Graphtec Data Loggers

GL100 Petit Logger

GL100-N Petit Logger

The Graphtec Petit Logger GL100-N is a highly versatile, ultra-compact data logging instrument designed for adaptable field diagnostics and laboratory testing. The core innovation of the GL100 series lies in its modular input architecture: rather than buying dedicated hardware for every distinct variable, users can instantly change the logger’s functionality by swapping out rugged plug-and-play sensor heads. The GL100-N variant is the streamlined, micro-USB driven foundation unit of the PetitLOGGER range, prioritizing massive battery life, secure wired physical connectivity, and a bright back-lit LCD for instant on-site telemetry validation.

Core Features & Technical Breakdown

  • True Modular Sensor Swapping: Features a heavy-duty, proprietary top port that accepts specialised Graphtec sensor compartments. Operators can swap between thermistors, high-accuracy temperature/humidity grids, dual-channel acceleration/vibration heads, illuminance/UV pods, and AC current clamp adapters in less than 5 seconds.
  • Dual-Layer Data Storage: Equipped with 4.9 megabytes of non-volatile onboard flash memory, supporting up to 4.9 million data points. For deep, multi-month testing windows, it includes a built-in micro-SD expansion slot supporting cards up to 32 gigabytes.
  • High-Visibility LCD Interface: A built-in, back-lit monochrome graphical screen displays live alphanumeric readouts, scrolling real-time wave trends, memory thresholds, and dual-alarm status icons without requiring a PC link.
  • Wired USB System Logic: The “N” designation highlights the high-security USB interface configuration. By omitting wireless radio hardware, the GL100-N provides an exceptionally stable, noise-free connection to PC host systems via a standard micro-USB port while vastly extending field battery lifespan.
  • Comprehensive Alarm Relay Outputs: Features a dedicated external terminal connector for digital output channels. If a modular threshold is broken (e.g., a temperature spike or vibration shock), the GL100-N can immediately fire a hardwired trigger to external warning lights, sirens, or PLC input gates.

Core Technical Specifications

  • Sampling Interval Rates: User-configurable from a high-speed 0.5 seconds up to every 30 seconds, or 1 minute up to 1 hour.
  • PC Interface: USB 2.0 via micro-USB terminal.
  • Dimensions & Weight: Ultra-compact at 66 mm X 100 mm X 27 mm; weighing approximately 90g (excluding sensor modules).
  • Power Configuration: Runs continuously via micro-USB bus power, or via 2 x AA alkaline batteries for long-term standalone remote logging.

Applications

Placed within multi-drop shipping containers, combining temperature, humidity, and acceleration heads to track cargo conditions and physical transit impacts simultaneously.
Deployed by facility technicians to swap between ambient temperature probes and clip-on AC current clamps to evaluate real-time power draw versus environmental heating output.
Tucked discreetly into display cases or clean benches to monitor delicate asset stability using integrated UV light, illuminance, and micro-climate sensor modules.
Clamped onto manufacturing equipment, motors, or conveyor frames using the acceleration head to profile mechanical wear patterns during factory uptime.

Frequently Asked Questions

â–¶ Q: Does the GL100-N require a wireless network to operate or configure?
A: No. The GL100-N is the dedicated non-wireless version of the Petit Logger. It is configured, controlled, and downloaded entirely via its physical micro-USB port using a PC running the free APS (Application Software) package, or via the on-board front buttons.
â–¶ Q: Can I connect multiple sensor heads to a single GL100-N base simultaneously?
A: The base logger contains one primary top port. However, Graphtec offers dual-module expansion adapters (such as the GS-DPA) that allow you to combine specific compatible heads. Like linking a Temperature/Humidity sensor and an Illuminance/UV sensor into the same single logger array.
â–¶ Q: What happens if the internal AA batteries run out while the unit is logging data?
A: The GL100-N utilises highly stable, non-volatile internal flash memory and a dedicated micro-SD slot. If power is lost completely, your pre-recorded data samples remain safely written to the memory hardware and will not be corrupted or wiped.
â–¶ Q: Is the configuration software free, or is there a subscription fee?
A: Every unit includes access to Graphtec’s APS platform for Windows completely license-free. The software supports automated data export to CSV formats, real-time wave graph rendering, and can manage up to 10 units simultaneously when plugged into a PC terminal hub.
