Vibration sensor

High‑Precision Vibration Sensor – Industrial & Automotive Applications

This 3‑axis piezoelectric vibration sensor delivers micron‑level resolution, making it ideal for predictive maintenance, structural health monitoring, and automotive ride‑comfort systems. Its compact 10 mm diameter and 20 mm length fit seamlessly into tight instrumentation bays while maintaining a low profile for aerospace and rail applications. With a factory‑calibrated sensitivity of 1.5 mV/g and a wide bandwidth from 0.1 Hz to 10 kHz, the sensor captures both slow, large‑amplitude motions and rapid, high‑frequency shocks. The integrated MEMS circuitry converts raw vibration data into a 4–20 mA current loop, ensuring reliable communication over long cable runs in harsh industrial environments. Its robust hermetic sealing and limited temperature drift (±0.05 %/°C) provide stable operation from –40 °C to +85 °C.

Designed for real‑time monitoring, the sensor features low power consumption (35 µW at 5 V) and a programmable gain amplifier that allows on‑board signal conditioning. The unit is compatible with common industrial protocols such as Modbus‑RTU and EtherCAT, and its compact PCB layout allows rapid integration into field‑bus gateways or embedded controller housings. Whether measuring machine tool chatter, bearing fatigue, or vehicle suspension dynamics, this vibration sensor offers the accuracy, durability, and connectivity required for mission‑critical systems.
