Overview

A high-capacity data acquisition system serving as both an intelligent edge device and a communications gateway. Features Universal Terminals for unmatched sensor flexibility.

The CR6 defines the new standard for high-capacity data acquisition (DAQ). Engineered based on decades of infrastructure and environmental monitoring experience, it is deployed in some of the world's most critical monitoring networks. Its unique architecture allows it to function simultaneously as a precise measurement edge device and a communications gateway, simplifying network topology by removing the need for separate peripherals. At its core, the CR6 is built for flexibility. It introduces "Universal Terminals" which allow engineers to configure any port for analog, digital, or smart sensor inputs via software. Combined with on-board spectral analysis for noise-free vibrating wire measurements and an integrated solar charge regulator, the CR6 offers a complete, standalone solution for long-term remote monitoring.

Detailed Description

The Universal Terminal Advantage

The CR6 eliminates the frustration of mismatched port types. Its 12 Universal (U) terminals utilize a patented technology that allows each specific terminal to be software-configured for any function.

  • Analog: Measure high-precision voltage or current loops.
  • Digital: Act as control ports, counters, or triggers.
  • Smart Protocols: Native communication with SDI-12, RS-232, and RS-485 sensors.
  • Vibrating Wire: Direct connection without external interfaces.

Advanced Vibrating Wire Technology

Unlike standard loggers that use simple pulse-counting, the CR6 employs advanced Spectral Analysis technology. This dynamic measurement technique analyzes the frequency spectrum of the returning signal, effectively filtering out external electrical noise.

This capability provides diagnostic information on signal quality and ensures rock-solid data even when sensors are installed on long cable runs in electrically noisy environments, such as construction sites or power plants.

Rugged Design & Reliability

Reliability is engineered into every component. The device features multi-stage surge protection, including gas discharge tubes on inputs to protect against lightning and electrostatic discharge (ESD).

Factory tested for shock, vibration, and extreme temperature cycling (-55°C to +85°C options), the CR6 boasts a calculated Mean Time Between Failure (MTBF) of over 500 years, ensuring it lasts the entirety of your project lifecycle.

Integrated Power & Comms

To reduce site clutter, the CR6 integrates a solar charge regulator directly into the chassis. You can connect a solar panel and battery directly to the unit without external hardware.

Connectivity is equally robust, with built-in Ethernet for LAN/WAN integration and expansion slots for Wi-Fi, Cellular, or Spread-Spectrum Radio modules, allowing the device to adapt to any telemetry requirement.
