  • Vibration Proofing Metal Foil Resistors
    Circuitry for space probes, avionics. and down-hole data logging must. perform flawlessly under harsh. conditions, including high vibration. and extreme temperature changes. Even a failure of a minor component. can negatively impact-or stop-the. performance of the entire device. For. instance
  • Using Your Vibration Condition Monitoring System To Monitor Auxiliary Equipment
    The use of a vibration condition monitoring system for monitoring vibration from large rotating machines fitted with fluid-filled journal bearings such as steam or gas turbines is well understood. Vibration from these components generally falls within the main harmonics or orders of the shaft
  • Huygens Probe and PAT: Exploring a New World
    colder than an average laboratory. We persist in trying to use instruments designed for an air-conditioned, vibration-free laboratory in a busy industrial plant. We persist in accepting laboratory levels of reliability that have no place in a manufacturing environment. We persist in accepting complex
  • Shaft Displacement Measurement Using A PROTOR System
    Shaft displacement is an important vibration measurement for rotating machines. Shaft displacement is usually monitored by non-contact shaft displacement probes such as eddy-current probes. These probes produce a voltage proportional to the distance of the shaft surface relative to the tip
  • Spectral phase shaping for high resolution CARS spectroscopy around 3000 cm-1
    By spectral phase shaping of both the pump and probe pulses in coherent anti-Stokes Raman scattering (CARS) spectroscopy, we demonstrate the extraction of the frequencies of vibrational lines using an unamplified oscillator.
  • How Does a Sonicator Work? (.pdf)
    The ultrasonic electronic generator transforms AC line power to a 20KHz signal that drives a piezoelectric convertor/transducer. This electrical signal is converted by the transducer to a mechanical vibration due to the characteristics of the internal piezoelectric crystals. The vibration
  • Understanding And Caring For The Heart Of Your Ultrasonic System
    energy (or heat) at the contact point of the two parts. The heat melts a molded ridge of plastic on one of the pieces and the molten material flows between the two surfaces. When the vibration stops, the material solidifies forming a permanent bond. A basic ultrasonic probe consists of -. 1. A housing
  • Resistance Temperature Detectors RTD
    ACROLAB RTD assemblies utilize wire wound platinum elements with a reference resistance of 100 Ohms at 0 C and a temperature coefficient of 0.00385 Ohms/Ohm/C degrees. ALL Acrolab RTD probes are of the "filled tube" or "MGO" construction, providing long operating life in high vibration
  • Spiralock Fasteners Make Descent to Saturn's Largest Moon
    After a seven-year, two billion mile journey strapped to the side of the Cassini orbiter, the Huygens probe decelerated 12,000 mph in less than two minutes, before parachuting to the frozen surface of Titan, Saturn's largest moon, on Jan. 14th this year. Besides measuring wind, pressure
