Rotary WAM WAM material level alarm Rotary material level alarm works utilize permanent magnet motor drives the blades rotate, the material to detect when the blade was raised position, the blade rotation is blocked, the resistance of the junction box is passed to the detector through the shaft means for detecting the device is outside the output signal of a switch and cut off electrical power to make the blades stop turning. When the material fall, leaf loss of resistance, the detection device will depend on spring tension restored to its original state, restore the blade rotation state. Large difference in specific gravity for the use of materials, adjustable spring tension, heavy spring tension when adjusted to the strongest, otherwise adjusted to the weakest. WAM Rotary material level alarm has the following features: 1. Shell whole airtight, waterproof and dustproof performance. 2. Fully sealed bearings, plus a special seal to prevent infiltration of dust along the shaft. 3. adjustable spring tension can be adapted to measure a variety of bulk density materials. 4. Unique clutch design, with overload protection. 5. Installation is simple, and does not have to be removed from the warehouse wall, you can check, replacement of internal parts. WAM material level signal installation requirements: 1. In the coupling position φ60mm hole cut to the hoop insert 1/3 screw connection, welding solid 2. Level the instrument insert and tighten the screw clamps must be enabled and outlet down, then Mother with back fastening wiring diagram. WAM Rotary material level alarm for fixed measurement silo material level, it has anti-adhesion, high temperature, adjustable sensitivity characteristics. WAM Rotary material level alarms installed at the bottom or top of the silo, enabling short positions or warehouse full of alarm, or at some distance (about 1 meter) to install one, you can estimate the silo material level, but also with access to interlocked feeding equipment, automatic start and stop conveying equipment to achieve the purpose of automatic control system, if applied to the computer ingredients, you can greatly improve product quality, increase production efficiency. WAM Rotary material level alarm is mainly used in modern industrial processes and warehousing sectors, powdery and granular materials used for container, were material level detection or control. After its working principle is to use the AC micro-motor through reducer, drive slow rotation detection blades, when the material level rise measured materials. When the cause of the rotor blade being blocked, testing organizations around the spindle will generate rotational displacement, this displacement is not the first to make a switch action. There are expected to issue a signal, and then another micro switch operation. Cut off the power to stop micro-motor rotation. As long as the material level positions remain unchanged, this state has been maintained. WAM Rotary Level alarm when the material level falls and the detection of the loss of barrier blades, testing agencies will rely on spring tension recovery state. First, a micro switch operation. Turn on the motor to rotate. Subsequently, another micro switch operation signal no material issue. As long as there is no material to block rotation detection blade. This state has been maintained.
