NYZX Rotary Paddle Level Switch Aluminium Oil Seal Design
NYZX ( Sickle Blade )Resistive Level Switch
NYZX Resistive Level Switch Operating Principle
The NYZX series resistive material level switch is a device that uses permanent magnet motor to drive the blade to rotate. When the detected material rises to the blade position, the blade rotation is blocked, and the resistance is transmitted to the detecting device in the junction box. The detecting device outputs a switch signal outward and cuts off the power to stop the blade from turning. When the material level drops, the blade resistance disappears, and the testing device returns to its original state by relying on the spring's pulling force, and adjusts the spring's pull force according to the specific gravity of different materials. When the specific gravity is large, the spring tensile force is adjusted to be strong or strongest. On the contrary, adjust to weak or weakest.
NYZX series resistive level switch is used to detect solid material (powder, particle) level control equipment, widely used in feed, food, pharmaceutical, chemical, plastic, construction, fertilizer and other industries.
