Select the output, supply and mounting scope together
The reviewed Class C documents support the performance values below. Output, supply, cable, mounting and calibration deliverables remain order-specific.
- The reviewed instrument classification is ISO 9060:2018 Class C, with a 0-2000 W/m² range and 300-3200 nm spectral response.
- Sensitivity is 7-14 µV/(W/m²). Non-linearity is below ±3%, response time is no more than 60 seconds to 95%, and annual stability is below ±3% per year.
- Performance is expressed through the Class C component specifications rather than one generic accuracy number.
- Order one output configuration. Passive 0-20 mV needs no external supply; powered 4-20 mA, 0-5 V, RS485 Modbus RTU and SDI-12 versions use the supply defined for that ordered output.
- The reviewed operating range is -40 to +80 °C with IP67 protection. Final cable, connector, mounting bracket and surge-protection scope are confirmed for the installation.
- The reviewed calibration basis is ISO 9847, with a two-year recalibration interval. The quotation must state whether a calibration report or other traceability document is included.
Typical applications
- PV plant reference irradiance and performance-ratio input
- Automatic weather-station global solar-radiation measurement
- Agricultural evapotranspiration and irrigation-support datasets
- Solar-resource assessment and environmental monitoring
- Remote irradiance logging through a selected RTU, logger or acquisition gateway
