Description

The SN-3000-FSJT-I20 wind speed sensor employs a classic three-cup anemometer design, where cup rotation speed is directly proportional to wind velocity. This mechanical motion is converted into a precise 4-20mA current loop signal, providing a noise-immune output ideal for long-distance transmission in industrial environments. The sensor’s internal high-performance bearings ensure minimal rotational resistance and consistent accuracy across its operational lifespan.

Engineered for harsh environments, its polycarbonate shell offers excellent resistance to UV radiation, corrosion, and mechanical impact. The bottom cable outlet design eliminates common failure points associated with top-mounted connectors, enhancing long-term weatherproof integrity. This sensor is a critical component for accurate wind speed monitoring in applications demanding reliability and precision.

Key Features

  • High-accuracy measurement with a defined error of ±(0.2 + 0.03·V) m/s, where V is the measured speed.
  • Robust polycarbonate composite housing ensures durability and resistance to corrosion, rust, and erosion.
  • Low-inertia three-cup rotor design enables a fast response time and sensitive detection of low wind speeds.
  • 4-20mA current loop output provides excellent noise immunity and is standard for industrial process control.
  • Bottom cable exit design enhances long-term waterproof performance and eliminates aviation plug seal aging issues.
  • Wide operating temperature range from -20°C to +60°C (extended option to -40°C).
  • Anti-electromagnetic interference (EMI) processing ensures stable signal integrity in electrically noisy environments.
  • Optimized performance-to-cost ratio for professional-grade wind monitoring applications.

Applications

  • Industrial weather stations and environmental monitoring networks for wind data collection.
  • Wind resource assessment and performance monitoring for small-scale wind turbines.
  • HVAC system airflow monitoring and control in large commercial buildings.
  • Port, dock, and maritime operations for safety and logistical planning.
  • Agricultural and greenhouse climate control systems for ventilation management.

Frequently Asked Questions

What is the output signal of the SN-3000-FSJT-I20 sensor and how do I interface with it?

This specific variant outputs a standard 4-20mA analog current signal. To interface, connect the sensor's power (12-24V DC) and signal wires to a PLC analog input module, data logger, or a microcontroller equipped with a current-to-voltage converter (typically using a precision resistor). The 4mA output corresponds to 0 m/s, and 20mA corresponds to 70 m/s.

Can this sensor be used outdoors permanently, and what is its IP rating?

Yes, it is designed for permanent outdoor installation. The polycarbonate housing is highly resistant to corrosion, UV degradation, and physical impact. While a specific IP rating isn't listed in the provided specs, the design featuring a bottom cable exit and sealed bearings is intended for long-term weatherproof operation in rain and harsh environments.

What is the difference between the I20 (4-20mA) model and other output variants like pulse or RS485?

The I20 model provides a continuous analog 4-20mA signal, ideal for real-time monitoring and direct integration with most industrial control systems. Pulse output variants provide a frequency signal proportional to wind speed, suitable for counting applications. RS485/Modbus variants offer digital communication for networked sensor arrays, enabling multiple devices on a single bus with precise digital data.
