Product Overview
Description
SEM228T total solar radiation transmitter 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.
SEM228T 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. Products are widely used in solar energy utilization, meteorology, agriculture, building materials aging and air pollution and other departments to measure solar radiation energy.
