EX1629-001 High-performance Remote Strain Gage Measurement Unit OVERVIEW The VXI Technology EX1629-001 Remote Strain Gage Measurement Unit simplifies stress and fatigue testing of large mechanical structures such as airframes and launch vehicles. Ethernet control allows for remote operation and easy connection to the host computer. • A single system that can provide high-quality static or high speed strain measurements in one unit • Airframe structural and fatigue test • Rocket and satellite structural test • Wind tunnel flight load test • General purpose bridge measurements The VXI...

EX1629-001 High-performance Remote Strain Gage Measurement Unit 10,000+ channels can be combined and measured in an EX1629-001 system The EX1629-001 can operate independently, or for large data acquisition applications multiple EX1629-001s can be synchronized together via an external trigger bus. This design allows for numerous units to be controlled by a single host computer by utilizing a programmable master slave relationship. The trigger input includes a D-Sub connector which accepts TTL logic level input and has programmable trigger polarity. There has never been a strain measurement...

EX1629-001 High-performance Remote Strain Gage Measurement Unit R educed C ost for S trai n G age F ie l d W iri n g Extensive testing has resulted in the qualification of the standard RJ-45 telecom connector as the ideal low-cost connector for strain gages. Not only are these connectors reliable, but also low-cost construction of custom length cables is readily available. Re-configuration or replacement of strain gage connections is as easy as connecting a telephone. For static load testing, there is an additional benefit. The design of the EX1629-001 allows it to be placed close to the...
