Nuclear power plants utilizing vibration monitoring ensure continuous power generation and safety for personnel and equipment, while also helping to prevent radiation leaks into the environment. Expensive and crucial machinery including cold water feed pumps, pressurized water reactors, and steam generators can operate more efficiently as a result of condition monitoring. Wilcoxon’s radiation-hardened sensors meet specific requirements for reliability of monitoring equipment in nuclear evironments. The side-exit 797R mounts in any orientation and can be exposed to 1 x 10⁷ RADs without degradation of signal performance, making it ideal for nuclear environments.
