WebMar 3, 2024 · Underground space engineering structures are generally subject to extensive damages and significant deformation. Given that composite rocks are prone to shear failure, which cannot be accurately monitored, the piezoelectric active sensing method and wavelet packet analysis method were employed to conduct a shear failure monitoring test on … WebQuartz crystal thickness monitors vary in size and complexity, but typically include a piezo-electric quartz crystal sandwiched between a pair of electrodes, a monitor for rate and thickness measurement and a controller to automate the process [1]. The quartz monitor crystal is created by applying electrodes on a thin quartz disc.
WebFrom time to time, we have encountered that some film thickness monitors are unable to properly maintain the resonance frequency the HT and RC Crystals require. As a result, these crystals will appear as “dead” or 0% health on the monitor status screen. This phenomenon can also be termed ‘mode skipping’ and is the result of a remote ... WebThe control unit has a digital readout, which displays coating thickness directly in nanometres, with a resolution of 0.1nm. A tooling factor can also be entered to compensate for differences in specimen and crystal position. The film thickness monitor features a measurement range of 0 to 999.9nm, and a display of crystal life.
