Overview
The CMP11 legacy pyranometer, manufactured by Kipp & Zonen, is an ISO secondary-standard pyranometer that monitors solar radiation for the full solar spectrum range. It connects directly to a Campbell Scientific data logger and is well-suited for meteorological networks and solar-energy research and development. In solar-energy meteorological stations, the CMP11 has been replaced by the CMP10.
Key Advantages
Double glass dome
Technical Description
The CMP11 measures solar radiation with a high-quality blackened thermopile protected by two glass domes. Its flat spectral sensitivity, from 285 to 2800 nm, makes it ideal for applications in natural sunlight, under plant canopies, in green houses or buildings, and inverted to measure reflected solar radiation.
A desiccant-filled drying cartridge prevents dew from forming on the inner sides of the CMP11's domes. Campbell Scientific also offers the CVF4 heater/ventilator that keeps its domes free from ice and dew.
The CMP11 includes a white snap-on sun shield that reduces the sensor's temperature. A bubble level and adjusting leveling screws enable the sensor to be leveled without using a leveling base.
The CMP11 produces a millivolt signal that is measured directly by a Campbell Scientific data logger.
Benefits
- Detector design and faster response make it a step above the CMP6
- Compatible with most Campbell Scientific data loggers
- Integrated bubble level is visible without removing sun shield
- Desiccant-filled drying cartridge prevents dew from forming on the inner sides of the domes
- Compatible with the CVF4 heater/ventilator that keeps the domes free from ice and dew
- Measures reflected solar radiation when inverted
- Provides measurements in direct sunlight, under plant canopies, when the sky is cloudy, and in artificial light
