Solar Radiation Sensor Manufacturer,Supplier and Exporter in India
Product Code : EL-TWL-11830
Quick Answer: The Solar Radiation Sensor measures global radiation, the sum of direct and diffuse solar radiation at the point of measurement, with a hermetically sealed silicon photodiode as its transducer. An included amplifier converts the photodiode current into 0 to +2.5 VDC.

Key Features
Hermetically sealed silicon photodiode with wide spectral response (400 to 1100 nm).
Built-in amplifier output 0 to +2.5 VDC.
Cutoff ring for cosine response, plus level indicator and sun-alignment fins.
Outer shell shields the body from thermal radiation and allows convection cooling.
Diffuser welded to the body for a weather-tight seal; water run-off path between shield and body.
Spring-loaded mounting screws for quick, accurate levelling.

About This Product
The console it is used with calculates and displays solar radiance from the sensor's output voltage and can integrate the values to show total incident energy over a set period. The shell, diffuser and run-off design keep the sensor working outdoors with little heating of its interior and little chance of rain or irrigation water becoming trapped.
Frequently Asked Questions
How is the sensor levelled?
Spring-loaded mounting screws work together with the level indicator for quick and accurate levelling, and fins help align the sensor with the sun's rays.
What does the output represent?
The amplifier gives 0 to +2.5 VDC from the photodiode current; the console calculates solar radiance from this voltage and can total the incident energy over a set period.
How long is the cable?
A 3 ft (0.9 m), 4-conductor 26 AWG cable comes with the sensor.
