Presentation - Tractel Dynafor LLX2 1 t Operation And Maintenance Manual

1 PRESENTATION

The dynafor LLX2 dynamometers are precision appliances (0.1% ISO 376 . 21°C), for measuring
™
pulling force and indicating loads. The capacity scale ranges from 500 daN to 10000 daN.
A dynafor LLX2 is made up of a sensor and a mobile display unit.
™
A two-way radio link-up using the 2.4 GHz wave band conects the two components.
16 radio channels are used. Each display unit and sensor have their own address, enabling unequi vocal
identification in the event of a multiple set-up.
The specific, patented shape of the attaching head enables you to use either standard shackles or
standardised accessories for chains.
The LLX2 is available in two versions: Standard version with interlinking anchoring rings in the
perpendicular surfaces, or an optional version with the anchoring rings both on the same side (see Page
9 diagram). The standard version enables articulation of lifting accessories on both sides, thus avoiding
stresses due to load movements and enhancing appliance precision.
These assemblies are put together on our production line and cannot be modified later by the user.
The technologies implemented on a radio and software level offer, aside from the standard uses to be
expected from an industrial dynamometer, multiple configuration possibilities that combine several
sensors with several display units. They also offer access to advanced function such as: saving,
threshold management, monitoring etc.
The PC – USB link permits to dowload, save and manage measurements data.
The standard version of the equipment comes with batteries and power pack in a carrying case containing:
a) A sensor
b) A display unit and battery charger
c) An operating and maintenance instruction manual
d) A certificate of adjustment
e) A certificate of CE compliance
1.1 Operating Principle
The operating principle of the dynafor
within its limits of elasticity, of a metal body subjected to traction stress.
The appliance will work in all directions.
The sensor generates an electrical signal that is proportional to the load. This signal is processed by a
micro-processor analyser and then transmitted via radio waves to the display unit, which immediately
displays the load applied to the sensor to which it is linked.
When switched on, the sensor data, such as identification and date of last metrology check, is displayed
on the display unit.
The display unit is compatible with all of the LLX2 model sensors, irrespective of their capacity. Unless
otherwise ordered, the radio link-up between the LLX2 sensor and the display unit is set definitively in
the factory before dispatch. After this, the radio link can be configured by the user to meet their
requirements.
LLX2 is based on strain gauge measurement of the extension,
