ZL-II Master Controller Upper and Lower Limit Controller

The ZL-II master controller is primarily used for setting and controlling the travel limits of the test piece, achieving automatic control of its movement. Through the reduction effect of the worm gear mechanism, it effectively enhances control precision.

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