The ZL series master controller is primarily used for setting and controlling the limit positions of the test piece, achieving automatic control of its travel range. Through the reduction function of the worm gear mechanism, it effectively improves control precision.

Due to its advantages such as simple structure, easy installation, stability, reliability, and the ability to arbitrarily set control points as needed, it is widely used in automatic control systems for water conservancy, power, machinery, chemical, textile, food industries, as well as scientific research and meteorology.
