The Emerson PR6423/10R-030-CN is a radioactive radiation resistant non-contact eddy current displacement transducer designed for measuring position or shaft movement without contacting the target surface. Constructed for nuclear radiation zone 1 applications, this sensor enables non-contact measurement of static and dynamic shaft displacement, including axial and radial shaft displacement (position), shaft eccentricity, and shaft vibration (motion). It directly measures shaft motion and position on sleeve bearing machines where vibration signals are otherwise attenuated by the bearing oil film. The unit features a radioactive radiation resistant design suitable for turbomachinery, reactor coolant pumps, motors, pumps, fans, and blowers, and operates in conjunction with signal converters such as CON 011/91, 021/91, and 041/91.
