Jeudi 25 juillet 2019 The YOUNG sentry visibility sensor measures atmospheric visibility, meteorological optical range, by determining the amount of lights cattered by particles in the air (smoke, dust, haze, fog, rain and snow). Performance in all weather conditions is achieved with an integrated design that keeps all cabling internal to the sensor for complete protection from hazards. The YOUNG sentry visibility sensor is made from anodized aluminum and rugged, UV-resistant fiberglass enclosures. Based on the proven field experience of the NWS and FAA, the YOUNG sentry visibility sensor uses a “look down” geometry to reduce window contamination and clogging from blowing snow. The optical windows have continuous duty anti-dew heaters. Optional thermostatically controlled external hood heaters are available for additional protection in extreme environments.
All power and signal lines to the YOUNG sentry visibility sensor are protected with surge and EMI filtering to ensure uninterrupted service for the life of the sensor. Installation and maintenance are simple with the YOUNG sentry visibility sensor. A sturdy mounting flange located on the bottom of the main enclosure mates with a user-supplied 1-1/2 inch IPS mounting pipe. Power and signal cables are installed through waterproof cable glands on the bottom of the main enclosure to terminal boards for simple but reliable connections. Calibration of the YOUNG sentry visibility sensor in the field is as simple as attaching a factory supplied calibration fixture and following a procedure that takes less than 30 minutes.
