AE402 - Overview


The wind display AE402-D was designed to operate with the combined windsensor AE402 but can be used with the separate wind sensors W400-1 and W400-2 too. Together with its power pack, a transport case and compass it forms the portable wind measuring equipment AE400 with large applicability. All single components are designed for rough, external use.
Besides its use as portable reference wind equipment it can be used together with a portable mast as wind measuring station as well as mounted on motor vehicles or on ships or used as a permanent land station.

AE402 - displayThe display AE402-D is placed in a build-in housing 135 x 135 mm and contains the sensor interfaces, the display-driver, the accumulators and the battery charger. The display can be supplied by any direct voltage between 9 and 15 Volt.
As long as the display is supplied with external voltage, the accumulators will be charged. The display can also be operated with external voltage, without containing accumulators. The operating time after recharging the accumulators is 80 h with normal brightness of the direction LED’s, switching the LED’s to bright reduces the operating time to 35 h. 

The display unit AE402-D shows wind direction by a LED-ring with 36 LED's with a resolution of 10 degrees and wind speed by a large LCD-display with 18 mm high characters. The wind speed can be displayed as instantaneous or 2 min average value. The measuring unit is selectable between m/s and knots.


The wind sensor W400-1 and W400-2 are small, sensors for wind direction and wind speed. It consists of anodised aluminium, polyamide and stainless steel. As wind speed sensor, it uses a tri-cup anemometer and a reed contact output. 4 magnets give 4 impulses per revolution. 1 m/s = 4 Hz.

As direction sensor, it uses a vane together with a ring-potentiometer with 5 k-Ohms. The sensor has a 6 m long connection cable with plug; extension cables up to 20 m are available. To fix the sensor on the tripod, it has an 8 mm female thread.

OPTION: Telescopic Masts TKM6 resp. TKM10

The telescopic masts TKM are portable masts made from aluminium with a tripod. It consists of 7 resp. up to 10 tubes with diameters from 90 mm to 30 mm. To secure the mast against strong wind span rope’s are included. To fix a Sensor or crossarm on the mast there is a threaded bolt (M8) on the top of the mast.
It can be used to support meteoroligical sensors and antennas for wireless data transmission, with confortable handling for installation of the mast and maintenence of sensors and antennas. A detailed installation instruction for sensors and mast is included with the equipment.
