Description

The FirstRate FST200-205A is a precision-engineered anemometer and wind vane combined into a single, robust sensor. It utilizes non-contact magnetic sensing technology for both parameters, ensuring long-term reliability with no mechanical wear on the sensing elements. The integrated heating function is critical for deployments in cold climates, preventing ice formation that could impede the cup anemometer and vane movement.

Designed for continuous outdoor operation, the sensor’s die-cast aluminum alloy shell provides an IP67-equivalent level of protection against moisture and corrosion. Its internal circuitry is fully potted and shielded, offering excellent resistance to RF and electromagnetic interference, making it suitable for industrial sites and exposed meteorological stations. The wide operating temperature range of -20°C to 85°C supports deployment in virtually all environmental conditions.

Key Features

  • Heated Sensing Element: Prevents ice and frost buildup on the anemometer cups and direction vane for year-round accuracy.
  • Robust Digital Interface: RS485 Modbus output ensures noise-immune data transmission over long distances, compatible with industrial control systems.
  • Industrial-Grade Construction: Precision die-cast aluminum alloy housing offers high strength, corrosion resistance, and excellent weatherproofing.
  • Wide Operating Voltage: 10-30V DC input allows flexible power sourcing from various industrial power supplies or solar-charged batteries.
  • Non-Contact Magnetic Sensing: Provides wear-free measurement of wind speed and direction, enhancing long-term stability and reducing maintenance.
  • EMI/RFI Shielding: Internal protection ensures stable operation in electrically noisy environments like ports, cranes, and power plants.
  • Integrated Connector: M12 connector with a 5-meter cable simplifies field installation and provides a reliable, sealed connection.

Applications

  • Meteorological & Environmental Monitoring Stations: For accurate, continuous measurement of wind parameters in weather forecasting and climate research.
  • Port, Harbor & Offshore Crane Operations: Monitoring wind conditions for safe lifting operations and automatic load limiting on crawler and tower cranes.
  • Renewable Energy Site Assessment: Wind resource evaluation for potential wind farm locations and performance monitoring of existing turbines.
  • Agricultural & Greenhouse Climate Control: Automating ventilation systems based on real-time wind speed and direction data.
  • Aerial Ropeway & Cable Car Safety: Ensuring passenger cabin operations are halted during excessive wind conditions.

Frequently Asked Questions

What is the purpose of the heating element in this wind sensor?

The integrated heater prevents ice, snow, and frost from accumulating on the anemometer cups and direction vane. This ensures the moving parts remain free and the sensor delivers accurate measurements during freezing rain, sleet, or winter conditions, which is critical for year-round operational reliability in meteorological and cold-climate applications.

How do I communicate with this sensor and what protocol does it use?

The sensor communicates via a standard RS485 interface using the Modbus RTU protocol. You will need an RS485-to-USB converter or a PLC with an RS485 port to connect it to a computer or control system. The specific register map for reading wind speed and direction values is detailed in the product's user manual.

What is the maximum cable length I can use with the provided M12 cable?

The sensor includes a 5-meter cable with an M12 connector. For longer distances, you can extend the cable run using shielded, twisted-pair cable suitable for RS485 communication. The maximum reliable distance depends on baud rate and cable quality but typically can exceed 1000 meters with proper installation and termination.

Can this sensor be powered directly from a 24V industrial PLC power supply?

Yes, absolutely. The sensor's wide 10-30V DC input range is specifically designed for compatibility with common industrial voltage standards like 12V DC, 24V DC, and 28V DC. You can connect it directly to the auxiliary power output of a PLC or a dedicated 24V DC power supply without requiring an additional voltage regulator.
