Overview

The CR6 High-Capacity Data Acquisition System (High-Cap DAQ), designed on decades of infrastructure and environmental monitoring experience, is used by some of the largest monitoring networks worldwide. With the unique ability to serve both as an edge device and gateway, this simplifies networks that would otherwise require discrete devices to provide complete access to your data.

This unique system is used where reliability, flexibility, and compatibility are essential to your success. The CR6 ecosystem supports an array of powerful peripherals that add channel capacity, distributed measurements, and communications capabilities, as well as measure vibrating wire sensors dynamically.

Campbell Scientific’s vibrating wire measurement devices, including the CR6, are the only devices that use patented VSPECT™ technology. VSPECT filters external noise from your sensor and gives you diagnostic information about the quality of your vibrating wire measurement.

Learn about our patented VSPECT at our VSPECT Essentials web resource.

The dynamic vibrating wire measurement technique is protected under U.S. Patent No. 8,671,758, and the vibrating wire spectral-analysis technology (VSPECT) is protected under U.S. Patent No. 7,779,690.

Key Advantages

Rugged, Wireless Edge Device and Gateway with Universal Channels and VSPECT™ Technology
Designed for critical, expanding applications in geotechnical, structural health, and environmental data monitoring projects

Technical Description

The CR6 is the only High-Capacity Data Acquisition System currently available that operates as an edge device and gateway with connectivity, provides an industry standard for rugged design, has universal sensor compatibility and communications options, and includes VSPECT for vibrating wire measurements.

Edge and Gateway Device

The variability and site-specific challenges and constraints that exist in robust monitoring networks typically result in a wide array of devices to achieve full functionality. With built-in and modular measurement, processing, control, and communications capabilities, the CR6 is the only device that is needed.

As a gateway device, the CR6 converts the data measured into the format or protocol required to seamlessly communicate on your network—whether on your computer or the cloud. Entry into the network does not require a separate edge device, as the CR6 also fills this role. Additionally, the CR6 forms a network as a connectivity device via spread-spectrum radio, Wi-Fi, serial, and RS-485.

Using the CR6 as an edge device and gateway with connectivity allows you to standardize on a single platform in your monitoring program. This simplifies purchasing, inventory management, and an overall required knowledge base. The CR6 is capable of a wide range of more than thirty-five M2M protocols that include PakBus, MQTT, DNP3, IPv4, IPv6, HTTP/HTTPS, and PPP. Connectivity options include cellular, radio, satellite, Ethernet, and Wi-Fi. These communications methods enable access to critical data and the ability to receive alarms triggered by user-configured thresholds and events.

Native Vibrating Wire Using VSPECT

VSPECT, Campbell Scientific’s patented technology for measuring vibrating wire sensors, significantly improves vibrating wire sensor measurements—regardless of the manufacturer of the sensor. For more details about this unique technology, visit our VSPECT Essentials web resource.

Integrated Benefits for Simplicity and Reduced Costs

The integrated benefits and capabilities of the CR6 make it the most flexible data acquisition system available. In addition to several spread-spectrum radio options that are compatible with available frequencies across the world, it also includes Wi-Fi, Ethernet, and compatibility with modular cellular and satellite modems. Using Campbell Scientific communications peripherals ensures complete compatibility and extremely low power consumption.

The built-in charge regulator, with direct connections for main power or solar panels, is used to keep your battery charged. An intelligently designed and maintained power supply ensures long-term functionality and helps to capture data from critical events when you need it.

With regular data collection intervals or remote access, the 4 MB of onboard CR6 memory will likely be sufficient. However, if your application requires high measurement frequency; long, unattended deployments; or data storage redundancy, the CR6 has built-in expandable memory via a microSD card.

Communications Options

The CR6 High-Capacity Data Acquisition System is available in different integrated communications frequency radio options.

CR6-WIFI

The CR6-WIFI comes factory-configured as a Wi-Fi access point. Alternatively, the CR6-WIFI can be configured to join an existing Wi-Fi network with standard or Enterprise (EAP) security.

CR6-RF407

This 900 MHz, 250 mW, frequency-hopping spread-spectrum radio option can join a high-speed “mesh topology” radio network of other CR6s, which is ideal for medium-range, license-free radio communications.

CR6-RF412

Designed primarily for unlicensed operation in Australia and New Zealand, this 922 GHz, 250 mW, frequency-hopping spread-spectrum radio can join a high-speed “mesh topology” radio network of other CR6s and is also ideal for medium-range, license-free radio communications.

CR6-RF422

Used in the UK and EU and ideal for short- to medium-range, license-free radio communications, this 868 MHz, 25 mW option includes listen-before-talk (LBT) and adaptive-frequency-agility (AFA). It can join a high-speed “mesh topology” radio network of other CR6s using the included RF422 radio.

CR6-RF452

With this internal 900 MHz, 1 W, frequency-hopping spread-spectrum radio option, the CR6-RF452 can be part of a “star topology” network where all radio-frequency (RF) traffic routes back through the gateway. This option is ideal for long-range, license-free radio communications.

Universal Measurement and Control Terminals

The Universal or “U” terminals allow each terminal to be configured to measure a multitude of different types of sensor outputs. This allows the CR6 to be used in many different applications, regardless of the sensor types required—analog, digital, smart, or vibrating wire. This nearly limitless array of sensors includes inclinometers, meteorologic, hydrologic, piezometers, water quality, etc. The flexibility of Universal channels allows you to standardize on a single monitoring platform for all projects.

Support Staff

Recognized for more than 50 years for our outstanding customer support, Campbell Scientific includes experienced product engineering teams, knowledgeable technical support, attentive sales staff, and market-focused professionals who are committed to ensuring your success throughout the lifetime of your project.

Rugged Design

Unique to all CR6 High-Capacity Data Acquisition Systems is the design and manufacturing process used to ensure operational integrity in the most extreme environments. Each CR6:

Includes surge electrostatic discharge (ESD) and overvoltage protection, as well as dust protection.
Is fully tested for shock and vibration tolerance.
Is factory chamber tested for its full operational temperature range (standard range -40° to +70°C and extended range -55° to +85°C).
Has been proven in hundreds of real-world applications.

These extreme measures are required to manufacture a product with a meantime between failure (MTBF) of 557 years! This means that if you purchase a CR6 today, your probability of failures during the warranty period (three years) is 0.6%. The CR6 High-Capacity Data Acquisition System will last the entirety of your project, even if that means decades.

Enclosures

The CR6 and its power supply can be housed in any of our standard enclosures.

Power

The CR6 uses an external power source and has a built-in charger/regulator. Intelligent power sourcing autoselects the highest voltage from three input sources (CHG, BAT, or USB) to operate in one of the following four modes:

UPS (recommended)—A 16 to 32 Vdc source, solar panel (SP10, SP20), or power converter is used to charge a 12 Vdc battery, such as our BP7, BP12, or BP24.
12 Vdc battery or other reliable 12 Vdc source
Charge only—dc power supply (16 to 32 Vdc)
USB—Powered over 5 Vdc USB port for setup, programming, and testing (will not charge battery or boost USB power to provide 12 Vdc to the SW12 switched battery terminals or the 12V power output terminal)

Software

CRBasic, the CR6's full programming language, supports simple or complex programming and many on-board data reduction processes. The CR6 is compatible with CRBasic (version 3.5 or higher).
