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
