Curtiss-Wright - Model N9004 -Thermowell Mounted Fast Time Response RTD Assembly

The model N9004 fast time response RTD is designed to be installed in a compatibly designed thermowell for rapid detection of temperature changes in the Hot and Cold legs of the reactor coolant loops (RCS) of PWRs (pressurized water reactors). The N9004 RTD is currently installed in many operating PWR nuclear plants, with some of the original installations occurring in the early 1980’s. There is little drift of either calibration or time response associated with normal operating conditions. Thus, the RTD assembly has low maintenance costs. Also, due to unique design features, ALARA amounts are reduced during installation and removal, especially when a Quick Disconnect Connector (QDC) is used.
