Campbell outlines a blueprint for a world class maintenance program by examining, piece by piece, its essential elements - leadership (strategy and management), control (data management, measures, tactics, planning and scheduling), continuous improvement (RCM and TPM), and quantum leaps (process reengineering). He explains each element in detail, using simple language and practical examples from a wide range of industries.

EVOLUTION multi sensor system is a digital, battery-powered instrument which has interchangeable Sensor Modules. A common Display Unit recognizes any Sensor Module and configures the Display without programming or set-up. The unit can be configured as a Laser Tachometer, Contact Tachometer, Dual Contact Thermometer, Humidity/Thermometer, Infrared Thermometer or a LED Strobelight

The Stress Tel family of "T-Mike" Ultrasonic thickness gages are compact, rugged, easy to use instruments for determining thickness of metals, plastics, ceramics, glass or virtually any other material which conducts ultrasound.

The SPM LUBECHECKER allows you to properly lubricate your bearings. The instrument works according to the SPM method. It monitors the shock pulses from the bearing and indicates the effect of the fresh lubricant on the oil film inside the bearing. Instead of assuming that your bearings are properly lubricated, you can immediately watch the result.

The VIB-10/11 is a hand-held instrument for measuring the RMS value of vibration velocity, to detect out-of-balance, misalignment and other mechanical faults in rotating machines. The VIB 10/11 is sturdy, battery powered, and easy to use.

Thrust Position Measurement

Thrust Position Monitoring was one of the earliest applications for Eddy Current Transducers. When utilized for this application, it is one of the most important components of a complete machinery protection system.

Thrust bearing failure produces one of the most catastrophic failures of a rotating machine. This could result in very expensive repairs and the possibility of machine replacement.

Theory of Operation

Eddy Probe Transducers work on the proximity theory of operation. A System consists of a matched component system: a Probe, an Extension Cable and an Oscillator /Demodulator. A high frequency RF signal @ 2 mHz is generated by the Oscillator/Demodulator, sent through the extension cable and radiated from the Probe tip. Eddy currents are generated in the surface of the shaft. The Oscillator /Demodulator demodulates the signal and provides a modulated DC Voltage where the DC portion is directly proportional to gap (distance) and the AC portion is directly proportional to vibration. In this way a Eddy Current Transducer can be used for both Radial Vibration and distance measurements such as Thrust Position and Shaft Position.
