ACD wind velocity monitor continuously monitors wind speeds and is a very useful device for ensuring the safety of tower and crawler cranes.
ACD’s Wind Velocity Monitor/Switch was prompted by some serious crane accidents during erection of tall constructions where wind conditions appear to have been a major contributing factor. The operation of a crane without knowledge of the expected wind forces can lead to failure of the components and/or tilting over of the crane. The crane operator must be given sufficient warning to decide when the crane should be put out of service because of the risk posed by high winds and his inability to control the load. Many fatalities could have been avoided with proper wind condition monitoring.
The wind velocity monitor continuously monitors wind speed and provides two limit switches with one changeover relay contact per setting. Bright displays allow the operator to note the readings in poor light conditions. The panel has provision to set the alarm and danger limits (settable over full range) with one changeover contact.
ACD vibration switches can directly be installed in place of mechanical vibration switches and offer many advantages.
Our electronic vibration switch is designed as a direct replacement of mechanical vibration switches. Mechanical switches have very little merit and do not meet the current stringent requirements since they rely on large impacts or inertia during acceleration, and tripping during start-up is a common problem in the machines.
In the ACD electronic switches, the basic sensor is piezo electric accelerometer which has no moving parts. These electronically integrate the acceleration signal, giving velocity signal. Vibration can be controlled very precisely with graduated controls. Built-in electronic delay takes care of start-up and other spurious signals. Remote reset is another advantage. Some of the applications are Cooling Towers, Centrifuges, Large Motors and Generators, Compressors, VSI Crushers, Naval Vessels etc.
Besides specializing in indigenously developed Vibration and Wind Monitoring Systems, we also provide Dynamic Balancing Machines, Portable Anemometers, Wind Data Loggers, Vibration Data Loggers, and Vibration Meters.
