Gefran TH Data Sheet
TH
FORCE TRANSDUCER FOR TENSION/COMPRESSION
APPLICATIONS
Main features
• Range of measurement: from 10 to 100 kN
• Accuracy class: 0,2%
• All stainless steel construction
• Corrosion resistant
• Internally generated calibration signal
• Grade of protection: IP65 (DIN 40050)
The TH series force transducers are ideal for systems
that measure tension or compression force in industrial
applications, where accuracy and reliability are important, even in harsh environments.
The disposition of the (8) strain gauges of the measurement bridges uses the deformation produced by the
shear force of the applied load. It is thus possible to
make accurate force transducers that are rugged and
insensitive to lateral loads.
The transducer is machined from a solid block of
stainless steel and contains no welds or joints.
The electrical circuit is protected by sealed formed
stainless steel plates.

In systems that use several cells, the parallel connection automatically sums the loads on each individual cell.
Using this method of measurement, the maximum load will be the sum of the loads on the individual cells and the sensitivity will be the
average value of these cells.
It is important that the user ensures that no cell is stessed beyond its maximum rating under any load condition.
