Lambrecht METEOROLOGY 14576-24 V Operating Instructions Manual

Operating Instructions
Wind Sensors METEOROLOGY (145x6)
Versions
The METEOROLOGY family of sensors comprises the heated
sensors 14576-24 V for wind speed and 14566-24 V for wind
direction as well as the unheated sensors 14576 I (wind
speed) and 14566 F1000 (wind direction).
Measuring Elements
The heated models use optoelectronic measuring elements to
detect, without any wear, the rotation of the cup anemometer
and the wind vane, respectively.
The unheated models use measuring elements with extremely
low friction to detect rotations; this also guarantees a long
service life.

Operating Instructions
Cup Anemometer
The three-armed cup anemometer with a diameter of 215 mm
is rotated by the wind. The number of revolutions is a measure
of the wind speed.
The cup anemometer's constructive features that are per-
manently controlled by the quality management during the
manufacturing process ensure optimum linearity.
Wind Vane
The single-bladed wind vane has a great radius so that even
small wind speeds move the wind vane to the corresponding
wind direction.
The size and form of the wind vane are optimized for a low
starting value, and an excellent compromise regarding its
dynamic properties (inertia, proper frequency) has been
achieved.
