  • Using Your Vibration Condition Monitoring System To Monitor Auxiliary Equipment
    rotational speed such as 1st, 2nd 3rd or 4th harmonic. Some energy may also exist below the 1st order, called the sub-synchronous component. Most energy exists below 1KHz and so standard displacement probes or velocity transducers are generally fitted. The Prosig PROTOR system collects this data
  • Implementing Temperature-Based Variable Fan Speed Control in NLX Power Supplies
    consisting of two pulses per fan rotation. 2. FanC is an input to the NLX-compliant power supply used by the motherboard to regulate fan speed and to shut the fan down. FanC is a 0V to 12V analog signal.
  • Vibration Monitoring Phase Measurement And The Tacho Signal
    Any vibration signal may be analyzed into amplitude and phase as a function of frequency. The phase represents fifty percent of the information so it is most important to measure phase for vibration monitoring. Most vibrations on a rotating machine are related to the rotational speed so
  • PT 104: Cooling Towers and Process Cooler Fans
    provides early warning of machine degradation and impending disaster. In the past, vibration monitoring was a technical challenge due to slow rotational speeds, a variety of support structures, and wet corrosive environments. Mechanical ball/spring vibration cutoff switches were traditionally used
  • The 5 Best Industry Applications For Linear And Rotary Solenoids
    , linear and rotary solenoids can operate in all environmental conditions at extremely high speeds, with an operating life of up to fifty million cycles, and torque ranges that are sensitive enough for medical diagnostic equipment and powerful enough to control industrial automation. 5 Ways Linear
