What is TEDS?
"Plug and play sensor hardware and software make configuring a smart TEDS sensor as easy as plugging a
mouse into a PC. The technology has greatly improved efficiency and productivity by completely eliminating
manual sensor configuration."
Basic concept
TEDS is at the heart of the new universally accepted IEEE 1451.4 standard for delivering Plug and Play capabilities
to analogue measurement and test instruments. In essence, information in a Transducer Electronic Data Sheet
provides interfacing devices with the critical sensor calibration information in order to perform accurate and
precise measurements every time.
TEDS works in a similar way in which USB computer peripherals immediately work as they are connected. TEDS
enabled equipment may be swapped and changed without recalibration, saving time and money.
TEDS holds information such as a sensor manufacturer, model and serial numbers, and more importantly all the
calibration settings determined by the manufacturer.
How it works
Plug and play is a data acquisition technology that can simplify the configuration of automated measuring systems
by making a sensor’s unique identification data available electronically. As implemented according to IEEE 1451.4,
data in the form of a transducer electronic data sheet (TEDS) 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.
