First Class Wind Transmitter
The First Class wind transmitters are designed to evaluate the location and capacity of future wind power systems. The anemometer measures the horizontal component of wind speed and the direction transmitter detects the horizontal wind direction. The measured value from each is available as a digital signal at the output.
The rotation of the carbon-fibre reinforced plastic cup star on the anemometer, is scanned opto-electronically and converted into a square wave signal. The frequency of this signal is proportional to the number of rotations. The measured value is available as a digital signal output.
The light weight, aluminum wind vane runs on ball bearings and through magnetic coupling to an integrated potentiometer provides a directional signal that is friction free. Available signals include resistance, mA, V or digital.
Compact Wind Speed & Direction Transmitters
Our compact wind transmitters have the perfect price performance ratio for most commercial and industrial applications. Their built-in heaters make them serviceable in winter conditions and their standard 4-20mA output signal makes them simple to interface to building control panels or industrial chart recorders.
The wind velocity is measured by means of a low inertia plastic cup-star whose ball-bearing axis is connected to a slotted disk. This disk is scanned opto-electronically and supplies 11 pulses with every rotation. These pulses are converted in the instrument to 4 ... 20mA.
The wind direction is measured by means of a low inertia metallic wind vane whose ball-bearing axis is connected to a slotted disk. The code disk is scanned opto-electronically and has been built with a 5 bit Gray Code to give a resolution of 11.25 degrees. This Gray-Code is converted in the instrument to 4 ... 20mA.
Classic Wind Speed Transmitter
The wind transmitter is used for the registration of the horizontal component of the wind velocity. The measuring value will be placed at the output as analog signal. The signal can be given to display instruments, recording instruments, datalogger as well as process wise systems. The wind transmitter is equipped with an electronically regulated heating system in order to prevent ice and frost from the ball bearings and the outer rotation parts (please refer to instrument models).
Power supply unit provides the transmitter and the heating system with current. It is advisable to attach a Lightning rod in areas with considerable lightning activity.
The Ultrasonic Anemometer 2D is designed to detect the horizontal components of wind speed and wind direction as well as the virtual temperature in two dimensions. Due to its very short measurement intervals, the instrument is ideal for the inertia-free measurement of gusts and peak values.
The measured data are available as analogue signals and as a data telegram over a serial interface. The sensors instrument as well as the instrument body are automatically heated so that the measuring results, in case of critical ambient temperatures, are not affected by ice, snow or rainfall.
