Measuring transducer of illumination/luminance MPLx is a device which turns the amount of incident light into analogous measuring signal.

             It is possible to apply the device for various purposes, and it is produced especially for controlling the tunnel adaptation zone lighting. It is produced for various measuring scales, by type or upon request. Standard is 4 - 20 mA = 0 - 60 kLux. The device gives a measuring signal over analogous output 4 - 20 mA which is an input signal for the device which controls the lighting (el Reg - PRO-CT).   

 

             A-device MPLx is outline without optics, the sensing diode converts total incident light (approx. 180^o). The top cover incorporates a half-sphere disperser. The device may be mounted in any position (elevation).

             B-device MPLx is a device with view-angle blend 20^o

 optics for measuring tunnel entrance luminance with an integrated opening display of  20^o.

 

Wiring is two-wire 0,4 mm2. The device is prepared for mounting on console or pole with separate cable-box.
