LUX Sensor 200K
LUX200K Sensor for measuring the illuminance (lux), defined as the ratio (lumen) between the light passing through a given surface and the surface area (m2 ). Ideal for illuminance measurements in indoor or outdoor, with degree of protection IP67, ideal for offices and laboratories, industrial buildings, shopping centers, theaters, museums, sports facilities, roads, tunnels, nursery-plant, etc. Quality instrument that, thanks to the different types of standard electrical output ( 0-10v voltage and 4-20mA current) or digital RS485 with ModBus (optional MCS), can be easily interfaced with any acquisition system. Each instrument is supplied with a calibration report. The sensor features excellent cosine response, which ensures accurate measurements under diffuse light and when sunlight originates from a low solar angle. This, in combination with high resolution at low light levels .
- Uniform sensitivity for accurate measurements outdoors, under vegetation, or in artificial lighting without changing the calibration.
- Customized Optical filter tailors the spectral response to an unprecedented performance standard.
- Weather resistant and durable in high-temperature, high-humidity, long-term deployments.
- Cosine correction is accurate even when the light source is not directly overhead.
- Easy installation, removal, and recalibration.
The lux meter measures the illuminance (lux) definite as the luminosity ratio (lumen) that cross a surface and the surface area considered (m2). The sensor is made of a silicon photodiode and of a high accuracy electronic device able to convert the radiometric size of illuminance in a normalized electrical signal that can be acquired by whatever datalogger. The spectral response curve of transducer is equal to the human eye response curve, known as photopic standard curve V () Calibration of the sensor Each instrument is calibrated and verified by comparison with a primary instrument with known constant. In this way is determined the constant of the sensor to be calibrated.
