Determine Lifting of Shaft using Proximity Sensor
The use of proximity sensor beyond the relative vibration measurement, which is to determine the lifting of the turbine or compressor shaft....
What is Turbine Supervisory Instrumentation (TSI)?
The Turbine Supervisory Instrumentation or TSI includes those measurements which monitor the behavior of the rotor train assembly. These include the speed, vibrations, axial position, and differential expansion of the...
Gap Voltage of Bently Nevada Vibration Probe
Gap voltage (VDC) is a direct representation of distance between the probe’s tip and the shaft’s surface. This is the quiescent voltage that needs to be adjusted between the proximitor’s...
Different Types of Turbine Protective Devices
This article provides the list of different types of Turbine Protective Devices like turbine over speed trip, low lube oil pressure, axial displacement, turbine temperature and turbine vibrations. Turbine Protective Devices...
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...
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....
