The Series 7000 Ruggedized Ethernet DAS brings new capabilities and levels of performance to transducer data acquisition. The ruggedized system is designed for installation in wind tunnels, engine test stands and other facilities where it is desired to locate the DAS on or near the test article, reducing installation and cable costs while improving signal quality and reliability. Each unit is a network appliance which conditions, amplifies and digitizes outputs from transducers. Multiple units are easily combined and distributable for larger installations. Real-time temperature Compensation of gain offset and Excitation Voltage, quality signal conditioning with high gain and a 24-Bit A/D per channel provide a high accuracy and high resolution DAS that will perform across a wide operating range.
Pacific’s Ruggedized Series 7200 brings a brand new look to strain gage and transducer data acquisition. A network appliance, each module conditions, amplifies and digitizes the outputs of up to sixteen strain gage, bridge or voltage transducers. The rugged enclosure is designed for installation in wind tunnels, engine test stands and other facilities where it is desired to locate the DAS close to the test article, ultimately reducing installation and cable costs as well as improving signal quality and reliability.
Fully self-contained, the 7200 provides transducer excitation, bridge completion and balance. The transducer output is amplified, filtered to remove signal components that could produce alias errors and digitized to 24-bit resolution. The digitized transducer output is digitally processed providing multiple sample rates, an 80 dB/octave FIR filter and 32-bit floating point output format in millivolts referred to input, millivolts referred to output or user defined engineering units.
Three models are available that differ in their excitation and signal conditioning capabilities. Model 7216 for strain gage and bridge transducers has programmable voltage excitation, bridge completion for 120 and 350 Ohm strain gages, shunt calibration and automatic balance. Model 7220 is similar but provides regulated power for transducers with internal electronics. Model 7218 is for voltage inputs. The amplified transducer signals are digitized, processed and output at 10 to 24,000 samples per second, as selected for individual channels. A digital signal processor (DSP) provides low-pass filtering selectable from 10 Hz to 3,000 Hz with 80 db/octave roll-off.
Each module has a 100BaseT Ethernet interface for control and data output, which simplifies system wiring and provides remote and distributed operation. IRIG time may be employed to synchronize sampling on multiple modules within 10 microseconds, or a TTL timing may be used to achieve better than 1 microsecond time alignment. Multiple modules with up to 4,096 channels may be connected on a single Ethernet LAN.
The module enclosure features interchangeable end plates that provide fully sealed, ambient air or forced air cooling. Forced air cooling provides the capability to operate over a wide temperature range according to application requirements. Occupying less than 500 cubic inches and weighing less than 14 pounds, the 7200 modules can be installed in locations previously not suitable for data acquisition systems. The Ethernet interface and IRIG timing make it easy to distribute Bricks throughout the test facility, minimizing sensor cabling and installation costs.
The 7200 does not sacrifice performance for size or portability; it features higher accuracy than most systems designed for a laboratory environment. For the 7216, accuracy is better than 0.025% for gains up to 200 and 0.05% for gains above 200 over the temperature range -20°C to +50°C, which can be extended to higher temperatures by forced air cooling.
Series 7200 is supported by Pacific’s PI770 software that provides a ready-to-run application and an SDK for user program development. Calibration and performance verification is accomplished by PANEL72 Maintenance and Calibration software. The ACS2000 Automatic Calibration System automates performance verification and periodic instrument calibration.
Pacific’s Ruggedized Series 7300 increases the bandwidth and sample rates of the popular 7200 ruggedized data systems.
