DSV39A has a square plate and a counterweight mounted on a central shaft to measure the wind direction. The shaft is connected to an optical rotary encoder, which convert the angle into a 6-bit Gray code. All electronic components are protected from power surges with resistors and Zener diodes. This system guarantees accuracy to within 5,5 degrees. All parts of the device are made either from the stainless steel and naturally anodized aluminium.

The shaft is supported by two bearings. The upper one is radial ertalyte while the lower one is a double sapphire bearing. On the underside of the instrument is a carrying bracket and a watertight connector. The bore of the bracket is 25mm wide by 40mm deep.

DSV39 is usually paired with a DHV39 wind speed sensor. In most cases the two instruments are mounted on a single cross-beam with a junction box in the middle and a lightning rod for protection. Individual instruments are installed separately, which makes power surges less likely to damage them. The instrument is connected via a 10 wire shielded cable either directly to the measuring equipment or through a junction box. The instrument casing is grounded through the shielding of the cable. Maintenance is virtually unnecessary and only needs to be carried out when the performance of the instrument has changed significantly. Extra stress from icing cannot damage the instrument.
