What is TEDS?
TEDS is a tiny electronic chip that carries unique sensor information. The TEDS technology is described by the IEEE1451.4 standard. As the IEEE1451 is an internationally accepted standard, the TEDS technology not only works with components from one manufacturer but also with devices from different suppliers combined in one measurement chain. HBM was actively involved in the development of this standard and electronic transducer identification using TEDS.
All data in a TEDS chip is stored in templates, which are essentially tables where the sensor parameters are laid out. Several templates are available for different sensors, such as voltage sensors, bridge sensors (strain-gauge technology), or current output sensors.
When connecting a sensor featuring TEDS to a data acquisition system that can read a TEDS chip, the setup of the measurement chain is performed automatically. Typing errors are obviously not an issue with his technology and the setup time is substantially reduced.
This ensures accurate measurements, even with frequently changing measurement configurations and large numbers of connected transducers.
TEDS is beneficial for test and measurement applications in development laboratories as well as for manufacturing and production monitoring.
