Special Accelerometers

This page shows vibration sensors for special applications.
The Seat Pad Accelerometer Model KB103SVD was developed for measuring whole body vibration transmitted by driver seats of building machines and other vehicles in compliance with ISO 10326-1 and ISO 7096. The sensor has an IEPE output for robust signal transmission.
The Probe Accelerometer Model KST94 was developed for automated vibration testing in a mass production process. The sensor features a movable tip. It can be approximated to the test object, for example, by pneumatic force. A sophisticated damping system provides excellent reproducibility and suppression of environmental vibration. Model KST94 has an outstanding life expectancy of over 10 million test cycles. Its IEPE output can be processed by standard equipment, for instance the M33 signal conditioner or M12 vibration monitor.
The Low Power IEPE Accelerometers KS94L and KS943L are intended for applications demanding low power consumption, such as telemetry or other battery powered equipment.
Model KS82L has an integral magnetic base with a center contact for reading digital serial numbers from VMID measuring points.

Calibration adapter for KST94
Application Example:

Vibration Testing at Motors, Gear Boxes etc. in Production Plants with KST94 and VM-FFT+

Anwendungsbeispiel

  • The KST94 with its movable tip can be automatically pressed against the test object by pneumatic force.
  • By its internal vibration isolation the KST94 can measure precisely even in noisy environments.
  • An M302 USB sensor interface samples the data.
  • By the software VM-FFT+ the measuring signal is displayed in frequency domain. Measurement can be triggered via a digital input.
  • An arbitrary limit curve allows frequency-selective alarms which can be transmitted, for example, by the industrial switch modules of ADAM series.
