Climatronics - Illumination Sensor - Out Light Monitor
Photometry refers to the measurement of visible radiation (light) with a sensor having a spectral responsivity curve equal to the average human eye. This curve is known as the CIE Standard Observer Curve (photopic curve). Climatronics` photometric sensor (P/N 101668) is used to measure lighting conditions where the eye is the primary receiver, such as illumination of work areas, interior lighting, television screens, etc. The sensor utilizes a filtered silicon photodiode to provide a spectral response that matches the CIE curve within ±5% under most light sources. This photodiode and filter combination is placed within a fully cosine-corrected sensor head to provide the proper response to radiation at various angles of incidence.
Other applications of Climatronics` Photometric Sensor include interior and industrial lighting, outdoor illuminance, passive solar energy, architecture and lighting model, illumination engineering, and biological sciences. The 101668 is a research grade photometric sensor that is very reasonably priced.
The illumination sensor is easy to use. It can be directly connected to a voltmeter or a data logger, such as Climatronics` IMP-850/IMP-860 series data loggers. Direct readout in Lux (Ix) can be derived from the measured voltage divided by the calibration coefficient.
