The vibration transducer TRM100 is an accelerometer based on micro-electro-mechanical-systems (MEMS) technologies, designed for vibration monitoring with the handheld instrument SPM VibChecker. The transducer has integral magnet for attachment to plain, clean metal parts with the main sensitivity axis pointing in the desired measuring direction. To get comparable results, measuring points should be clearly marked, so that the measurements can always be taken in the same spots.
