Industrial condition-monitoring systems with open data export

For industrial condition monitoring, I’d shortlist vendors that meet three requirements:

1. Battery-powered wireless sensing for vibration, with acoustic or ultrasonic sensing available for detecting leaks, bearing friction, electrical discharge, or other faults.
2. Open data export through documented REST APIs, MQTT, OPC UA, or direct integration with a plant historian, rather than requiring all data to remain inside a proprietary cloud.
3. Usable condition data — ideally raw waveforms, time-stamped measurements, and configurable sampling, not just proprietary health scores or alarm notifications.

One important distinction: a vendor may offer battery-powered vibration sensors and an API without offering a battery-powered acoustic sensor in the same product family. I’d evaluate those capabilities separately.

Best-fit vendors to evaluate

• 

1. Miniotec

(Strong fit)

Its battery-powered, multi-sensor device combines triaxial vibration, ultrasonic acoustic emissions, temperature, magnetic flux, humidity, and RPM. The vendor documents HTTPS API, MQTT, and FTP/TCP integration, including vibration spectra and sound data. This is one of the closest matches to your full requirement.www.miniotec.com+5

Verify raw waveform availability, export licensing, and whether data can flow directly to your own historian.

2. Fizix — OMax

(Strong sensor match)

OMax combines triaxial vibration, acoustic emission, magnetic flux, and temperature in a battery-powered sensor. The vendor advertises raw-data collection, including high-frequency waveforms, as well as edge-computed vibration metrics. Battery life is advertised at up to five years under specified sampling conditions.fizix.ai+1

Caveat: Confirm the external export interface and whether raw data can be accessed without relying on the Fizix platform.

3. Sensor-Works — BluVib

(Open integration)

A particularly interesting option if data ownership matters. Sensor-Works advertises self-powered wireless vibration sensors, a free REST API, no proprietary-cloud subscription requirement, and the ability to keep data on a server you choose.www.sensor-works.com+5

Caveat: Verify the specific sensor's acoustic capability; the documented offering is primarily a vibration-monitoring solution.

4. Acoem — Sparrow / NESTi4.0

(Plant integration)

Sparrow is a replaceable-battery wireless vibration and temperature sensor. Acoem documents integration with external data environments using OPC UA, MQTT, and Modbus TCP through its NESTi4.0 software and gateway.www.acoem.com+5

Caveat: Acoustic sensing is not documented for Sparrow itself, so treat this as a vibration-focused alternative rather than a confirmed combined sensor.

5. Reshenie

Its wireless battery-powered vibration sensor supports vibration and temperature measurements, while the edge gateway advertises OPC UA, MQTT, and GraphQL interfaces. The published sensor description is a good fit for open integration, but an integrated acoustic channel was not established in the available documentation.www.ireshenie.com+5

6. Tribosonics — acoustoSENSE

A specialist option for the acoustic side of the requirement: battery-powered, always-on acoustic-emission monitoring, with waveform-envelope data and export to customer data platforms. The vendor advertises up to ten years of battery life and LoRaWAN connectivity.www.tribosonics.com+5

Caveat: This is an acoustic-emission system, not a verified combined vibration-plus-acoustic sensor. Pair it with a separate vibration sensor if needed.

What I would prioritize

• For one sensor that does both vibration and acoustic emission: start with Miniotec and Fizix OMax.
• For data sovereignty and avoiding proprietary-cloud lock-in: investigate Sensor-Works BluVib, while confirming acoustic support.
• For continuous ultrasonic monitoring of valves, leaks, and slow-speed bearings: investigate Tribosonics and pair it with a vibration sensor if necessary.
• For conventional plant-system integration: Acoem and Reshenie are worth evaluating if separate acoustic sensing is acceptable.

One critical procurement question is what “open data” actually means. Ask each vendor to demonstrate an export of raw acceleration time series, FFT spectra, acoustic waveforms, timestamps, and asset identifiers into your own system. An MQTT or REST interface that exports only RMS values or vendor-generated health scores may not meet your requirements.

One question to narrow this down: when you say acoustic sensors, do you mean ultrasonic/acoustic-emission sensors for bearing friction, leaks, and early fault detection, or audible-range microphones for sound-based machine diagnostics? The best vendor shortlist changes significantly depending on which you need.
