SR20-D2-05 Hukseflux - Cảm biến bức xạ mặt trời SR20-D2-05 Hukseflux Việt Nam

Best pyranometer for the PV industry SR20-D2 is the most accurate digital secondary standard pyranometer available. Its benefits:

Digital output: easy implementation & servicing
Best-in-class temperature response, < ± 0.4 % (-30 to +50 °C), best  “zero offset a” and best calibration uncertainty
Test certificates for temperature response and directional response included as required by ISO 9060
Re-calibration registers fully accessible to users
In order to improve overall measurement accuracy, Hukseflux effectively targeted two major sources of measurement uncertainty: calibration and “zero offset a”.
In addition, SR20-D2 has a negligible temperature response. All are best in class. The temperature response of every individual instrument is tested and corrected onboard by the instrument electronics, using a second degree polynomial. SR20-D2’s low temperature dependence makes it the ideal candidate for use under very cold and very hot conditions.

SR20 pyranometer meets ISO 9060 class A requirements
SR20-D2 pyranometer design
The pyranometer employs a state-of-the-art thermopile sensor with black coated surface, two domes and an anodised aluminium body. The connector, desiccant holder and sun screen fixation are very robust and designed for long term industrial use. SR20-D2 uses a high-end 24-bit A/D converter. All parts are specified for use across SR20-D2’s entire rated operating temperature range. SR20-D2 offers two types of outputs commonly used in the solar PV industry: digital output via Modbus RTU over 2-wire RS-485 and analogue 4-20 mA output (current loop).
