SISCO sun radiation sensor with spirit level & handwheel focuses on durable construction and convenient operation. It is designed for straightforward setup, easy tuning and low-maintenance use, supporting dependable solar radiation readings with minimal effort.
Stable Measurement Through A Dedicated Optical Sensing Chain
- A wide-spectrum sensing design keeps the output continuous and consistent as irradiance changes.
- The optical path is protected against dust buildup to help preserve long-term transmittance consistency.
- Low nonlinearity and stable annual performance reduce drift during continuous outdoor exposure.
- A short response time supports timely capture of changing solar radiation levels.
Efficient Field Deployment and Bus Integration
- The leveling structure shortens installation alignment time and helps reduce tilt-related measurement error.
- Register-level access allows direct reading of radiation values and adjustment of deviation settings for on-site calibration.
- Device address and baud rate can be configured to support multi-device RS485 bus networking.
- Wide-voltage, low-power operation reduces supply constraints and supports long-term online use.

Details
Q1: Can the sun radiation sensor connect directly to a PLC or data logger?
A1: Yes. The sun radiation sensor uses standard Modbus-RTU RS485 communication and can connect to a PLC, data logger, or monitoring system supporting Modbus-RTU.
Q2: How is the deviation value of the sun radiation sensor adjusted?
A2: The deviation value is written to register 0052H. This read/write register has a range of 0~1800, allowing deviation adjustment through Modbus-RTU commands.
Q3: What should be checked if the sun radiation sensor reads 0?
A3: Check whether a light source is present, whether the protective cover has been removed, whether the 485 bus is disconnected, whether A and B wires are reversed, whether the power supply meets the marked requirement, and whether the device is damaged.
Tips: Where should the sun radiation sensor be installed for reliable readings?
- An open location with a clear view of the sky should be selected, avoiding obstructions above and around the sun radiation sensor.
- The sun radiation sensor should be kept away from shadows cast by buildings, trees or poles throughout the day.
- Reflective surfaces such as metal roofs, water or glass should be avoided to reduce reflected radiation interference.
- Installation near heat sources, strong electromagnetic equipment or interference-prone cable routes should be avoided.
