Water conservancy project
Details:

The gate opening meter, also known as the gate opening measuring and controlling instrument, is composed of absolute value type rotary encoder, automatic cable take-up device or other forms of coupler, display, controller, transmission cable, RS485 digital communication interface and other parts. The movement drives the sensor to rotate through the coupler, and then the Gray code encoding signal corresponding to the gate position can be output. It is suitable for the observation and measurement of gate opening of rivers, lakes, reservoirs, ship locks, hydropower stations and water supply and drainage projects.


The gate opening sensor is composed of photoelectric or mechanical series encoders, external mounting brackets, couplings or gears. The sensor connects the ADK encoder shaft with the hoist drum shaft or pinion shaft through couplings and other connecting parts, so that the encoder and the measured shaft rotate synchronously, and the rotation of the measured shaft is converted into the rotation of the encoder shaft. , Collect the encoder value through a special tester to accurately measure the displacement of the DUT. And achieve the purpose of real-time measurement and control of the displacement of the measured part. It is suitable for measuring the lifting height of all kinds of hoisting and screw hoist gates (flat gates, arc gates, herringbone gates, gate cranes, bridge cranes, etc.).


Water conservancy hoist mainly uses multi-turn absolute encoders and pull-wire encoders.
