In this video, we are Explain A transducer that produces a voltage pulse for each turn of the shaft, called the Keyphasor. This keyphasor signal is used primarily to measure rotating shaft speed and serves as a reference for measuring vibration phase lag angle.
It is an essential element in measuring rotor slow roll bow or runout information. The Keyphasor transducer is typically a proximity probe (recommended for permanent installations in which the probe observes a physical gap change event), an optical pickup (used for temporary installations in which the pickup observes a change in reflectivity event), or a magnetic pickup.
