TLUM

LUMINANCE MEASUREMENT

Tunnel Lighting Control System Accessories
TLUM Tunnel luminance sensors provide analog measurement in Candelas per square meter (cd/m²) that target reflected light at each traffic direction’s entrance portal. Long distance signal transmission, up to 4,000 feet is accomplished through a 4-20mA current loop.
