PHP-FB Wind Speed Alarm DeviceOverview

PHP-FB Wind Speed Alarm DeviceComposed of a microprocessor and a wind sensor with high dynamic characteristics, it can observe the instantaneous wind speed in the atmosphere, as well as the two minute and ten minute average wind speeds. It has wind speed alarm setting and alarm output control functions;PHP-FB Wind Speed Alarm DeviceAdopting dual screen display output, the wind speed display adopts high brightness LED digital tube display, with a long observation distance and suitable for use in low light and at night. The parameter settings adopt graphic LCD display, with a user-friendly human-machine interface;Equipped with sound and light alarm, the wind speed exceeding * alarm emits sound and light alarm to remind operators to pay attention to safety, and also generates a relay switch output. The instrument adopts a wall mounted waterproof box, which is easy to install, occupies small space, and has high reliability. The characteristics of the instrument are light weight, easy installation and use, accurate wind speed measurement, and intuitive and clear digital display. It is a wind speed detection instrument that ensures the safety of operation for large and medium-sized building tower cranes, lifting machinery, hanging baskets, and cable cars.

According to the technical requirement 4.1.2.1 of the "Tower Crane Design Specification Standard JB9462-88" issued by the Ministry of Construction, the wind speed should not exceed 20m/s when working at the maximum installation height of the crane. The overall installation climbing or jacking operation wind speed shall not exceed 13m/s. ”According to Article 4.5.6, for cranes with a total intersection point of more than 50m at the base of the boom, an anemometer should be installed at the top. ”(2) The Tourism Bureau has designed and manufactured the regulations on the operation of passenger aerial ropeways in abnormal weather conditions, which stipulate that the operation must be stopped when the maximum instantaneous wind speed exceeds 15m/s.
