Overview
Multiparameter datalogger NOVALog 3.0 for in-situ testing, load tests and monitoring, up to 24 channels.

Product description
NOVALog 3.0 is a compact, user-configurable data acquisition unit designed for field and laboratory use. The hardware platform has been updated to reduce weight and increase configurability while preserving support for common analog sensors. The unit is compatible with field work and construction-site conditions.

Supported sensors

• Vibrating-wire sensors
• Load cells
• Displacement transducers
• Inclinometers
• Environmental sensors (temperature, humidity, pressure)
• Groundwater level probes

Performance and channels
The system integrates a high-performance 24-bit A/D converter with synchronous sampling up to 200 Hz. Input capacity is 24 channels provided by three 8-channel ADC modules, enabling synchronous acquisition across all channels for dynamic and static tests.

Mobility and battery

• Internal rechargeable lithium battery replacing previous lead-acid pack
• Significant weight reduction for field portability
• Extended operating autonomy >8 h (typical, depending on configuration)
• Intelligent battery status management and stable power delivery on site

Power and noise suppression
The unit includes an integrated DC filter to suppress mains-originated disturbances from 220 V supplies, reducing electrical noise and protecting signal integrity in environments with unstable power.

Maintenance and modularity

• User-replaceable components and simplified onsite maintenance
• 5×20 mm cartridge fuse, replaceable by the user
• Modular board with 4-pin circular sensor connectors and dip-switch channel configuration
• Optional more robust monitor for high-vibration environments
• Mechanical improvements for increased durability

Interface and data handling
12” resistive touch display provides local configuration, real-time graphs and data management without a PC. Standard configurations are preloaded; data are stored in internal memory and exported via USB for offloading and analysis.

New functionalities

• Manual acquisition control
• Programmable acquisition steps, including asynchronous modes
• Notes insertion during tests linked to specific measurement points
• Ability to reopen data sessions directly on the unit
• Real-time computed formulas
• Optional real-time recording and viewing on an external PC (UART/serial)

Applications

• Load tests on slabs, beams, piles, anchors, plates and bridges
• Flat jack testing
• Pumping tests and hydrogeological investigations
• Multiparameter measurements in construction sites and laboratories
• Environmental and geotechnical monitoring

Key features

• Compatible with most analog sensors on the market
• 24 input channels with synchronous sampling up to 200 Hz
• Lightweight unit with internal rechargeable lithium battery
• User-friendly touch-screen interface
• Measurements displayed in engineering units
• Automatic data storage and USB export
• Electrical noise filtering for stable power supply
• Reinforced components and simplified maintenance

Accessories
