Working Principle
ZX rotary switch is a level controller for solid materials (including powder, block, granular, gel, etc.). The motor drives the blade to rotate. When the measured medium reaches the blade position, the blade is blocked and stops rotating, thereby triggering the micro switch to output the switch signal. When the measured medium descends away from the blade, the blade returns to the original position and continues to rotate under the action of the spring. The tension of the spring can be adjusted according to the specific gravity of the measured medium, and the spring with the material ratio is adjusted to the strongest, and vice versa.
The rotary switch has been widely used in the chemical, plastic, cement, pharmaceutical, feed, food and other industries.
Features
1, with overload protection to prevent motor damage
2. Good sealing performance, strong overload capability and large output contact capacity.
3. The torque is stable and adjustable. According to the different specific gravity, the sensitivity of the switch can be adjusted by adjusting the tension of the spring.
4, special design blades can be used for low density materials

FAQ
Q: The new magnetic flap liquid level gauge can't show liquid level?
A: 1.check whether there is block in by pass pipe 2.check the the density of medium 3.check whether the float ball is stucked by float ball.
Q: The longest length of magnetic flap liquide level gauge?
A: the length is customized,but in order to be convenient for transport,if the length is over 6m,we recommend
Q: If the float ball is installed at the wrong opposite direction,what's the influence?
A: reading level will be higher than true level,usually higher by length of floatball-70mm
Q: What's installation details of magnetic flap liquid level gauge ?
A: 1.before installation,check specification with label plate. 2.There shouldn't magnetic field within 400m
Q: There is problem in output signal 4--20mA?
A: 1.Check working power supply 2.check wiring 3,check load resistance 4.verify measuring range,zero point
Q: what's specification we need to know before purchasing magnetic flap liquid level gauge?
A: medium density,working temperature,working pressure,material,flange center to center distance,flange standard,whether need 4--20mA output signal;wether need level alarm
