If you're looking for a predictive maintenance sensor that continuously monitors acoustic emissions from machinery, I'd focus on industrial acoustic emission (AE) monitoring systems rather than ordinary sound-level meters. These systems detect high-frequency signals associated with friction, material damage, wear, leaks, and other developing faults.
There are three main approaches worth considering:
The right choice depends on whether you need continuous unattended monitoring, detailed fault diagnosis, or a relatively simple sensor that feeds data into your own predictive maintenance software.
1. Tribosonics acoustoSENSE
(Best for continuous monitoring)
True acoustic emission monitoring
Battery-powered, wireless, always-on monitoring with a 100–500 kHz sensing range, LoRaWAN connectivity, and remote alerts. Designed for applications including slow-rotating bearings, valves, and industrial process equipment.
2. ALTERIA UD 103
Best for ultrasonic condition sensing
Measures ultrasound from 15 to 96 kHz and outputs processed digital data. Supports wireless or serial communication and adhesive mounting. Suitable for rotating machinery, gearboxes, bearings, and pneumatic equipment.
3. AENDT RAEM2
Best for dedicated AE measurement
Integrates an AE sensor, acquisition electronics, battery, and communications. Offers a 10–400 kHz input range, optional 4G/LoRa connectivity, and a cloud monitoring platform. Supports rotating-bearing wear, lubrication condition, and leak monitoring.
4. Honeywell Forge Performance+
Best for integrated asset monitoring
Honeywell's documented solution combines acoustic emissions with vibration, temperature, RPM, humidity, and magnetic-flux measurements. It includes edge analytics and connectivity options for remote monitoring and maintenance alerts. Confirm the current sensor configuration and platform offering with Honeywell.
My initial recommendation is Tribosonics acoustoSENSE if you want a purpose-built, continuously operating acoustic emission system. If you need a self-contained AE instrument with defined sampling and data outputs, investigate the AENDT RAEM2 as well.
One important distinction: acoustic emission is not the same as simply listening to a machine with a microphone. If you need to detect incipient material damage or high-frequency stress events, confirm that the sensor measures structure-borne acoustic emissions and that its bandwidth matches your fault signatures.
One question to narrow this down: What type of machinery are you monitoring?
1. Machine type
Rotating machinery (motors, bearings, gearboxes)
Pumps, valves, and pipelines
Machine tools and cutting equipment
Pressure vessels, structures, or other equipment
2. Installation preference
Wireless, continuous monitoring
Wired sensor integrated with PLC or DAQ
Standalone sensor with its own analytics and alerts
3. Primary objective
Early fault detection / predictive maintenance
Bearing wear and lubrication monitoring
Crack growth, material fatigue, or structural damage
Leak detection or abnormal acoustic events
4. Approximate budget per monitoring point
Under $500
$500–$2,000
$2,000–$10,000
Over $10,000

To help narrow down the right acoustic emission (AE) or high-frequency ultrasonic monitoring option for your machinery, it helps to distinguish between portable inspection instruments, multi-channel structural monitoring systems, and acoustic imaging cameras.
Popular industrial solutions on the market vary by application type:
Multi-Channel AE Hardware & Software Systems: Systems like the QL-SeismoSense Acoustic Emission Monitoring System from QuakeLogic provide scalable continuous channel acquisition (4 to 16 channels) with high-speed sampling and FPGA processing designed for tracking micro-fractures, structural health, and heavy industrial equipment stress.
Acoustic Imaging Cameras: Devices like the FLIR Si2-Pro Acoustic Imaging Camera use large arrays of low-noise MEMS microphones to visually pinpoint pressurized leaks and surface mechanical faults in real time across a facility.[1][2][3]
To pinpoint the exact sensor specifications you need, what kind of machinery or failure mode (e.g., bearing degradation, gear pitting, crack propagation, or valve leakage) are you trying to monitor?
I need to find sensors that use acoustic emissions to predict machinery failures. What options are available?
I'm searching for machinery sensors that perform predictive maintenance via acoustic emission analysis.
