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.

fc number of the low range frequency depends on the fixed number at the time of charging amplifier
Although the sensitivity of the accelerometer varies depending on the frequency of use, we recommend replacing it every 3 years because the sensitivity becomes dull over time.
Low price but high cost-performance! Contributes to more accurate inspections when used in combination with EMIC's vibration testers
EMIC's accelerometers are highly evaluated for their low-price range and high cost-performance compared to other manufacturers' products. In addition, by using it together with EMIC's vibration tester, more accurate vibration measurement can be realized. Depending on which part of and what kind of product you want to measure, we will propose the optimum accelerometer that meets the conditions of each customer.
