Product Description

Overview

The HY-CDP22 Photometer measures the level of luminance, or brightness, created by natural light at the tunnel entrance / exit to ensure that the visual perception of drivers will be maintained, both day and night, by avoiding sudden variations in lighting levels and potential “black hole effect” when entering and exiting a tunnel.
The HY-CDP22 Photometer uses a specially designed, highly light-sensitive photocell, filtered to provide a spectral response close to that of the average human eye, to react to changes in light levels within the tunnel environment. This reaction is virtually instantaneous. The light receptor measures the average luminance within an acceptance angle subtending 20 0.
The HY-CDP22 Photometer is a self contained intelligent analyser and the measurements are converted into an output signal of 4-20 mA (directly proportional to the luminance measurement).
The HY-CDP22 Photometer also comes with alarm relay contacts and ModBus serial communications protocol.
The HY-CDP22 Photometer has been designed to enable it to withstand extremes of weather conditions. The complete electronic system is contained within a water-proof, heated housing of powder coated steel with an IP66 protection rating.
The HY-CDP22 Photometer has an operating temperature range from -30‚ - +70‚C which ensures stable readings across all prevailing ambient temperature conditions.
