ESD(Emergency Shutdown ) System

                 ESD shutdown is required to perform a safe process shut down (trip) if any of the unsafe conditions occur .

                  By the safety standard IEC 61508 the functions of an ESD and a process control system cannot be shared -- the safety system must be separate.

What is vibration?

                                     Mechanical vibration is the dynamic motion of machine components.

                            Vibration measurement is the measurement of this mechanical vibration relative to a known reference. In metric units peak to peak vibration displacement is usually expressed in microns,

            one micron equals one thousandth of a millimeter (0.001 mm).

            It is sometimes expressed in mils, where 1 mil = 0.001 inch
