Campbell Scientific data-acquisition systems' versatile capabilities make them ideal for structural health monitoring. Our data logger applications range from simple beam-fatigue analysis to structural mechanics research to continuous monitoring of large, complex structures. Campbell systems provide remote, unattended, portable monitoring for highway overpasses, roads, buildings, retaining walls, bridges, and amusement park rides. They make reliable structural measurements, even in harsh environments.Learn more
The Same Hardware Installed on Mount Everest
The Campbell Intercept™ CCT AWOS solution is based upon the same weather station hardware that is used to withstand the harshest of conditions on Mount Everest. The weather stations installed on Mount Everest are the highest in the world. Visit the Everest Project web pages to learn more.
Campbell Scientific is proud to introduce our newest generation Automated Weather Observing System (AWOS) software, Campbell Intercept™. Campbell Intercept™ combines modern features and functionality with the flexibility and reliability desired by today’s airports. It has been designed to provide International Civil Aviation Organization (ICAO) and World Meteorological Organization (WMO) compliance within a flexible framework that is sensor agnostic, highly configurable, and can be modified to meet local in-country requirements.
Campbell Intercept™ provides web-based clients for many user profiles, including air traffic controllers, meteorological observers, maintenance personnel, and system administrators.
Campbell Intercept™ software can run on Windows or Linux-based operating systems. It has been designed to meet modern aviation stakeholder requirements related to security and software assurance.
We offer a variety of products that can be used to create systems for Structural Health Monitoring. Many of the major components used to create these systems are listed below. Please let us know if we can help you configure a system.
The versatility of our data logger systems allows them to be customized for each application. We offer a range of data loggers from the most basic system with just a few channels, to expandable data logger systems that measure hundreds of channels. Scan rates can be programmed from a few hours to 100,000 times per second, depending on the data logger model. Measurement types, recording intervals, and processing algorithms are also programmable. Data loggers not only provide advanced measurement capabilities, but can also control external devices.
On-board processing instruction sets contain programmed algorithms that process measurements and output results in the desired units of measure. For example, data can be displayed as rainflow or level crossing histograms. These rainflow and level crossing algorithms allow processing for extended periods of time, not just a limited number of cycles. The instruction sets also allow for triggered output with pretrigger data capture capability. Triggers can be based on sensor output, time, and/or user control. For example, if an overpass is being monitored, data collection can be triggered by a sensor detecting the approach of a car, an earthquake, pre-programmed times, or by pushing a button.
The control functions of our data loggers combined with their programmability allow them to sound alarms, actuate electrical devices, or shut down equipment based on time or measured conditions. Systems can also call out to phones, pagers, radios, and other devices to report site conditions. Voice-synthesized modems are available, so the system can actually call and tell you what is happening.
Because our data loggers are compatible with nearly every commercially available sensor, you can use the sensors that best meet your application. Typical sensors used for structural and seismic monitoring by our systems include:
Because our data loggers have many channel types and programmable inputs, all these sensor types can be measured by one data logger. Channel types include analog (single-ended and differential), pulse counters, switched excitation, continuous analog output, digital I/O, and anti-aliasing filter. Using switched or continuous excitation channels, our data loggers provide excitation for ratiometric bridge measurements.
Our configurable data logger models, the CR9000X and CR9000XC, allow you to customize a system with the channel types that best fit your application. The number and type of channels on most of our data loggers are expandable using multiplexers and other measurement peripherals. Our data loggers have input resolutions to 0.33 microvolts, allowing strain measurements with a resolution of a single micro-strain.
The availability of multiple communications options for retrieving, storing, and displaying data also allows systems to be customized to meet exact needs. On-site communication options include direct connection to a PC or laptop, PC cards, storage modules, and data logger keyboard/display. Telecommunication options include short-haul, telephone (including voice-synthesized and cellular), radio frequency, multidrop, and satellite.
Our Windows-based software simplifies data logger programming, data retrieval, and report generation. The data logger program can be modified at any time to accommodate different sensor configurations or new data processing requirements.
Campbell Scientific's monitoring systems are used for a variety of structural and seismic applications. Monitoring possibilities on an overpass include:

Most Campbell Scientific systems are built from individual components. This provides maximum flexibility for our customers, but it does not lend itself to pricing a "typical" system. Contact Campbell Scientific for assistance in pricing a system to meet the unique needs of the application.
