C-4 TEDS 928693 Appendix C
The Basic TEDS contains the manufacturer’s identification, model identification, version letter, and the serial
number, which are common to all types of sensors. The Standard TEDS, however, contains data unique to the
sensor’s principle of operation. For instance, a piezoelectric accelerometer differs from a strain gage load cell, so the
Standard TEDS EEPROM contains some common and some unique information. Both sensor TEDS list Calibration
Date, Measurement Range, and Electrical Output, but they differ in as many as 12 other parameters. The
accelerometer has 6 parameters that the strain gage lacks, and the strain gage has 6 parameters the accelerometer
lacks. The User Area contains information such as Sensor Location, Calibration Due Date, and Calibration Table.
