Description
WSD‑1™ combines both wind speed and wind direction in a digital, smart wind sensor. Rugged, machined aluminum construction can handle extreme abuse.
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.
Feature Summary
- Wind speed (3 s, 2 min avg, and 10 min avg)
- Wind direction (3 s, 2 min avg, and 10 min avg)
- Real-time gust detection
- Anodized aluminum
- Stainless steel bearings
- No-contact wind vane direction sensor
- No direction dead spots
- Modbus RTU
- Low-power operation
- Durable construction
Key Features
Construction
WSD‑1™ is made in the USA from 6061 machined aluminum. The standard product is gold anodized. Anemometer cups are UV-stabilized polycarbonate.
All movement uses Dyacon stainless steel bearings with synthetic lubricant for long-life operation. The aluminum vane stem withstands harsh treatment. Vane and anemometer components are user-replaceable without disassembly.
WSD-1 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.
Mounting
The unique mounting tube can either be fitted over standard 3/4” pipe, such as that used for antenna towers, or used with standard 1” structural pipe fittings.
Wind Speed
The anemometer is a 3-cup mechanism uses stainless steel ball bearings.
Data Connection
Power and data are supplied through a 4-wire connection. WSD‑1 wind sensor uses a Modbus RTU slave interface.
