IPETRONIK supports the use of TEDS (Transducer Electronic Data Sheet) sensors with a Lemo-2B-version of its multifunctional module Sx-STG, under the IEEE-1451.4 defined plug-and-play standard. It enables the flexible, faultless adjustment of the module on new sensor parameters. The Sx-STG detects, e.g., IEEE-1451.4 Class 2 sensors (multi-wire connections, e.g. as bridge sensors) automatically and reads the sensor-specific data via the TEDS connection; the user does not have to enter the scaling data manually. Channel-specific settings such as operation mode, filter, excitation voltage, sampling rate, etc. are performed with the data-acquisition software IPEmotion. TEDS is suitable for vehicle development and production as well as for on-site applications at the customer. Sx-STG is an eight-channel multi analog measuring module with sensor supply for various applications inside the vehicle cabin. The module supports three different signals according to measuring input: voltage, IEPE (Integrated Electronics Piezo Electric) or ICP (Integrated Circuit Piezoelectric), as well as strain gauge sensors. Eight analog inputs cover measuring ranges with voltages of ±0.01 to ±50 V. Each input has its own configurable sensor supply of ±15 V with up to ±45 mA. The measuring data output occurs via Ethernet or the CAN bus. It operates in a temperature range of -40 to +85°C (-40 to +185°F). Sx-STG operates within a supply voltage range from 9 to 36 VDC.
