SCHEDULE DEMO
- Provides a spectral response that matches the CIE curve within +/-5% with most light sources
- Sensors are used to measure lighting conditions where the eye is the primary receiver
- Removable sensor simplifies installation and removal of the sensor
Overview
The LI-210R Photometric Sensor measures light with the same sensitivity as a typical human eye. The photometric sensor is ideal for evaluating illumination in work areas, exhibits, interior lighting, and in public spaces.
Mechanics
The LI-210R measures light with a precision-filtered silicon photodiode that is sensitive to light centered in the visible spectrum. It responds to light with sensitivity that is close to the human eye, as described by the International Commission on Illumination (CIE) Standard Observer Curve. Cosine corrected to 82° incident angles for accurate measurements when the light source is not directly overhead.
- Absolute Calibration: ± 5% traceable to the U.S. National Institute of Standards and Technology (NIST)
- Sensitivity: Typically 30 μA per 100 klux
- Linearity: Maximum deviation of 1% up to 100 klux
- Response Time: Less than 1 μs (2 m cable terminated into a 604 Ohm load)
- Temperature Dependence: ± 0.15% per °C maximum
- Cosine Correction: Cosine corrected up to 82° angle of incidence
- Azimuth: < ± 1% error over 360° at 45° elevation
- Tilt: No error induced from orientation
- Detector: High stability silicon photovoltaic detector (blue enhanced)
- Sensor Housing: Weatherproof anodized aluminum housing with acrylic diffuser and stainless steel hardware; O-ring seal on the sensor base
- Size: 2.36 cm Diameter × 3.63 cm (0.93” × 1.43”)
- Weight: 24 g head; 60 g base/cable (2 m) with screws
- Cable Length: 2 m, 5 m, 15 m, 50 m (6.5’, 16.4’, 49.2’, 164’)
- Provides a spectral response that matches the CIE curve within +/-5% with most light sources
- Sensors are used to measure lighting conditions where the eye is the primary receiver
- Removable sensor simplifies installation and removal of the sensor
