TR-N1C-P30-2 - Leader Electronic Co., Ltd.

FORCE TRANSDUCER FOR MEASURING THE TENSION

ON FIXED OR ROTATING SPINDLES

MECHANICAL DIMENSIONS

Main features

• Range of measurement: from 100 N to 1kN

• Accuracy class: 0,5%

• Corrosion resistant

• Internally generated calibration signal

• Orientation of the axis of maximum sensitivity for 35°

independently from the position of the fixing holes

• Grade of protection: IP65 (DIN 40050)

• Integrated protection against overloads

TR series force transducers are used to measure the tension

that plastic films or tapes exert on the guide rollers of the

machinery used to coil them.

Mounted at the ends of a fixed or transmission shaft on the

machine chassis, they perform the function of force sensors

and bearing for the ends of the shaft.

They are used on both fixed and rotating shafts.

TR transducers are supplied with the adaptor flange for fixing,

with 4 M6 screws or with one central M10 or M12 screw.

Cells connected in parallel

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.
