1 PRESENTATION
The LLX2 display units receive, process and display the signals output by an LLX2 or LLXh sensor or
any other load cell (equipped with strain gauges) associated to an LLXt Module.
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 unequivocal
identification in the event of a multiple set-up.
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. A display unit can be
configured as Master or Slave within a network.
The equipment is supplied with its battery in a cardboard package, 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 LLX2 System consists in using a strain gauge to measure the elongation,
within its elastic limit, of a metal body subjected to tensile stresses.
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 the sensor models equipped with LLX2 technology regardless of
their capacity. Unless otherwise ordered, the radio link-up between the LLXh and 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.
