fit into a trouser pocket, while the largest are more than a metre high. The reason for our flexibility is that development and manufacturing have been working together hand in hand at tecsis for years – so even very specific geometries are no problem, as we create an individualised solution for every requirement, from rounded to angular, from integrated swivel joints to forked sensors. Our engineers work closely with our clients to adapt the design of the tension force transducers to every conceivable application – never losing sight of the individualised solution that is right for you.

Reliable results, whether in boiling heat or freezing cold

While crane scales are regularly used in plant rooms, and thus in extremely stable environmental conditions, tension force transducers have been developed for rugged use – ultimately, the temperature range within which exact readings are possible is 120°C. In practice, this means that a crane with a tecsis tension force transducer can be used in both the deserts of Dubai and the Siberian tundra with no additional calibration. In order to reduce the influence of varying temperatures on readings as much as possible, the tension force transducers automatically compensate for the ambient temperature. This guarantees minimal deviations in accuracy and thus ensures it is just as possible to use the devices at -40°C as it is at +80°C. The tension force transducers can even withstand the damp heat of a tropical climate as they comply with IP67 protection norms and standards.
