What is Keyphasor ? How does Keyphasor works ?
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

Vibration Measurement
Proximity Transducer System Operation
Proximity Transducer System provides an output voltage directly proportional to the distance between the probe tip and the observed conductive surface. It is capable of both static (position) and dynamic (vibration) measurements, and
Mechanical Vibration Switch Principle
Mechanical Vibration Switches provide vibration protection for low- to medium-speed machinery. An inertia sensitive mechanism activates a snap-action switch with SPDT output contacts if the vibration exceeds an adjustable setpoint.
Non-contact Vibration Measurement
Types of Non – Contact Vibration Measurement Path Measurement Capacitance Eddy Current Hall Effect Optical Speed Measurement Laser-Doppler vibrometer Seismometer Acceleration measurement Path measurement Capacitive Principle The capacitive principle can
Contact Vibration Measurement
Types of Contact Vibration Measurement Path Measurement Potentiometer Type LVDT Type Speed Measurement Electrodynamics Seismometer Acceleration measurement Piezoelectric sensor Piezo-resistive sensor Resistive sensor Inductive sensor Path Measurement Potentiometric Transmitter The
Accelerometer Vibration Probe Principle
In simple language we say that vibration is a movement or mechanical oscillation about an equilibrium position of a machine or component. Vibration is a by-product of an otherwise useful
Speed Probe Working Principle
Rotating machinery requires speed sensing for functional systems such as control, monitoring, and safety. To ensure safe operation, it is especially important to monitor rotor speeds in turbine engines. Inductive
Bently Nevada Vibration Probes Functional Testing
Bently Nevada Vibration Probes Functional Testing Objective : To check the characteristics and healthiness of vibration probes ( make : Bently Nevada ) Principle: Proximity transducers use Eddy Current principle to
What is TK-3 Calibrator ?
TK-3 Calibrator instrument provides a reference mechanical motion for calibrating and performance testing of machinery protection systems. The two models of the instrument have identical functions but different power sources.
