EMIC's accelerometers, the key to vibration testers, quantify vibration.

THAI EMIC CO.,LTD.

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.

Accelerometers

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.

541-DSH：For temperature vibration measurement and control

エミック加速度センサ541-DSH

・ Maximum measured acceleration (sign):-
・ Maximum measured acceleration (shock): 16000 m/s2 0-p
・ Measurement frequency range *: fc to 5000 Hz
・ Mounting resonance frequency: Approximately 27 kHz or higher
・ Operating temperature range: -20 to +250℃
・ Mass: 35 g
・ Charge sensitivity: 5.0 pC/(m/s2)±25％
・ Capacitance: 1000 pF±25%

* 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.
