Abstract

A miniaturized multi-channel (16) thermocouple DAQ module was designed and tested. The connector and electronics configuration allows positioning of low-noise (<; 1 μv) signal conditioning close to the test area and transmits the data on a high speed Ethernet to a central computer for analysis. It uses the IEEE 1451 smart transducer (open) standard and Transducer Electronic Data Sheet (TEDS) to achieve the plug and play specification and also a low error rate. A precision time stamp using IEEE 1588 is provided.
