Product Overview
Portable Vibration Monitoring System - Technical Information
IEM’s Portable Vibration Monitoring System (PVS-7500) measures the level
of
ambient vibration in a location. It is extremely accurate and sensitive with very low noise.
Using
an optional attachment, the level of magnetic interference can also be determined.
The PVS-7500 is a purpose-built, “plug-and-play” system. The sensors are fully
integrated and pre-calibrated, so that a user can begin taking measurements almost immediately.
The PVS 7500 is an extremely accurate, ultra-low noise device with excellent linearity. The
extreme
sensitivity ( 1 microinch/sec) of the PVS-7500 permits measurements to guarantee compliance with
Vibration Standard VC-E over the full range from 8-100 Hz in standard 1/3 octave bands. This
capability useful for anyone who needs accurate measurements of ambient vibration, for example,
measuring the vibrations of subway trains passing beneath a research facility or a hospital.
Likewise, the optional magnetometer attachment can measure magnetic energy to determine the
effect a
large electromagnetic body, such as a subway train, may have on surrounding objects. For example
magnetic field measurements are sensitive enough (~0.1 milligauss) to detect the static presence
of
a short subway train 100 ft. below the surface.
