PE employs a suite of field transportable, state of the art, vibration test instrumentation to measure and record vibration waveforms. Post processing allows easy analysis of transient data in the form of Bode and Nyquist plots, as well as spectral and orbit plots for steady state data. Vibration is routinely measured with a host of transducers as appropriate, including accelerometers, seismic transducers, proximity probes, strain gages, and piezometers. PE has extensive experience in both the theoretical aspects of vibration analysis and the practical considerations of proper transducer mounting, instrument grounding & shielding, etc. required to produce valid data for subsequent analysis.
