DaqExpert is a general-purpose data acquisition platform built on National Instruments hardware. Read accelerometers, proximity probes, velocimeters, RTDs, thermocouples, pressure and position sensors — virtually any NI-compatible signal — then go further with specialized modules for vibration analysis, rotating-machine balancing, power-quality analysis and machine commissioning.
Diagnosing machines requires correlating many signal types — vibration, temperature, pressure, electrical. But available tools are either single-purpose or enterprise-grade and out of reach.
Vibration-only analyzers, standalone power meters, isolated temperature loggers — none of them share a common timeline. Correlating a bearing fault with a thermal event or a power disturbance requires manual effort across separate systems.
A certified CAT III vibration analyst costs $150–$250/hour. Setting up an NI acquisition system from scratch requires expertise most teams don't have. Enterprise platforms require 6+ months of deployment and in-house specialists.
Enterprise licenses start at $50,000/year. Cloud SaaS solutions force proprietary sensors. Your production data ends up on servers you don't control — and none of these tools support balancing, commissioning or power quality in one package.
DaqExpert gives you a universal acquisition core on NI-DAQmx hardware, plus four specialized analysis modules — vibration, balancing, power quality, commissioning — all sharing the same timeline and the same report engine.
Plug in your NI hardware, configure channels in a few clicks. Works with tasks you already set up in NI MAX. No 6-month integration project.
Clear, actionable diagnostics. AI models translate sensor anomalies into plain-language recommendations any technician can act on immediately.
On-premise deployment available. No production data is ever sent to third-party servers without your explicit consent.
Alarm zones A, B, C, D by machine class. Normative vibration compliance from the first acquisition — no expert configuration required.
Compatible with the full National Instruments lineup. USB-6xxx, cDAQ, PXI. If you already configured a task in NI MAX, DaqExpert picks it up automatically.
Built on top of the universal acquisition core, each module extends DaqExpert into a full analysis environment for its domain.
Real-time FFT, acceleration→velocity→displacement integration, XY orbits, Campbell diagram, envelope analysis, spectrograms, order tracking, ISO 10816/20816 compliance zones, AI anomaly detectors per machine type.
Field balancing using the influence-coefficient method — single-plane and two-plane. Magnetic-pull correction and no-trial-weight estimation (velocity / FEA based). Guided workflow from initial run to correction weights, with results exported directly into the report.
Three-phase P/Q/S, power factor, harmonic content (1X→11X), phase imbalance and phasor diagram. Integrates external power meters over Modbus TCP and correlates electrical measurements with mechanical signals on the same timeline.
Purpose-built for commissioning rotating machines: load-rejection and overspeed testing, heat runs and thermal conformity, open-circuit / TIF measurements, and one-click generation of professional commissioning reports. Designed around the real workflow of field engineers.
