Germantown, MD—Nuclear power plants utilize vibration monitoring to ensure continuous power generation and safety for personnel and equipment, and prevent radiation leaks. Expensive and crucial machinery including cold water feed pumps, pressurized water reactors, and steam generators operate more efficiently as a result of condition monitoring. Meggitt has developed new radiation-hardened vibration sensors and cable assemblies to meet specific requirements for the reliability of monitoring equipment in nuclear evironments. The conditions of nuclear power plants can cause deterioration of equipment. Wilcoxon accelerometers are designed to perform continuously in harsh environments without degradation. Mechanical components used in Wilcoxon 793R series sensors were subjected to gamma radiation exposure in excess of 2 x 107 RADs without degraded sensor performance. Wilcoxon radiation-hardened sensors can tolerate a cumulative radiation exposure of 1 x 107 RADs, still meeting original manufacturing specifications, and are operable up to 248°F (120°C). Model 797R is a side exit, low profile IsoRing accelerometer with tight sensitivity tolerance of 100 mV/g, ±5%. Its velocity transducer houses ultra low-noise electronics for clear signals at very low vibration levels, and has a frequency range of 2 Hz to 7 kHz.
