Campbell Scientific’s vehicle data acquisition (DAQ) systems have a proven history of operating at the edge of performance in the vehicle testing environment. This includes extreme and repetitive temperature testing cycles, remote over-the-road testing, and environmental fatigue testing. Systems typically measure temperature, pressure, loads, and strains; and they monitor the vehicle data bus with general-purpose Controller Area Network (CAN) channels. Our systems are rugged, versatile, portable, and reliable. They are compatible with a wide variety of sensors with multiple wireless and wired communication capabilities including cellular, Bluetooth, Wi-Fi, and Ethernet.
A distributed DAQ for vehicle testing lowers the total cost of instrumentation with shorter sensor cable lengths, reduced cable costs, fewer vehicle modifications, and decreased sensor installation time—all with less cable to route. This unique design also improves measurement fidelity with reduced signal interference because components are located closer to the point of measurement.

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 Vehicle Testing. 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.
We offer a full line of data acquisition systems. Scan rates can be programmed from every few hours to 100,000 times per second, depending on the system model. Measurement types, processing algorithms, and recording intervals are also programmable. Our systems can also store data transmitted from the vehicle's on-board computer via CANbus, allowing time-synchronized storage of vehicle computer data with the data acquisition system's independently measured data.
On-board 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. Our instruction sets also allow unattended measurement and control decisions based on time or conditional events.
Because our VDAS are compatible with almost every commercially available sensor, our systems give you the freedom to use the sensors that best meet your application. Most sensors connect directly to our dataloggers, eliminating costly external signal conditioning. Channel types include analog (single-ended and differential), pulse count, switched excitation, continuous analog output, anti-aliasing filter, and digital I/O.
Typical sensors used with our systems include: thermocouples, pressure transducers, pulse pickups, flow transducers, potentiometers, strain gages, load cells, digital switches, accelerometers, LVDTs, and tilt sensors. Our configurable dataloggers, the CR9000X-series, allow you to choose modules with the channel types that best fit your application. The number and type of channels on most of our VDAS are expandable using multiplexers and other measurement peripherals.
On-site communications interfaces for retrieving, storing, and displaying data include direct connection to a PC or laptop, PC cards, storage modules, and a datalogger keyboard/display. A heads-up-display is also available for data display when driving a vehicle. Telecommunication options include short-haul, telephone (landline, cellular, and voice-synthesized), radio frequency, multidrop, and satellite.
Our PC-based support software simplifies the entire data acquisition process, from programming to data retrieval to data display and analysis. Robust error-checking ensures data integrity. We can even help you post your data to the Internet. RTDAQ is a full-featured package that is included with the CR9000X systems. RTDAQ is also compatible with our CR1000, CR3000, CR800, and CR850 dataloggers, although the software is purchased separately.
RTDAQ features include:
