1� PRESENTATION
dynafor™ LLZ2 dynamometers are precision stress sensors (0.3% FS) for measuring dynamic stress and indicating
loads. The capacity range is from 1 t to 20 t.
The equipment is supplied with batteries in a suitcase containing:
a) The LLZ2 dynamometer.
b) A usage and maintenance instruction manual.
c) An adjustment certificate.
d) An EC declaration of conformity.
2� OPERATING PRINCIPLE
The operating principle of the dynafor™ LLZ2 is based on measurement using strain and elongation gauges, within
its elastic limit, of a metal body subjected to traction stresses.
The device operates in all directions.
An electrical signal proportional to the load is generated by the strain gauges built into the sensor. This signal is
processed by a microprocessor analyser before being displayed on the LCD screen built into the device.
