3EH-900W resistive material level controller is a rotary micro motor after deceleration, the drive test blades 5-6 rev / min rotation speed.When the test materials increased the leaf material position hindered rotation, thetesting organization will have rotated around the axis displacement. This shift to one of the micro switch operation expected to issue a signal, then another micro switchoperation, cut off electrical power to stop. Unchanged as long as the material level has been maintained such status put. When the material level drop test leaves out blocked,they rely on spring tension testing organizations restore the original state. The firstaction of a micro switch connected to the motor power supply, making it rotate, thenmove to another micro switch no material issue of signal detection as long as theleaves do not block the rotation of the material, such a state will have been maintained.

3EH-900W series resistance rotating material level controller is fully sealed drive swing. Pull the motor base through the spring, when the system is not subject to rent, the motor rotating blades driven testing, testing of materials. Test board is blocked, but still blocked the spindle motor continues to run, pull the motor base spring pressure micro switch, there is expected to issue the signal, and cut off electrical power, the motor stops working, when the material level drops review board loss of resistance, System reset in the spring under tension, micro switch to restore the original state, the motor rotation, also issued material signals. 

Used in metallurgical, chemical, oil, electricity, food, paper, coal, building materials, medicine and other areas of material level alarm and control. High dust explosion-proof and other special environment. 

The new structural design, resistant to corrosion, pollution, moisture, dust; mechanical overload protection device; high temperature ≤ 300 ℃ in the material environment; different proportion of test leaves.
