What is the difference between relative vibration
Answer Posted / ahmed
In general, the shaft absolute transducer system (which is
shaft vibration relative to space)consists of a relative
displacement sensor and a case-mounted vibration sensor
located in the same external housing. The displacement
sensor is a non-contact sensor measuring shaft position and
movement relative to the case, and the case-mounted
vibration sensor measures case absolute relative to free
space. The two sensors are phase compensated for the
different units and mathematically subtracted to get
absolute displacement of the shaft relative to free space.
