SERVICES | MEASUREMENTS

The process of taking measurements is more than operating the sophisticated equipment and collecting data. Details such as where to place the measuring equipment, how many readings to take, at what time intervals to take the readings, conditions that may affect the readings, these factors need to be thoroughly considered prior to measurements to ensure readings taken are relevant and accurate for analysis. This is where technical know-how and experience comes into place.


  • Noise Measurements

    Noise Measurements

    Noise measurement is carried out in various fields. In acoustics, it can be for the purpose of measuring environmental noise, or part of a test procedure using white noise, or some other specialised form of test signal.
  • Vibration Measurements

    Vibration Measurements

    Vibration is a time-based (periodic/cyclic) displacement of an object around a center static position. The following contributing factors have a complex relationship with the magnitude and rate of the vibration:
    • The object’s own natural frequencies and stiffness
    • The amplitude and frequencies of any external energy source(s) inducing the vibration
    • The coupling mechanism between vibration energy source and the object of interest.
    Vibration measurement is complex because of its many components – displacement, velocity, acceleration, and frequencies. Also, each of these components can be measured in different ways – peak-to-peak, peak, average, RMS; each of which can be measured in the time domain (real-time, instantaneous measurements with an oscilloscope or data acquisition system) or frequency domain (vibration magnitude at different frequencies across a frequency spectrum), or just a single number for “total vibration.” Vibration measurement is sometimes used as an indirect measurement of some other value. The final measurement goal determines the approach to the measuring vibration. Often, condition monitoring– predicting or monitoring wear, fatigue, and failure – requires vibration measurements meant to determine the kinetic energy and forces acting upon an object . This is often called inertial vibration. Monitoring machinery motors (especially the bearings) in critical applications is an example. In these cases, the measurement of acceleration provides an easy conversion to units of force assuming the mass of the object is known.
  • Commissioning Measurements

    Commissioning Measurements

    The finishing touch to the design and build, where readings / measurements need to be taken while the machinery or system undergo operational conditions. This is to ensure that the machinery or system can survive the “test” and thereafter, be commissioned to be fully capable of performing at its intended capacity and ability.
