7. EDS is burned on an electrically erasable programmable read only memory EEPROM chip located on the sensor so when a properly adapted signal conditioner interrogates the sensor it can interpret the self identification data This technology provides a great benefit by eliminating the need for paper calibration sheets In addition it can simplify labeling and cabling problems as well as inventory control issues by letting you burn location data onto the chip when installing a sensor And because all sensors produced according to the standard will carry the same basic identically formatted self identification information you will be able to mix and match sensors and applicable signal conditioners across manufacturers Interface 9320 TEDS Ready Indicator Manual Issue 2 4 3 Advantages Plug and play sensors are revolutionizing measurement and automation With Transducer Electronic Data Sheets TEDS your data acquisition system can detect and automatically configure sensors This technology provides e Reduced configuration time by eliminating manual data entry e Better sensor tracking by storing data sheets electronically e Improved accuracy by providing detailed calibration information e Simplified asset management by eliminating paper data sheets e Reliable sensor location by identifying individual sensors electronically Introduction The 9320 Portable Strain Display Load Cell Force transducer readout is a microprocessor based portable in
