R3a - 30 kHz Low Frequency AE Sensor
The R3a sensor cavity is machined from a solid stainless steel rod, making the sensor extremely rugged and reliable. The ceramic face electrically isolates the sensor from the structure to assure a low noise operation. Most low frequency AE sensors are relatively large. However, the R3a sensor has the same compact size as our other Alpha series sensors and boasts a low frequency, 30 kHz resonant response. This feature makes it extremely useful in tight areas that require a low frequency sensor for testing. The Alpha series family of sensors features SMA connectors versus the Microdot connectors found on MISTRAS' RXX series of passive sensors. The alpha series includes R3a, R6a, R15a, R30a, and WSa sensors.
