TM 150.20 System for data acquisition




  • Measurement and illustration of frequency and phase response
  • Digital storage oscilloscope


Technical Description

This system for data acquisition is an addition to the TM 150 vibration trainer and makes it possible to analyse vibration signals on a PC. Frequency and phase response curves can be easily generated, saved and output using this system. The system also offers all the essential functions of a digital storage oscilloscope and can calculate the frequency spectra of the signals.

In addition to the software, a displacement sensor and a reference sensor, the system also includes an interface box. This supplies up to three sensors, prepares their measuring signals for the PC and offers them to three analogue outputs for display.

All components of the system are ready at hand and securely housed in a storage system.

Learning objectives/experiments

- supported experiments with TM 150
-- natural vibration of a bar-type oscillator
-- damped vibration of a bar-type oscillator
-- forced vibration of a bar-type oscillator (damped and undamped resonance)
-- frequency and period time measurements
-- Kater's pendulum
