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) And Does 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 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
Displacement Or Velocity Signal As Per Requirement.
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
