The Micro-Measurements System 7000 is a StrainSmart Data Systems and Software product for data acquisition, conditioning, reduction, and presentation of measurement data from strain gages and related sensors for stress analysis and structural materials testing. The system 7000 is built upon the years of experience gained since the introduction of Systems 4000, 5000, and 6000 by continuing to provide a complete hardware/software approach to data acquisition, reduction, and presentation for strain gages (strain gauges) and related sensors for stress analysis testing.

FEATURES

• Stable, accurate, low-noise signal conditioning
• Measurement accuracy ±0.05%
• Measurement resolution 0.5 microstrain
• Individual input cards for strain gage (strain gauge) and strain-gage-based transducers, thermocouples, and sensors with high-level voltage outputs
• Electronically selectable, built-in bridge completion for 120-, 350-, and 1000-ohm strain gages (strain gauges)
• Virtually unlimited number of channels in increments of 8 channels (Contact Applications Engineering for details)
• Maximum scan rate of 2048 samples per second
• Self calibration traceable to NIST standard
• Simultaneous sampling with anti-aliasing filter and analog-to-digital conversion for each channel
• Selectable digital filtering of measurement signals
• High-speed Ethernet network interface
• Remote Utility includes capability for acquiring data without connection to a computer (field upgradeable)

System 7000 hardware is designed to incorporate all the features required for precision strain measurement in a high channel density enclosure. Strain gages (strain gauges), strain-gage-based transducers, thermocouples, and other sensors with high level voltage outputs can be intermixed in groups of eight (8) by choosing the appropriate sensor card for up to 128 channels in a 4U height, 19-inch rack-mountable scanner (7000-128-SM). The Ethernet interface allows flexible positioning of scanners, and multiple scanners can easily be synchronized using a single sync cable (maximum length 100 meters). A system can be configured with virtually an unlimited number of sensors.

System 7000 is a high performance data acquisition instrument with measurement accuracy of ±0.05% of full scale. Each sensor card employs a 24-bit analog to digital converter enabling 0.5 microstrain resolution. Scan rates up to 2048 samples per second are available for simultaneous reading of all sensor inputs. A combination of analog and flexible Finite Impulse Response (FIR) filters are available to provide adequate anti-alias filtering at all scanning rates. Each sensor card has high-capacity nonvolatile data storage capability. Electronically selectable bridge completion resistors allow the user to choose between 120-, 350-, and 1000-ohm strain gages (strain gauges) through software selection.

System 7000 is capable of self-calibration with a removable calibration reference (7000-SM-VC). Calibration can be performed anywhere and there is no need to return the entire system to the factory for calibration. Down-time while waiting for calibration is essentially eliminated.
