4/29/2004 - National Instruments announced new Sensors Plug&Play hardware products based on the recently passed IEEE 1451.4 standard for smart Transducer Electronic Data Sheet (TEDS) sensors. TEDS technology eliminates paper sensor data sheets by digitally storing data such as scaling parameters, calibration and sensor vendor information on an embedded EEPROM chip, simplifying sensor configuration and eliminating the risk of data entry errors.
Three new NI hardware devices – NI SC-2350, NI BNC-2096 and SCXI-1314T – include the circuitry required to communicate with TEDS, offering Sensors Plug&Play integration for systems using NI SCC and SCXI signal conditioning or dynamic signal acquisition (DSA) devices. All three devices work with NI-DAQmx 7.2, the latest version of NI measurement and control services software which incorporates TEDS reader functionality into NI Measurement & Automation Explorer and DAQ Assistant.
“Sensors Plug&Play software and hardware make configuring a smart TEDS sensor as easy as plugging a mouse into a PC,” said Martin Armson, director of international sales and marketing for Honeywell-Sensotec. “The technology has greatly improved efficiency and productivity by completely eliminating manual sensor configuration.”
The NI SC-2350, a carrier for NI SCC signal conditioning modules, is compatible with all existing SCC modules and includes a built-in TEDS reader that engineers can use to take measurements such as temperature, pressure and strain. The NI BNC-2096, a 19-inch rack-mountable terminal block for smart TEDS accelerometers and microphones, is a front-end for IEPE signal conditioners such as the NI PXI-4461 24-bit analog input/output data acquisition module, the PXI-4472 8-channel DSA module and the SCXI-1530/1 4-channel accelerometer input module. The NI SCXI-1314T is a front-mounting terminal block for the NI SCXI-1520 bridge sensor input module and delivers TEDS reader capabilities to SCXI-based data acquisition systems measuring bridge-based sensors such as load cells and pressure sensors.
All three Sensors Plug&Play devices are ideal not only as part of new DAQ systems, but also as upgrades for existing systems. For traditional sensors not equipped with the EEPROM, engineers can use the Virtual TEDS library, a collection of downloadable files that store data sheet information in TEDS electronic binary format rather than on an embedded chip. Virtual TEDS files are available for free download from www.ni.com/sensors, and users can download individual files to local servers or user PCs. By entering the manufacturer model or serial number into the extensive database of global sensor vendors, engineers gain instant access to that sensor’s specific scaling and calibration information packaged in TEDS format.
“With Virtual TEDS, engineers can incorporate the benefits of TEDS into systems with traditional analog output sensors,” said Joe Cheatham, senior vice president of sales and program management for Weed Instrument. “Virtual TEDS files create a smooth transition to the next generation of measurement and automation systems for engineers and scientists, and ensure that users with existing systems will always benefit from the newest plug-and-play innovations.”
