These pictograms indicate that the product cannot be disposed of with waste,
according to the European Directive DEEE (2002/96/CE), the Directive applying to
batteries disposal (2006/66/CE) and local waste regulations following these
directives. When a chemical toxicity pictogram is printed below this one, according to the Directive
applying to batteries disposal, it means that Heavy Metals are present (Hg = mercury, Cd = cadmium,
Pb = lead) in the battery at or above the applicable cut-off concentration specified in the Directive.
This product must be given to a disposal centre, i.e. when you purchase a new similar product, or to a
designated collection point for the recycling of waste electrical and electronic equipment (EEE).
Wrong behaviour in disposal can have consequences on the environment and human health,
because of the potentially hazardous substances generally associated to electric and electronic
equipment. Your contribution to a correct disposal of this product will contribute to efficient use of
natural resources.
F. Warranty
Your LCJ CAPTEURS product is warranted against manufacturing defects in materials and
workmanship for a period of 24 months from the date of purchase. LCJ Capteurs will repair or
replace, at its discretion, faulty products free of charge at their premises. The warranty does not cover
the installation labour and shipping costs of the faulty parts. A proof of purchase can be required
when processing the warranty claim by written. Once LCJ Capteurs has approved the warranty claim,
the sensor must be sent to their workshop address. LCJ Capteurs ensures that each wind sensor is
tested and calibrated before despatch.
The warranty does not apply in the following cases:
1. Damage resulting from misuse.
2. Improper installation or inappropriate conditions of operation.
3. If the product has been damaged, opened or repaired by an unapproved agent.
4. Damage resulting from lightning, fire or any similar circumstances.
Warranty is void if operation, use, installation and technical service instructions have not been
followed and if a repair has been carried out without prior agreement.
G. Product return
Contact your dealer prior to returning a product to LCJ Capteurs. A Return Merchandise Authorisation
(RMA) must be issued and received before sending a product back.
2. Introduction
A conventional wind vane-anemometer includes mechanical rotating parts. These parts are subject to
wear and they represent sources of failure of the sensor. Our ultrasonic sensor has been designed to
avoid this and to ensure reliable and stable operation. This ultrasonic wind vane-anemometer shows
very stable results over a long term and with no maintenance.
The sound (and ultrasound) is conveyed by the
movement of the fluid in which it crosses. The
electroacoustic transducers (1) communicate
between themselves two by two using ultrasonic
signals (2) to determine, following the orthogonal
axes, the wave transit time differences induced by
the air flow (3). The measurements are combined in
an integrated calculation to establish the wind speed and its direction in relation to a reference axis.
The temperature measurements are used for calibration corrections. The sensor’s design minimises
the effect of heel angle (4). The CV7 range of products features lateral transducers delivering four
independent measurements.
