ES-S228T Thermoelectric global solar pyranometer

ES-S228T Thermoelectric global solar pyranometer adopts the thermoelectric principle and can be used to measure solar radiation with a spectral range of 0.3~3μm. The sensing element adopts a wire-wound electroplating thermopile, and the sensing surface is a black layer with high absorptivity. Using the thermal effect of radiation,Absorb solar radiation and convert it into thermoelectromotive force.

ES-S228T Thermoelectric global solar pyranometer adopts the thermoelectric principle and can be used to measure solar radiation with a spectral range of 0.3~3μm. The sensing element adopts a wire-wound electroplating thermopile, and the sensing surface is a black layer with high absorptivity. Using the thermal effect of radiation,Absorb solar radiation and convert it into thermoelectromotive force. It also has a temperature compensation function, which can accurately measure solar radiation. The double-layer glass cover above the sensing surface can not only reduce the influence of air convection on the device, but also block the radiation of the cover itself. And add a radiation shield to measure scattered radiation.

ES-S228T support standard analog signal or Modbus-RTU 485 communication protocol, which can directly read the current total solar radiation value, and the wiring method is simple. The appearance is beautiful, and the installation space is small.
