SISCO global radiation sensor combines a pyranometer design with flexible signal transmission options. It supports RS485 Modbus-RTU, 4–20mA, 0–5V, and 0–10V outputs, allowing the sensor to connect directly with different data acquisition, monitoring, and control systems.
Radiation Measurement and Signal Conversion
- The thermopile sensing structure converts incoming radiation into an electrical signal.
- Temperature compensation helps minimize measurement deviations caused by temperature changes.
- Fast response allows changes in radiation intensity to be captured promptly.
- Continuous measurement supports monitoring of changing radiation conditions.
- Low nonlinear error helps maintain consistent measurement results.
Double-Layer Optical Protection Design
- A transparent double-layer glass cover allows radiation to reach the sensing element efficiently.
- Special surface treatment reduces dust adhesion on the cover.
- The double-layer cover structure reduces air convection effects.
- Scattered radiation can be measured with the integrated radiation shield.
- The compact housing takes up limited space during installation.
Applications
SISCO global radiation sensor is suitable for solar radiation monitoring in solar energy systems, meteorological stations, agricultural environments, building material testing, and air pollution monitoring, where continuous measurement of incoming radiation supports data collection and environmental assessment.

Details
Q1: What does a global radiation sensor measure?
A1: A global radiation sensor measures incoming solar radiation and converts the received radiation energy into an electrical signal for subsequent data collection.
Q2: How should a global radiation sensor be installed for measurement?
A2: A global radiation sensor should be installed horizontally and parallel to the ground, with an open surrounding area and no objects blocking the sensing surface.
Q3: Can a global radiation sensor be configured for different communication settings?
A3: For the RS485 version, communication parameters such as the device address and baud rate can be configured according to system requirements.
Tips: How can a global radiation sensor maintain consistent measurement performance?
- Keep the glass cover clean and free from dust or other deposits.
- Check the cover regularly to ensure there is no water accumulation inside.
- After prolonged exposure to heavy rain, snow, or ice, protect the sensor from extended weather exposure.
- For the RS485 version, verify that the wiring and power supply are correct before operation.
- After more than two years of use, recalibration of sensitivity is recommended by the manufacturer or a qualified measurement department.
