Litemeter Voltage: Sun radiation and temperature sensor

solar radiation and temperature sensorLitemeter Voltage is a radiation and temperature sensor with monocrystalline silicon cell. This solarimeter has two analog outputs 0-10V, which provide the value of irradiation and temperature of the cell. The technology inside allows it to ensure a high degree of linearity in the measurements and reliability in accordance with the IEC 60904. The sensor is temperature compensated. The accurate calibration which is carried out allows high reliability of the measures. It’s available in two calibration options for the ranges of irradiance and temperature depending on the climate zone. Through the ordering code you choose the features most appropriate to the area of installation. Its accuracy and reliability make this silicon cell pyranometer suitable for monitoring medium-size photovoltaic plants. Key Features:


  • Temperature compensated
  • Two analogic output 0-10V: irradiation and cell temperature
  • Mounting bracket included
