1- PRESENTATION

1-1 Operating principle

The DYNAFOR® LLX range of load indicating devices are highly accurate instruments formeasuring tensile forces and suitable for a wide variety of applications where an instant indicationof the load applied is required.

The principle of the DYNAFOR® is the movement of a material within its elastic limit, usingbonded strain gauges to give a signal, relative to the load applied. The unit will operate in anyposition.

The DYNAFOR® LLX range uses microprocessor based electronics to process the signal to givean accurate and immediate read-out, on the LCD, of the load applied.

The range of DYNAFOR® LLX load indicators comprises models from 250 kg to 250 t.

The DYNAFOR® LLX unit is supplied complete with a set of Alkaline long life batteries, within acarrying case, together with an operating manual, 2 calibration certificates and a CE declarationof conformity.
