Comparing Vibration Readings
Comparing vibration level readings taken by different types of instruments and transducers can be very confusing and can lead to mistrust of the systems involved. Knowledge of how to prop
Diagnostic Techniques-Part 3
Transient analysis is the study of how various signals change during a machine's process or load change. This analysis is particularly important during a machine's startup or shutdown when critic
Differential/Rotor Expansion
Differential Expansion (DE) and/or Rotor Expansion (RE) are very important measurements usually supplied by the Original Equipment Manufacture (OEM) as part of a Turbine Supervisory Instrumenta
Proximity Probe Transducer Installation: Part 1 Radial Vibration
Proximity Probe Transducers (Proximity Probes) are the vibration transducer of choice when installing vibration monitoring on Journal Bearing equipped rotating machinery. Proximity
Diagnostic Techniques-Part 2 Frequency Domain
Frequency domain measurements and analysis have become increasingly popular to diagnose a particular machine fault. This measurement mode relies on processing the transducer output signal using F
Shell or Case Expansion
Shell or Case Expansion is a very important measurement as part of a Turbine Supervisory Instrumentation (TSI) System for large steam turbines. This measurement should be included in turbine retr
Valve Expansion
Valve position measurements are an important aspect of a complete Turbine Supervisory Instrumentation system. Typically, the Main Steam Control (or Throttle) Valve is always included
Turbine Supervisory Instrumentation: Shell or Case Expansion

Tech Note 101: Wiring CMCP1100 (ICP) Accelerometers
CMCP-1100 Industrial Low Cost Accelerometers are of the “ICP” type, which are the Industry Standard. All ICP accelerometers are powered using a CCD or “Constant Current Diode” between 2 and 10 mA. Po
Tech Note 103: Accelerometer Powering with CCD Diode
When connecting a CMCP525/530 Transmitter to a Accelerometer that is already powered by another device the CCD (Constant Current Diode) should be cut to prevent overpowering of the Accelerometer by c
Tech Note 105: Reversing Normal Thrust Direction CMCP545(A)
CMCP545(A) Transmitters and Monitors ship standard with "upscale towards probe". To change the upscale direction on a CMCP545 from normally towards the probe to normally away and where the range opti
