Resonant acoustic emission sensor with high sensitivity, but the frequency response range is relatively narrow, but their prices are lower and higher sensitivity and is widely used.
PXR series acoustic emission sensors since November 2006 part adopts imported PZT sensor, as PXR03 type acoustic emission sensor successful upgrading in October 2008, at this point, PXR full range of acoustic emission sensors are all adopt imported PZT sensor.
Japan is the world famous piezoelectric ceramic producing area, the PZT material and processing technology has the world leading level, PXR acoustic emission sensor adopts the PZT sensor, in many aspects, such as sensitivity, consistency, temperature stability has obvious advantages.
Frequency response curve for a part of sensor:
PXR15 Frequency response curve for resonant acoustic emission sensor
PXR30 Frequency response curve for resonant acoustic emission sensor
PXR07 Frequency response curve for resonant acoustic emission sensor
PXR04 Frequency response curve for resonant acoustic emission sensor
PXR03 Frequency response curve for resonant acoustic emission sensor
PXR02 Frequency response curve for resonant acoustic emission sensor
