HSW Mechanical Display Float Level Sensor

The HSW float-type water level sensor (with water level display) is a digital sensor that integrates mechanical and electrical technologies. It converts the angular displacement of the output shaft into corresponding digital quantities, enabling high-precision measurement of the liquid level height and accurate position confirmation. It features a power-off memory function.
