Accelerometer Mounting Magnetic mounting For special applications where the accelerometer needs to be mounted to ferromagnetic structures for a quick test, one of several Kistler magnetic mounts can be used. The accelerometer is first mounted to the magnet. These mounts can then be moved quickly to measure vibrations at several different locations. Due to the higher mass, industrial magnets are only recommended for measurements of vibrations with frequencies up to 1000 Hz. Further, the added mass may affect the measurement of very light structures due to mass loading. Triaxial mounting Several triaxial mounting cubes are available from Kistler which allow mounting of up to three individual accelerometers in orthogonal directions. The cube's added mass and size must be considered and may affect the overall system frequency response. Kistler also offers integral triaxial units for those applications where mass and size profile are critical. The optimized integral package often provides the best measurement solution. Accelerometer mounting accessories Refer to pages 69 to 71 for details on mounting accessories for Kistler accelerometers. Strain relieving cables Accelerometer cables should be taped or clamped to the same surface on which the accelerometer is attached to avoid motion between the vibration surface and the tie down point. These techniques will prevent flexing of the cable near the connector and thereby minimize any resultant frequency response errors. 12 www.kistler.com
