Transducer Electronic Data Sheet

A Transducer Electronic Data Sheet (TEDS) is a standardized method of storing transducer

s or actuator
s) identification, calibration, correction data, and manufacturer-related information. TEDS formats are defined in the IEEE 1451
set of Smart transducer
interface standards developed by the IEEE Instrumentation and Measurement Society’s Sensor Technology Technical Committee that describe a set of open, common, network-independent communication interfaces for connecting transducers to microprocessors, instrumentation systems, and control/field networks.
One of the key elements of the IEEE 1451 standards is the definition of TEDS for each transducer. The TEDS can be implemented as a memory device attached to the transducer and containing information needed by a measurement instrument or control system to interface with a transducer. TEDS can, however, be implemented in two ways. First, the TEDS can reside in embedded memory, typically an EEPROM
, within the transducer
itself which is connected to the measurement instrument or control system. Second, a virtual TEDS can exist as a data file accessible by the measurement instrument or control system. A virtual TEDS extends the standardized TEDS to legacy sensors and applications where embedded memory may not be available.
Transducer
A transducer is a device that converts one type of energy to another. Energy types include electrical, mechanical, electromagnetic , chemical, acoustic or thermal energy. While the term transducer commonly implies the use of a sensor/detector, any device which converts energy can be considered a...

Sensor
A sensor is a device that measures a physical quantity and converts it into a signal which can be read by an observer or by an instrument. For example, a mercury-in-glass thermometer converts the measured temperature into expansion and contraction of a liquid which can be read on a calibrated...

Actuator
An actuator is a type of motor for moving or controlling a mechanism or system. It is operated by a source of energy, usually in the form of an electric current, hydraulic fluid pressure or pneumatic pressure, and converts that energy into some kind of motion. An actuator is the mechanism by which...

EEPROM stands for Electrically Erasable Programmable Read-Only Memory and is a type of non-volatile memory used in computers and other electronic devices to store small amounts of data that must be saved when power is removed, e.g., calibration...
