All The Accessories You Need To Gather Data On Simulators

SpectraQuest’s simulators are excellent for performing vibration and rotor dynamics experiments and studying typical machinery defects. However, a detailed investigation of a particular phenomenon requires additional tooling and instrumentation. For a convenient one stop shopping, we offer the most frequently tranducers and accessories used when performing machinery fault investigations.

  • Velocity sensors
  • Vibration sensors
  • Proximity probes
  • Stroboscopes
  • Tachometers
  • Motor current probes
  • Shaft alignment kits


These industrial ICP accelerometers have ceramic sensing element of annular shear design in a top-exit, hemretically sealed, stainless steel housing. All of our accelerometers are case isolated and provide excellent resolution and durability in noisy industrial environments.

Proximity Probes

A proximity probe is a displacement transducer, providing an output voltage directly proportional to the distance between the probe tip and the observed conductive surface. It is capable of both static (position) and dynamic (vibration) measurements, and is primarily used for vibration and position measurement applications on fluid-film bearing machines, as well as in speed measurement applications.


A stroboscope is essential in vibration analysis to determine the speed of machinery, for visual examination of moving mechanisms, fault diagnosis, and balancing.


A tachometer is indispensable in vibration analysis to compare actual shaft or rotor speed to vibration spectrum frequencies, locating resonance and sidebands of machinery.

Motor Current Probe

A motor current probe enables Motor Current Signature Analysis (MCSA), which is a useful analysis and condition monitoring technique for the health of induction motors. Through signal analysis, you can perform fault frequency calculation for diagnose problems, such as broken rotor bars, turn-to-turn shorts due to insulation breakdown, single phasing or loss of one phase, phase imbalance, both the static and dynamic eccentricity, and bearing defects.
