Now the problem is that Alarm and Trip limits for vibration are set at 5.8 8.9 mm/s RMS and we see frequent alarms due to high peak values of vibration signal transmitted by the probes.

Vibration Analysis

Vibration affects the reliability of a structure or machine, causes damages or failures of the structure or machine. Vibration degrades the human comfort and induces the fatigue and health related problems. Vibration energy is usually dissipated through damping loss and lost in a form of waste heat energy.

What is Vibration and What are Different types of Vibration?,

The diminishing of the vibrations with time is called damping. Shock absorbers, fitted in the suspension system of a motor vehicle, reduce the movement of the springs. when there is a sudden shock. It is usual to assume that the damping force is proportional to the velocity of vibration at lower values of speed and proportional to the square of velocity at high speeds.
