Performance assessment of Class 1E pressure transmitters subjected to environmental stresses
Research has been conducted within the Component Assessment Program to evaluate the failure and degradation modes of unaged instruments exposed to environments exposed to environments within and beyond the design basis. Current qualification test requirements as they relate to electronic components in containment were also evaluated. This paper summarizes the salient findings of an experimental evaluation of pressure transmitter performance in harsh environments. The test matrix exposed five ITT Barton Model 763, 0-1000 psig, 4-20mA pressure transmitters to five separate environments: (1) simulated Loss of Coolant Accident (LOCA) steam condition alone, (2) temperature alone, (3) radiation alone, (4) simultaneous radiation and LOCA temperature (no steam) conditions, and (5) simultaneous radiation and simulated LOCA steam conditions. Unaged equipment was tested to establish a baseline performance.
