The Portable Vibration Tester TV 7231 is a handheld instrument for measuring and analysing machine vibration, reporting acceleration, velocity, displacement, rotation speed and frequency. Unbalanced, misaligned or worn rotating equipment generates characteristic vibration signatures, and catching a change in those signatures early is what separates a planned repair from an unplanned breakdown. The Portable Vibration Tester TV 7231 gives maintenance teams a portable way to take those readings on the plant floor.
The Portable Vibration Tester TV 7231 carries a low sensitivity probe suited to strong vibration signals, and offers two display modes: a digital value mode and a spectrum mode. Its full graphic 300 x 200 matrix LCD with backlight shows the spectrum chart in real time, and an alarm sounds and switches the unit into spectrum mode when vibration exceeds the set limit, which speeds up diagnosis. Measuring ranges of the Portable Vibration Tester TV 7231 cover acceleration from 1 m/s² to 392 m/s² (peak), velocity from 0.1 cm/s to 80 cm/s (RMS) and displacement from 0.01 mm to 18.1 mm (peak-peak), at an accuracy of ±5%. A large memory holds 100 x 100 measured results plus 100 spectral charts, and RS-232 output sends results to a printer or PC.
Weighing 230 g and powered by rechargeable Li-ion batteries, the Portable Vibration Tester TV 7231 suits condition monitoring of motors, pumps and other rotating machinery. Supplied by BAMR, South Africa's authorised distributor.

When to use the Portable Vibration Tester TV 7231
You are diagnosing rotating machinery in the field and need more than a single overall number. The TV 7231 reads acceleration, velocity, displacement, rotation speed and frequency, and shows results as both digital values and a live spectrum chart.
- 1Spectrum analysis on siteA real-time spectrum chart lets you trace a vibration back to its frequency and likely source rather than only confirming that a level is high.
- 2Alarm-triggered diagnosisAn alarm sounds when vibration passes the limit you set and the meter switches into spectrum mode, so an over-limit reading immediately gives you something to act on.
- 3Stores and prints resultsMemory for 100 testing points with up to 100 readings each, plus spectrum charts, with print and RS-232 output, supports route-based monitoring and record keeping.
