Litemeter Current: Sun radiation sensor

Litemeter CURRENT - Analog silicon cell pyranometerLitemeter Current is a radiation sensor with a high efficiency monocrystalline silicon cell.
Litemeter Current is a small silicon cell pyranometer with great potential.
It’s an analog solarimeter suitable for small and medium-size plants. It needs a external power supply.

The Current output 4-20mA allows the analog signal to remain unchanged in cases whereas the distance between the sensor and the control unit is 10m and more, or in disturbed areas. Distance up to 20-35m if there’s no signal interference.

Litemeter Current is simple, affordable and easy to install.

Key Features:

  • Output 4-20 mA
  • Power supply 8-30Vdc
  • Ease of installation and use
  • Calibrated with a Sunmeter reference which is adjusted every 6 months on the K&Z CMP22 pyranometer of the Teolo Weather Center
  • Complies with IEC 60904
  • Equipped with a quick mounting bracket ready to install.
