Pyranometer Total Solar Radiation Sensor Sunlight Detector Photoelectric Type Transducer
Pyranometer Irradiance Sensor Analog Type
Product overview
The MU300AL-RA-* solar radiation sensor uses the photoelectric principle to measure the total radiation under sunlight. The radiation sensor uses high-precision photosensitive elements, broad spectrum absorption, high absorption in the full spectrum range, and good stability; at the same time, a dust cover with a light transmittance of 95% is installed outside the sensing element, and the dust cover is specially treated to reduce dust Adsorption can effectively prevent environmental factors from interfering with internal components, and can more accurately measure solar radiation.
The product adopts analog output, which can read and convert the current solar radiation value, and the wiring method is simple. The appearance is small and beautiful, and it takes up little installation space. Products are widely used in solar energy utilization, meteorology, agriculture, building materials aging and air pollution and other departments to measure solar radiation energy.

Installation Method
1. Use screws to pass through the mounting holes on the sensor to fix the sensor on the mounting bracket
2. Make sure that the device is parallel to the ground (adjustable thumb screw and check the state of the horizontal bubble to determine whether it is parallel)
3. After the installation is complete, remove the protective cover
Meaning of analog parameter
Current output signal conversion calculation
For example, the range is 0~1800W/㎡, 4~20mA output, when the output signal is 12mA, calculate the current solar radiation value. The solar radiation range span is 1800W/㎡, expressed by a 16mA current signal, 1800W/㎡/16mA=112.5W/㎡/mA, that is, the current 1mA represents the solar radiation change 112.5W/㎡, and the measured value is 12mA-4mA=8mA. 8mA*112.5W/㎡/mA=900W/㎡, the current solar radiation value is 900W/㎡.
Voltage signal output conversion calculation
For example, the range is 0~1800W/㎡, 0-10V output, when the output signal is 5V, calculate the current solar radiation value. The solar radiation range span is 1800W/㎡, expressed by a 10V voltage signal, 1800W/㎡/10V=180W/㎡/V, that is, the voltage 1V represents the solar radiation change 180W/㎡, and the measured value is 5V-0V=5V, 5V* 180W/㎡/V=900W/㎡, the current solar radiation value is 900W/㎡.
