Solar meter - the irradiation sensor

adl sr sonnenmeter 

The irradiation sensor determines the irradiance and gives the
momentary irradiation value in W / m². In addition, the sensor determines
Optionally the module temperature of solar panels. The analogue
The solar cell signal is converted to a digital RS485 signal in the sensor.
The sensors are individually calibrated and re-imported in Germany
ISO 9001 manufactured.


Advantages and functions

  • each sensor is delivered with an individual calibration
  • Addressable RS485 bus system
  • Each bus can connect up to 253 sensors of different types
    (Examples Sensors: Sun Sensor, Digital Inputs, Analog Inputs, etc.)
  • easy construction
  • no loss of accuracy due to cable lengths
  • Optionally, temperature and wind speed can be measured
