ACD Machine Control Co Pvt Ltd is a Mumbai-based manufacturing company specialised in indigenously developing and manufacturing equipment in the field of vibration and wind monitoring systems.

Electronic Vibration SwitchElectronic Vibration Switch by ACD Machine Control is designed as direct replacement of mechanical vibration switches. These mechanical switches being used in yesteryears have very little merit and served the purpose when the requirement was not stringent. As they rely on large impacts or inertia (both acceleration) nuisance tripping during start-up is a usual problem.

ACD vibration switches can be directly installed in place of mechanical vibration switches and offer immense advantages. The basic sensor is piezo electric accelerometer which has no moving parts. These electronically integrate the acceleration signal giving velocity signal. Vibration could be controlled very precisely with graduated controls. The built in electronic delay takes care of startup and other spurious signals. Remote reset is another positive advantage of using ACD vibration switches. Some of the applications of these switches include cooling towers, centrifuges, large motors and generators, compressors, VSI crushers, naval vessels etc.

Wind Velocity MonitorThe Wind Velocity Monitor designed by ACD is a result of by some serious crane accidents during erections 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 a failure of components or turning over of the crane. In case of negligence, definitely there is a risk to life.

The crane operator must be given sufficient warning to decide when the crane should be put out of service because of risks due to high winds and his inability to control the load. It is likely that many fatalities could have been avoided with proper wind condition monitoring.

ACD’s wind velocity monitor continuously monitors wind speed and provides two limit switches with one changeover relay contact per setting. The bright display allows the user to note the readings in poor light condition also. The panel has provision to set the ‘Alarm’ and ‘Danger’ limits (settable over full range) with one change over contact. The other products by ACD include dynamic balancing machines, portable anemometers, wind data loggers, vibration data loggers, vibration meters.
