The HZW series gate opening sensor is designed specifically for gate measurement characteristics, utilizing photoelectric or contact encoders, and is manufactured with precision variable-speed mechanisms internally. Its output signals include parallel Gray code, serial RS485, 4-20mA standard analog, and SSI synchronous serial signals, among others, for users to choose from. This sensor is easy to install, highly adaptable, stable, and reliable. It integrates detection and A/D conversion, featuring power-off memory tracking functionality. It is suitable for measuring the lifting height of various gates (such as flat gates, radial gates, miter gates, gantry cranes, bridge cranes, etc.). Its functions, features, and reliability are highly trusted and praised by water conservancy and hydropower engineering technicians.
