Modbus irradiance sensors are designed for professional use in industrial, commercial and photovoltaic plants.

The irradiance sensor works as a concentrator for several sensors. All measured weather data is transmitted to the data loggers and receiving units via a 2-wire RS485 bus with Modbus RTU protocol.

- Class A compliance.
- Quick and easy installation.
- Similar structure with photovoltaic panels.
- Free software update.
- Compatible with SunSpec (for Modbus RTU).
- Remote configuration service.
- 5 years warranty.

It is a two-axis static ultrasonic anemometer used to make accurate measurements of wind speed and direction under all environmental conditions. It is capable of measuring wind speeds of up to 85 m/s without losing precision.

It has a heating option for quick defrosting. A model with an anodized aluminum alloy casing with anti-corrosion coating is available. This feature allows the instrument to be used even in particularly aggressive environments. The anemometer meets the requirements of MIL-STD-810G Method 509.6 (salt spray corrosion test). Its high immunity to electromagnetic interference makes it suitable for measurements in electrically noisy environments.

All measured weather data is transferred to the data loggers and receiving units via a 2-wire RS485 bus with Modbus RTU protocol. This sensor is also equipped with two analog outputs for wind speed and direction, factory configurable within 4-20 mA (standard), 0…1 V, 0…5 V or 0…10 V (to be specified when ordering).
