-Working principle:
The SGR4 long wave radiometer is a high-quality scientific measurement instrument. The specially designed meniscus dome provides a 180 ° field of view, allowing for negligible directional response errors. The hard carbon coating on the outer side of the dome can smooth out the spectral response and provide additional protection for the silicon surface. The excellent thermal stability of the dome structure and coupling to the instrument body eliminates the need for dome temperature measurement or dome shielding. SGR4 can be set through the CVF4 ventilation unit to further improve its performance.
The internal desiccant of SGR4 can last for at least 10 years. This can reduce maintenance costs. By using SGR4 with CVF4 ventilation unit, the cleaning interval of the dome can be extended, and the measurement quality can be improved. SGR4 has a Modbus interface, enhanced analog output, improved response time and temperature correction measurement data. Long wave networks and downward radiation can be directly obtained through Modbus. The power supply range is from 5 to 30VDC, suitable for the integration of meteorological and solar power plants. The SGR4 is very powerful and comes with a 5-year warranty (*).
