Customise a System
In addition to our standard systems available, many of the systems we provide are customised. Tell us what you need, and we’ll help you configure a system that meets your exact needs.
Instrumentation
We offer a variety of products that can be used to create systems for Vehicle Testing & Performance. 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.
More Details about Our Vehicle Testing & Performance Systems
Data Acquisition for Vehicle Testing
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.
Sensors for Vehicle Testing
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.
Data Retrieval
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.
Software
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:
- ShortCut Program Generator for easy-to-use, step-by-step programming assistance.
- Variety of windows for monitoring datalogger data in near-real time, including Fast Graph, Histogram Viewer, FFT Viewer, Table Monitor, and X-Y Plot.
- Historical display of data in time series, rainflow, level crossing, and FFT formats.
- Data collection in multiple data formats.
