Wind Sensor – Modbus


WSD‑1TM combines wind speed and direction sensors into a rugged package. Digital sensor data are delivered using the Modbus protocol, which allows for long cable runs to computers, programmable logic controllers (PLCs), and some data loggers.

Product Details


Wind Sensor Introduction


Manuals & Software

WSD‑1TM is a high-quality, professional meteorological instrument designed for industrial, agricultural, small airport, and research applications. WSD‑1 is a low‑power, digital output anemometer with combined wind vane.

WSD‑1 is a standard component of Dyacon MS‑100 series weather stations.

As a native Modbus sensor, WSD‑1 is ideally suited for industrial applications and can be connected directly to PLCs, SCADA equipment, and DCS to directly add environmental data for other automation and logging applications.

Like all Dyacon equipment, WSD-1 is made in the USA.

Key Features

WSD‑1TM is made in the USA from 6061 machined aluminum. The standard product is gold anodized. Anemometer cups are UV-stabilized polycarbonate.

Several sun-fast colors are available to value-added resellers, including colorless (clear), electroless black, blue, and red. All movement uses Dyacon ceramic hybrid bearings with synthetic lubricant for long-life operation. The fiberglass vane stem withstands harsh treatment. Vane and anemometer components are user-replaceable without disassembly.

The slim mechanical construction minimizes snow accumulation.

Wind Direction
The wind direction sensor utilizes a no-contact sensor for high reliability and high accuracy, and, unlike potentiometer sensors, it has NO dead spots.

The unique mounting tube can either be fitted over standard 3/4” conduit, such as that used for antenna towers, or used with standard 1” structural pipe fittings.

Wind Speed
The anemometer is a 3-cup mechanism that utilizes Dyacon ceramic hybrid bearings.

Data Connection
Power and data are supplied through a 4-wire connection. The WSD‑1 wind sensor uses a Modbus slave interface. Drawing
