Accelerometers are indispensable for accurate data acquisition in vibration tests. Acceleration is the rate of change of velocity per unit time, and acceleration is always applied when the velocity of an object changes. It is a sensor that detects their size and quantifies gravity, movement, vibration, impact = vibration of objects.

EMIC offers a wide range of accelerometers that can handle a variety of vibration measurements, from ultra-compact / lightweight high-precision vibration measurement to special 3-way simultaneous vibration measurement, earthquakes, and vibration measurement and analysis of building structures. In this article, we will introduce the lineup of accelerometers handled by Thai EMIC and their strengths.

EMIC’s accelerometer (acceleration pickups) sold in Thailand

There are 12 types of accelerometers made by EMIC, and 4 of them are available in Thailand. These are key devices for vibration tests, and are installed in all vibration testers.
