Electronic Vibration Switch
Electronic Vibration Switch Is Designed As Direct Replacement Of Mechanical Vibration Switches.
These Mechanical Switches being used in yester years have very little merit and served the purpose when the requirement was not stringent.
As they rely on large impacts or inertia (both acceleration): they do not respond to gradual increase in vibrations. Nuisance tripping during start-up is an usual problem. Further, sensitivity adjustment is too ambiguous to offer any meaningful translation.
ACD Electronic 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. Built in electronic delay takes care of startup and other spurious signals. Remote reset is another positive advantage.
Either 'Stand Alone' Or 'Remote Sensor' Options are available
These switches can be supplied in enclosures for Weather Proof (IP 65) application or for gas areas
IIA - IIB (Class I, Dvn I Grp. C&D) or IIC (Class I, Dvn II, Grp B)
Some of the applications are Cooling Towers, Centrifuges, Large Motors and Generators, Compressors, Crushers, Naval Vessels etc.
