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. 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. 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.

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:
• Reduced configuration time by eliminating manual data entry
• Better sensor tracking by storing data sheets electronically
• Improved accuracy by providing detailed calibration information
• Simplified asset management by eliminating paper data sheets
• Reliable sensor location by identifying individual sensors electronically
PSD Specifics
All standard TEDS devices contain a basic 2-point calibration. TEDS devices can also
optionally hold more than one extended calibration table (template ID=40 (multi-
point calibration) or template ID=41 (polynomial calibration). When you first connect
a new TEDS device to the PSD a message will be displayed stating that a new TEDS
device has been detected and that default settings have been used.
