Product Overview

In construction, bridge, dam and geological research projects, many critical vibration signals are weak low-frequency vibrations. These vibrations have small amplitudes and extremely low frequencies, making them difficult to capture with ordinary accelerometers. Such applications impose stringent requirements on sensor sensitivity, low-frequency performance and anti-interference capability.

The high-sensitivity IEPE piezoelectric accelerometer from Yangzhou Xiyuan features a built-in IEPE preamplifier. Boasting high sensitivity, excellent low-frequency response and low self-noise, it is specially developed for low-frequency, low-vibration measurement scenarios. It delivers accurate and reliable raw data for testing and monitoring of large-scale infrastructure.

Product Features

▶ Ultra-high sensitivity for capturing micro-vibration signals Sensitivity reaches up to 50 V/g, optimized for faint vibrations. Minor vibration variations can be effectively identified and acquired.

▶ Outstanding low-frequency response to extract low-frequency vibration data Overcomes the low-frequency limitations of conventional piezoelectric sensors. It can effectively acquire ultra-low-frequency signals including wind-induced sway of high-rise buildings, modal vibration of bridges and ground site pulsation, ensuring dynamic stability during testing.

▶ Isolated floating structure to reduce noise interference Its unique isolated floating design suppresses ground loop interference and significantly reduces self-noise. The transverse sensitivity ratio is ≤5%, minimizing measurement errors caused by lateral vibration to guarantee authentic and reliable data.

▶ Robust and durable for complex field operating conditions It adopts a 304 stainless steel housing and shear structure with PZT‑5 piezoelectric material for stable performance. Operating temperature: -40℃ ~ +80℃. It is suitable for outdoor, field and construction sites with drastic temperature fluctuations.

Application Scenarios

✅ Building Vibration Monitoring | Wind-induced vibration of high-rise buildings, structural pulsation tests

✅ Earthquake-related tests

✅ Vibration safety monitoring of dam bodies

✅ Bridge structural tests & structural health monitoring

✅ Ground and foundation vibration, site pulsation monitoring

✅ Geological structure research, geophysical vibration scientific experiments

Whether for long-term on-site engineering monitoring or laboratory scientific tests, the sensor accurately picks up faint low-frequency vibrations that are easily overlooked. It helps engineers and researchers obtain the real vibration status of structures, and provides solid data support for infrastructure safety assessment and geological research.
