NYZX ( Flat 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.

NYZX Resistive Level Switch Installation requirements
- Confirm material specific gravity to select blade.
- Confirm installation method and size.
- Please choose the high temperature serieswhen the temperature in the barrel is over 80°C.
- Stop switch junction box outlet must be down, cable fixed screw mother must be locked.
- When the continuous position is 1 "thread, the sickle blade can be selected so that it can be locked directly into the tube tooth.1'
- The controller can be installed at ahorizontal angle of 15°C-20°C to reduce the impact on the material.
- Shaft length adjustable type and steel cable type only suitable for top mounting.
- The rotary resistance switch should avoid being installed directly under the blanking opening.
- When there is no way to avoid it, a steel plate can be welded on the top wall of the product to reduce
- the impact of the material product and prevent the material impact from causing misoperation.
- The torsion spring is used to adjust the output torsion of the rotating shaft. When the specific gravity of the
- measured object is large, the spring torsion can be adjusted to the strongest position, but the blade sensitivity is
- poor. On the contrary, the smaller the specific gravity of the measured object, the weaker the spring is, and the better the blade sensitivity is. (Note: The force of the torsion spring should not be replaced at will so as not to make a mistake).

NYZX Resistive Level Switch Application Field
NYZX series resistive level switches are installed in silos, boxes,
cellars and shafts, which can be used to control filling height and
fill, empty, and protect against overloading. Widely used in feed,
silica, stone, globular particles, sawdust, calcium powder, rubber,
metal, malt, limestone, grain, foundry sand, sawdust, NYZX series
resistive material level switch, with its perfect combination of
durability and sensitivity, has been praised by users all the time,
and stands out among many manufacturers of resistive rotary switch.
