The WSα sensor is a single-ended, wideband frequency, Acoustic Emission sensor. Featuring a SMA connector within an integrated stainless steel cavity, the WSα is machined from a solid rod. A 30-degree angle at the bottom edge of the sensor cavity reduces the risk of electric shorts from the sensor cavity to conductive test surfaces. The WSα takes advantage of the general Alpha series (consisting of R3α, R15α, R30α R50α, R80α and WSα sensors) sensor features and the WD sensor's high sensitivity and wideband frequency range.
