Nonfunctional module/sensors combo eases measurement tasks

To be able to respond rapidly on changing tasks in measurement technology, IPETRONIK supports the use of TEDS sensors (Transducer Electronic Data Sheet) with a Lemo-2B-version of their multifunctional module Sx-STG. This IEEE-1451.4 defined plug & measure standard contains information about the identification number of the sensor, the calibration and the supplier. It enables the flexible, faultless adjustment of the module on new sensor parameters.

The Sx-STG detects IEEE-1451.4 Class 2 sensors (multi-wire connections, e.g. as bridge sensors) automatically when putting on 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 comfortably with the measuring data acquisition software IPEmotion.

“Everywhere, where complex measurements and measurements with frequently changing measurement setups or many measurement channels are performed, TEDS plays out its advantages”, explains Harry Stoerzer, leader of application and support at IPETRONIK. “Besides the easy and fast setup of measuring chains, the “electronic data sheet” guaranties dependably correct measuring data at every measurement task. TEDS is suitable for the vehicle development and production as well as for applications on-site at the customer.” Sx-STG is a fast eight channel multi analogue measuring module with sensor supply for various applications inside the car cabin. The compact module supports three different signals according to measuring input: voltage, IEPE (Integrated Electronics Piezo Electric) resp. ICP® (Integrated Circuit Piezoelectric) as well as strain gage sensors.

Eight analogue inputs cover measuring ranges with voltages of ±0.01 V up to ±50 V. Each input has its own configurable sensor supply of ±15 V with up to ±45 mA. The measuring data output happens on Ethernet or on the CAN bus.

The module has an anodised aluminium case in accordance with protection type IP54 and a size of 75 mm x 119 mm x 185 mm (W x H x D). It operates in a temperature range of -40 °C up to +85 °C. Sx-STG operates within a supply voltage range from 9 VDC up to 36 VDC. All measuring inputs, Ethernet/CAN and the module supply are completely galvanically isolated.
