General Purpose, 800 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 making for a simpler and more robust design. • Dramatically increased thickness of the ceramic shoe for better mechanical stability. • Distance from the bottom of the ceramic shoe to the bottom edge of sensor cavity increased for better insu lation resistance and ground avoidance. Completely enclosed crystal for RFI/EMI immunity • 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. Sensor to Preamp Cable Application High frequency AE sensors such as the R80α are often used in a high noise environments on applications such as brittle crack detection and processing of AE signals with high frequency components. Frequency response of the R80α. Calibration based on ASTM E1106; Calibration based on ASTM E976.
