Description

The RS-RA-N01-AL-EX utilizes a high-precision photoelectric sensing element to capture total solar irradiance, a critical parameter for assessing solar energy potential and environmental conditions. Its advanced optical design includes a high-transmittance, dust-proof protective cover that minimizes measurement drift and ensures long-term stability, with an annual stability rating of ≤±2%.

Engineered for professional meteorological and energy monitoring applications, the sensor features a built-in level meter for precise installation alignment and a fast response time of ≤10 seconds. Its robust aluminum housing and IP-rated construction (implied by environmental specs) provide reliable operation across an extended temperature range of -25°C to +60°C and 0-100% RH humidity.

Key Features

  • High-precision photosensitive sensing element with <±2% nonlinear accuracy.
  • Full-spectrum absorption across 0.3–3μm wavelength range for comprehensive solar radiation measurement.
  • Industrial RS485 communication interface with Modbus RTU protocol support.
  • High-transparency, anti-dust protective cover for sustained accuracy and minimal maintenance.
  • Wide operating voltage range of 7–30V DC, enabling flexible power sourcing.
  • Compact and durable aluminum alloy housing for resilience in outdoor environments.
  • Integrated bubble level for straightforward horizontal installation and alignment.
  • Low power consumption of 0.06W for energy-efficient continuous monitoring.

Applications

  • Solar photovoltaic (PV) farm performance monitoring and yield assessment.
  • Professional meteorological stations for climate research and weather forecasting.
  • Agricultural environmental monitoring for evapotranspiration and crop modeling.
  • Building energy management systems (BEMS) for solar gain analysis.
  • Research and educational platforms for renewable energy and environmental science.

Frequently Asked Questions

What is the communication protocol and wiring for this solar radiation sensor?

The sensor uses an RS485 interface and communicates via the Modbus RTU protocol. It is typically wired using a 4-wire connection (A, B, power+, and ground) as per the included cable. Ensure your host device (PLC, data logger, or gateway) is configured for Modbus RTU slave addressing and uses matching baud rate, parity, and stop bit settings for successful data polling.

What is the required power supply, and can it be solar-powered?

The sensor operates from a wide DC voltage range of 7 to 30 volts, consuming only 0.06W. This low power requirement and wide input range make it highly suitable for direct connection to 12V or 24V industrial power supplies or for integration into off-grid, solar-powered monitoring stations with appropriate voltage regulation.

How do I install and calibrate this sensor for accurate measurements?

For accurate hemispherical measurement, mount the sensor horizontally using the provided screw set and utilize the integrated bubble level for alignment. The sensor is pre-calibrated and features high annual stability (≤±2%). No user calibration is typically required, but periodic cleaning of the high-transparency dust cover is recommended to maintain optimal accuracy.

What environmental conditions can this sensor withstand?

Built with a durable aluminum housing, the sensor is designed for continuous outdoor operation. It is rated for an operating temperature range of -25°C to +60°C and can withstand 0-100% relative humidity. Its design includes environmental protection features suitable for harsh meteorological and industrial field conditions.

Package Includes

  • 1 x Renke RS-RA-N01-AL-EX Solar Radiation Sensor
  • 1 x Screw Set for mounting
  • 1 x 4-pin male connector cable (70 cm length)
