General Purpose, 500 kHz Resonant Frequency Acoustic Emission Sensor Operating Specifications The Alpha series family of sensors features SMA connectors versus the Microdot connectors found on PAC’s RXX series of passive sensors. The Alpha series includes R3α, R6α, R15α, R30α R50α, R80α and WSα sensors. The major improvements in Alpha series over the RXX series include: • Use of the more popular SMA type of connector. • Cavity is machined from a solid stainless steel rod mak ing for a simpler and more robust design. • Dramatically increased thickness of the ceramic shoe for better mechanical stability. Completely enclosed crystal for RFI/EMI immunity • Distance from the bottom of the ceramic shoe to the bottom edge of sensor cavity increased for better insu lation resistance and ground avoidance. • Introduced a 30-degree angle at the bottom edge of the sensor cavity. All these improvements make the Alpha series sensors more robust, reliable and greatly reduce the possible grounding of the cavity to the structure caused by wet environment. Application This sensor is useful in very noisy plant and process monitoring applications and is particularly suited to such applications as welding monitoring and control.
