Overview
The DaqPRO 5300 is a rugged, field-deployable 8-channel standalone data logger engineered for high-fidelity analog and digital signal acquisition in industrial, environmental, and laboratory monitoring applications. Unlike PC-dependent data loggers, the DaqPRO 5300 integrates embedded signal conditioning, real-time display, non-volatile memory, and on-device configuration—enabling fully autonomous operation without external computing infrastructure. Its architecture implements precision low-noise analog front-end circuitry with 16-bit A/D conversion, internal linearization, and cold-junction compensation (for thermocouple inputs), ensuring traceable measurement integrity across diverse sensor types. Designed for long-duration unattended deployment—including outdoor installations—the system supports extended battery life (up to 40 hours), solar charging compatibility, and IP67-rated enclosures for dust- and water-immersion resistance. The device complies with CE and FCC electromagnetic compatibility standards, making it suitable for use in regulated environments where electrical safety and radiated emissions are controlled per EU Directive 2014/30/EU and FCC Part 15 Subpart B.
Key Features
- Standalone operation with integrated graphical LCD (64×128 pixels) for real-time numeric, tabular, and time-series waveform visualization
- Eight configurable analog input channels supporting universal sensor interfaces: current (0–24 mA), voltage (0–10 V, 0–50 mV), resistance (NTC, PT-100), and thermoelectric (J/K/T thermocouples)
- High-speed single-channel sampling at up to 4,000 samples per second, with programmable sample intervals ranging from once per hour to kHz-range capture
- 512 KB of onboard RAM enabling storage of up to 100 independent logging sessions with timestamped metadata
- On-device keyboard interface for full parameter configuration—including engineering unit scaling (e.g., bar, ppm, °C), alarm thresholds, and session naming
- Integrated real-time clock and calendar for ISO 8601-compliant timestamping; supports manual annotation via on-screen text editor
- USB 1.1 interface for rapid data offload and bidirectional host communication; compatible with Windows-based DaqLab software
- Internal rechargeable 7.2 V NiMH battery with smart charging circuitry and external 9–12 V DC input option
- Optional IP67-rated weatherproof enclosure and solar panel adapter for permanent outdoor deployment
Sample Compatibility & Compliance
The DaqPRO 5300 accommodates a broad spectrum of industrial and scientific sensors without requiring external signal conditioners. Analog inputs support standard 2-wire and 3-wire RTD configurations (up to eight 2-wire or four 3-wire PT-100 channels), NTC thermistors (10 kΩ / 100 kΩ), and thermocouples with automatic cold-junction compensation (±0.3 °C error). Pulse and frequency inputs (Channel 1 only) accept opto-isolated signals (0–5 V, 20–4,000 Hz), while current-loop inputs include built-in 21 Ω loop resistance for 4–20 mA transmitters. All analog channels feature ≤30 μVrms noise floor, <±0.08% FSR integral linearity, and calibrated accuracy of ±0.5% of full scale across specified ranges. The system meets CE marking requirements for EMC and safety (EN 61326-1:2013) and FCC Class B emission limits. While not certified to IEC 61000-4-x immunity levels or ATEX/IECEx zones, its robust construction and isolation design align with general-purpose industrial measurement practices under ISO/IEC 17025-accredited calibration workflows.
Software & Data Management
DaqLab is a Windows-native desktop application that serves as the central hub for post-acquisition analysis, device configuration, and compliance documentation. It enables lossless binary-to-CSV/Excel export with full metadata retention (timestamps, channel labels, engineering units, alarm flags). Users may define up to 20 custom sensor transfer functions—including polynomial calibration curves—and apply them during data download or in real time. The software provides statistical summaries (min/max/mean/stdev), overlaid multi-channel plotting, dynamic zoom/pan, and user-defined alarm zone highlighting directly on graphs. DaqLab supports audit-trail generation for configuration changes and calibration events, satisfying basic GLP/GMP documentation needs. Although not validated for FDA 21 CFR Part 11 compliance out-of-the-box, its logging architecture permits integration into validated environments when deployed with controlled change management procedures and electronic signature protocols.
Applications
The DaqPRO 5300 is routinely deployed in applications demanding reliable, portable, and self-contained data acquisition—particularly where network connectivity or continuous PC presence is impractical. Typical use cases include HVAC performance validation across multi-zone buildings; long-term thermal profiling of chemical reactors and sterilization cycles; environmental monitoring of air/water quality parameters (e.g., dissolved oxygen, pH, conductivity via analog transmitters); validation of pressure and flow instrumentation in pilot-scale process lines; and field testing of renewable energy subsystems (e.g., solar irradiance, battery bank voltage/current, wind turbine RPM). Its ability to scale raw ADC values into physical units and embed contextual annotations makes it especially valuable for ISO 9001 internal audits, equipment qualification (IQ/OQ), and technical reporting under ASTM E2500 or ICH Q9 frameworks.
FAQ
Can the DaqPRO 5300 operate continuously for more than 24 hours?
Yes—on a fully charged 7.2 V NiMH battery, typical runtime ranges from 25 to 40 hours depending on sampling rate, display backlight usage, and active channel count.
Is external power required for continuous operation?
No—the device operates autonomously on battery power. However, an external 9–12 V DC supply or optional solar charger can sustain indefinite operation in remote deployments.
Does the system support alarm-triggered data logging?
While it does not support conditional (event-driven) sampling, users can configure visual and audible alarms on-screen and manually initiate new logging sessions upon threshold breaches.
Can I calibrate individual channels using DaqLab?
Yes—DaqLab allows multi-point calibration of any analog input using user-supplied reference values, generating correction polynomials applied during data retrieval.
What is the maximum cable length supported for PT-100 sensors?
For 2-wire configurations, total lead resistance should remain below 5 Ω to maintain ±0.5 °C accuracy; 3-wire connections mitigate lead resistance errors and support longer runs with appropriate shielded twisted-pair cabling.
