Sensor d'illuminance
A ceiling or wall-mounted lux sensor that measures incident light for cleanroom illumination monitoring and dimming control.
- Cosine-Corrected Lux Measurement
- Low-Profile Optical Head
- 0-10 V or 4-20 mA Lux Signal
- Lighting Control Integration
Introduction de produit
The cleanroom illuminance sensor uses a photodiode and optical diffuser to measure light arriving from a broad field of view. Cosine correction helps the response represent incident illuminance rather than only light perpendicular to the sensor. Range selection covers typical task-lighting and bright inspection environments. A standard analog or digital output supports light-level monitoring, daylight-responsive dimming and alarm reporting while the smooth white housing blends with clean ceilings.
Key Features
Selectable lux ranges preserve resolution in both normal work and high-illumination areas.
Low-profile white construction minimizes visual disruption on clean ceilings.
Analog and network outputs connect to lighting controls and environmental monitoring.
Préoccupations du client produit
Illuminance depends on sensor orientation, shadows and surface reflections, so the measurement point must represent the actual working plane.
A sensor directly under one luminaire overstates the room's average light level.Representative placement and broad optical response reduce local hotspot bias.
Oblique light is under-read by a narrow-angle detector.A cosine-corrected diffuser captures light over a wider incidence angle.
One measurement range saturates in high-intensity inspection zones.Selectable lux ranges match the sensor to ambient or task-light applications.
Dimming causes visible hunting around the target level.Control deadband and time filtering prevent rapid response to small light fluctuations.
