The CMP 11 pyranometer from Kipp & Zonen uses the same temperature compensated detector technology originally developed for the CMP 22 and offers a step up in performance from the CMP 6. The reduced response time of 1.66 seconds (63%) meets the requirements for solar energy applications and is particularly suitable for meteorological networks.
A waterproof socket is fitted for the signature yellow signal cable, which is available in a range of lengths pre-wired to the waterproof plug.
The integral bubble level is raised to the top of the housing allowing it to be viewed without removing the redesigned snap-on sun shield, which also covers the connector. The connector has gold-plated contacts allowing for easy exchange and re-calibration. The screw-in drying cartridge is also easy to remove and the replacement desiccant is supplied in convenient refill packets.
The Pyranometer does not require any power, it supplies a low voltage of 0-20 mV in relation to the amount of incoming radiation. When a higher voltage level or a 4-20 mA signal is required, the AMPBOX is the perfect solution.
