The intention of the standard is to do away with paper-based sensor data sheets by digitally storing data such as scaling parameters, calibration and sensor vendor information on an embedded EEPROM chip, simplifying sensor configuration and eliminating the risk of data entry errors.
The PC-based test firm’s NI-DAQmx 7.2 software incorporates TEDS reader functionality. There are also three hardware products: NI SC-2350, NI BNC-2096 and SCXI-1314T, which include the circuitry required to communicate with TEDS. This will support plug and play sensors for systems using SCC and SCXI signal conditioning or dynamic signal acquisition (DSA) devices.
The NI SC-2350, a carrier for NI SCC signal conditioning modules, is compatible with all existing SCC modules and includes a built-in TEDS reader that engineers can use to take measurements such as temperature, pressure and strain.
The NI BNC-2096, a 19-inch rack-mountable terminal block for smart TEDS accelerometers and microphones, is a front-end for IEPE signal conditioners such as the NI PXI-4461 24-bit analogue input/output data acquisition module, the PXI-4472 8-channel DSA module and the SCXI-1530/1 4-channel accelerometer input module.
The NI SCXI-1314T is a front-mounting terminal block for the NI SCXI-1520 bridge sensor input module and delivers TEDS reader capabilities to SCXI-based data acquisition systems measuring bridge-based sensors such as load cells and pressure sensors.
