RAMSES G2
Hyperspectral Radiance and Irradiance Sensors for the UV, VIS or UV/VIS range.
RAMSES radiometers are spectral imaging radiometers to measure radiance, irradiance, or scalar irradiance in the UV, VIS and UV/VIS ranges. Thanks to their ultra small size and weight as well as very low power consumption, they are especially suitable for hand-held and autonomous applications. RAMSES radiometers combine precision hyperspectral light measurements with a maximum of flexibility. The modular system increases cost-effectiveness, while the many accessories and special solutions enable a wide range of applications such as installation on ships, handheld usage or autonomous measurements in remote places, like the Arctic or Antarctica. By implementing the G2 extension module, the RAMSES radiometry series now also features the innovative G2 Interface and can now easily be configured by using a web-browser. The internal data logger with 2 GB storage and the comparably low power consumption provides the opportunity for a self-sufficient measurement operation without a separate controller. The addition of the Modbus RTU protocol to the interface simplifies the integration into existing PLCs and external data loggers. Additional to radiance and irradiance, the parameters inclination, pressure and temperature can be retrieved. |
