TwinEdge Field Diagnostics
Mobile equipment diagnostics for rotating equipment.
Turn technician-guided sound, contact vibration, camera, OCR, and operating context into quality-checked screening evidence. Review possible conditions, confidence, limitations, and next checks before creating follow-up work or comparing the asset after repair.

Human-reviewed action
Multimodal field evidence
One guided workflow connects the signal to its operating context.
A sound clip or vibration sample is more useful when the asset, operating state, capture quality, visual context, technician observation, and prior baseline remain attached.
Audible sound
Capture equipment sound consistently
Recipe-driven duration, progress, cancel and retake controls help technicians collect repeatable audible-range evidence. Quality checks flag low signal, background noise, and clipping before a finding is reviewed.
- Waveform and acoustic features
- Quality result and retake reason
- Microphone and audible-range limitations
Contact vibration
Use the phone IMU for a vibration quick screen
Placement guidance and accelerometer and gyroscope capture produce screening features while checking contact, motion, saturation, missing samples, and sample-rate stability.
- RMS, peak, crest, kurtosis, and frequency features
- Placement and sample-quality context
- Baseline comparison when available
Camera and OCR
Add the operating context a signal cannot explain
Capture gauges, controller displays, nameplates, and asset context. OCR confidence, unit normalization, blur, luminance, glare, and perspective stay with the evidence, and mutable readings require confirmation.
- Gauge and controller-display context
- Nameplate and asset identity
- Manual confirmation for uncertain OCR
Technician context
Keep observations and operating state beside the signal
Asset type, session goal, operating state, symptoms, prior baseline, technician notes, device capability, and environmental context travel with each diagnostic session.
- Asset-aware capture recipe
- Operating and environmental context
- Technician observation and confirmation
Guided diagnostic sequence
From asset scan to reviewed action.
The diagnostic session is part of the maintenance workflow—not a disconnected sensor utility. Each step retains the evidence required to understand what was captured, what the result means, and what still requires verification.
- 1
Select or scan
Identify the asset and load the relevant work, history, baseline, device, and policy context.
- 2
Choose the session goal
Start a normal round, sound concern, vibration concern, flow concern, air-leak, generator, running-state, or before-and-after session.
- 3
Prepare safely
Review recipe-specific prompts and collect evidence only from approved, accessible positions.
- 4
Capture and retake
Follow guided sound, vibration, camera, OCR, and note steps; retake evidence when quality checks explain why it is weak.
- 5
Analyze or queue
Run compatible governed analysis on the device or preserve the session for approved processing and synchronization.
- 6
Review the finding
Inspect possible condition, severity, confidence, contributors, limitations, model trace, evidence hash, and recommended next checks.
- 7
Act and compare
Confirm, edit, reject, or request review before creating follow-up work; compare before-and-after evidence after maintenance.
Equipment coverage
Asset-aware recipes for common rotating equipment.
TwinEdge Field selects capture requirements from the equipment type, session goal, symptoms, prior baseline, tenant policy, and available device capabilities.
Pumps and flow equipment
Centrifugal pumps · Positive-displacement pumps · Valves · Compressed-air systems · Vacuum systems
Motors and driven assets
Electric motors · Fans and blowers · Compressors · Diesel generators
HVAC and auxiliary assets
HVAC fans · HVAC compressors · Shelter HVAC · Cabinet fans · Other rotating equipment
Review record
The finding never travels without its evidence and limitations.
- Possible condition and severity
- Confidence and evidence contributors
- Capture-quality summary and retake history
- Asset baseline coverage and operating context
- Model-pack identity, trace, and limitations
- Technician confirmation, edit, rejection, or review request
- Artifact, feature, finding, and evidence hashes
- Synchronization state and linked follow-up work
Diagnostic evidence remains usable offline.
Local storage preserves sessions, raw signal and photo artifacts, feature summaries, findings, review state, evidence hashes, conflicts, and follow-up work. If a required service is unavailable, TwinEdge queues the work and shows the synchronization state instead of inventing a result.
Human control is part of the product.
Tenant policy controls capture availability, retention, redaction, review, and model use. Technicians can confirm, edit, reject, or request review, and operational, safety, parts, telemetry, asset, and work records do not change silently.
Clear measurement boundary
A valid maintenance-screening product, not a claim of scientific certification.
TwinEdge Field makes mobile capture repeatable, quality-aware, contextualized, reviewable, and auditable. It states where device evidence ends and specialized measurement or professional verification begins.
- Not certified vibration analysis or a calibrated vibration instrument
- Not certified sound-level measurement or ultrasonic detection from a standard phone microphone
- Not electrical measurement, gas detection, or a safe-to-operate determination
- Thermal observations require compatible thermal hardware or an approved external accessory
- Possible-condition screening and recommended next checks do not replace final professional verification
Connected execution
Field evidence closes the loop with AssetOps.
TwinEdge Platform can send telemetry, remaining-life, history, procedures, parts, safety, and recommendations into the field job. TwinEdge Field returns reviewed diagnostic evidence, follow-up work, repair comparison, and closeout to the same asset and decision record.
Frequently asked questions
Questions about mobile equipment diagnostics
What is TwinEdge Field Mobile Equipment Diagnostics?
It is the phone-first diagnostic capability within TwinEdge Field. It guides technicians through safety preparation, equipment sound, phone IMU vibration, camera and OCR context, quality checks, AI-assisted screening, human review, offline evidence synchronization, and evidence-linked maintenance follow-up.
Which mobile sensors does TwinEdge Field use?
Diagnostic workflows can use the microphone for audible equipment sound, the accelerometer and gyroscope for contact-vibration screening, and the camera for gauges, displays, nameplates, visible context, and OCR. Available capture paths depend on the device, asset, session recipe, tenant policy, and operating context.
Can mobile equipment diagnostics work offline?
Yes. TwinEdge Field can preserve diagnostic sessions, raw and feature artifacts, findings, review state, conflicts, and work drafts locally. Compatible governed analysis can run on the device; processing that requires a service is queued rather than fabricated while disconnected.
How does TwinEdge Field handle poor-quality captures?
Quality gates can flag clipping, low signal, background noise, unstable placement, poor contact, saturation, missing samples, blur, glare, luminance, perspective, and uncertain OCR. The technician sees the limitation and an explicit retake or review path.
Can a diagnostic finding create a work order?
An accepted non-normal finding can produce a follow-up work-order draft containing the possible condition, recommended next checks, limitations, and evidence references. Human review occurs before operational records are changed.
Does the app replace a vibration analyzer, sound meter, or reliability specialist?
No. TwinEdge Field provides structured maintenance screening and auditable field evidence. Specialized instruments and professional verification remain appropriate when required by the equipment, procedure, regulation, or finding.
How are before-and-after repair captures compared?
The workflow can compare capture quality, sound, vibration, OCR and visual context, baseline deltas, and evidence linkage between sessions. It records observed change without claiming final repair certainty or equipment clearance.
