LUMINANCE METER
The DURLUM420 analog sensor measures the luminance (cd/m2) of a surface and converts it into a current loop signal.
The 4-20mA signal output is supplied by the same power supply cable, offering easier cabling on installation.
It is based on a Si photo-sensor, that offers a sensitivity close to visible light and a stable behavior.
High protection grade for the outdoors and solid stainless steel construction.
