After bin XL-1 resistance rotary level control device is AC micro-motor through reducer, drive slowly rotating blade detection. When the material level rise measured material by blocking the rotating blades, the testing organization will produce around a spindle rotational displacement. This displacement of the first of a micro switch operation, there is the material of the signal is issued. Then another micro switch to cut off power to stop micro-motor rotation. Level signal is mainly exposed material components, are stainless steel and aluminum components. Resistant to corrosion, pollution, moisture, dust and other characteristics, the food industry or high dust environments can be used slightly evil; the output shaft with a overload protection device can effectively avoid the use of improper or abnormal forces on the motor and reducer damage caused; according to user needs is available in two different installation methods, to meet a variety of different materials to facilitate the use of gravity adjustment. XL-1 resistance rotary level control instrument technical parameters: Motor Power: 220VAC 50Hz 110VAC 50Hz (specify when ordering) blade speed: 1RPM rated power: 3W measure torque: 0.5 ~ 1.0Kg.cm junction capacitance: 5A / 250VAC applicable gravity: 0.5g / cm3 of protection: IP54
