Model P3 is a digital electric portable (battery-powered) device whose principle of operation is based on converting input signals from primary transducers (quarter-bridge, half-bridge and full-bridge tensometric sensors) into digital form by means of ADC, further processing and displaying measurement results on the display. The field of application is precision measurements, measurements of deformations and stresses of materials and structures, automation of research and technological static and dynamic processes. Highly stable measuring circuits, adjustable power supply to the bridge, and a precision-mounted gage sensitivity coefficient ensure measurement accuracy of ± 0.1%. Data recorded in a user-definable range of up to 1 reads per channel per second is stored on a removable multimedia card and transferred via the USB interface to the host computer for later storage, compression and display by means of the supplied software. P3 can also be configured with control directly from a computer using separate software attached to each device.
The D4 is a portable, high-precision device for use with strain gauges and strain gauge transducers. The device has 4 channels for working with quarter-, half- and full bridges of strain gauges. Work with bridges of 120 Ohm, 350 Ohm, 1000 Ohm is foreseen.
D4 is controlled via USB. The software allows you to control using a personal computer based on Windows. The software supports up to six devices simultaneously.
Micro-Measurements System 7000 builds 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 and related sensors for stress analysis testing.
System 7000 hardware is designed to incorporate all the features required for precision strain measurement in a high channel density enclosure. Strain gages, strain-gage- based transducers, thermocouples, LVDTs, 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). A 32-channel scanner is also available (7000-32-SM). The Ethernet interface allows lexible positioning of scanners, and multiple scanners can easily be synchronized using a single sync cable (maximum length 100 meters). A system can be conigured with virtually an unlimited number of sensors; please contact our Applications Engineering Department for coniguration details.
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 lexible Finite Impulse Response (FIR) ilters are available to provide adequate anti-alias iltering 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 through software selection.
Several design features are provided to reduce total cost of ownership. 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. Input connectors are RJ-45 type and assembly time is fast using simple cable crimping tools. Sensor input cards all use common Analog Input Cards (Model 7003-8-A-I), which thereby allow users to interchange sensor input cards with analog input cards. Individual scanners can be separated and located near sensors to reduce sensor cabling costs.
A feature for acquiring data without a connection to a computer has been added. This Remote Utility Feature
is ield upgradable on units purchased prior to the introduction of this feature. With this feature, data can be collected then exported to other applications for analysis.
System 8000 from Micro-Measurements is a versatile, precision data acquisition instrument system intended for static and dynamic test and measurement applications.
The system includes a scanner with 8 channels of data acquisition. A 10’ crossover Ethernet cable is also included. The scanners may be used separately or up to 16 scanners can be used concurrently for a maximum of 128 channels.
Each channel can be conigured, via software, to
accept signals from strain gages or strain-gage-based transducers, thermocouples, or high level voltage sensors. Strain gage channels accept full-, half-, or quarter-bridge conigurations and have the required bridge completion components for 120-, 350-, and 1000- ohm bridges. Each scanner operates independently; multiple scanners are not synchronized.
The data is processed in a modern 24-bit digital signal processor and iltering is performed using Finite Impulse Response (FIR), multi-stage ilters. This provides excellent noise rejection and stability and unsurpassed measurement accuracy.
The Model 8000-8-SM Scanner communicates with a host personal computer (PC) via an Ethernet connection. Micro-Measurements StrainSmart® software is optimal for coniguring, controlling, and acquiring data from the System 8000. A Programmer’s Reference Kit provides documentation, programming examples, and instrument drivers to assist with custom software development.
StrainSmart® is a ready-to-use, Windows®-based software package for acquiring, reducing, presenting, and storing measurement data from strain gages, strain-gage-based transducers, thermocouples, temperature sensors, LVDTs, potentiometers, piezoelectric sensors, and other commonly used transducers.
It is designed to function seamlessly with a variety of Micro-Measurements instrumentation hardware, including System 7000 and System 8000. A unique version of this software is used to operate System 9000, called StrainSmart® 9000
