An accelerometer sensor converts vibration into an electrical signal.
The output type determines how this signal is transmitted and how well it resists noise or signal loss.
Micromega Dynamics’ Recovib® MEMS accelerometers support the main industrial formats — 4–20 mA current loop, voltage, differential voltage — ensuring accurate, stable data from DC to several kilohertz.
Analog Output
An analog accelerometer delivers a continuous signal proportional to acceleration.
It’s the most common and versatile format, compatible with most acquisition systems and offering real-time response across a wide frequency range.
Micromega provides analog outputs in voltage, differential voltage, and 4–20 mA current loop, allowing engineers to adapt to distance, noise environment, or PLC integration needs.
This flexibility makes Recovib® sensors suitable for civil engineering, machine monitoring, and wind turbine applications.
Current Output (4–20 mA)
The 4–20 mA current loop is ideal for industrial environments requiring long cable runs or high noise immunity.
The signal remains stable over distances exceeding 150 m and connects directly to standard monitoring systems.
Micromega integrates this output on Recovib® sensors to simplify field deployment and reduce interference issues.
Voltage Output
A voltage output accelerometer (e.g., 0–5 V or ±10 V) is simple to use and easy to interface with laboratory or local monitoring setups.
Also integrated in micromega’s accelerometers, it offers high resolution and fast response for short to medium cable lengths, making it a preferred choice for test benches and on-site measurements.
Differential Voltage Output
A differential voltage accelerometer sends two complementary signals — one positive, one inverted — and measures their difference.
This cancels electromagnetic noise, ensuring high accuracy even with long cables.
It’s ideal for low-noise or high-resolution applications, such as semiconductor manufacturing or structural health monitoring.
Micromega’s IAC-HiRes and IAC-UHRS models can be parametered with this output for exceptional stability and precision.
Digital Output
A digital output accelerometer converts analog data into digital form (SPI, I²C, RS-485) before transmission.
It offers strong noise immunity and seamless integration with embedded systems, but is less suited for long distances.
Analog outputs (voltage or current) remain the standard for rugged industrial monitoring.
Choosing the Right Output
| Application | Recommended Output |
| Long cable runs, harsh sites | 4–20 mA current loop |
| Standard vibration monitoring | Voltage output |
| High precision, low noise | Differential voltage |
| Embedded or smart systems | Digital output |
Micromega Dynamics designs each Recovib® Industrial Accelerometer to provide reliable, noise-free signals in all these configurations — ensuring robust data transmission across demanding industrial environments.
