Crystal Holder and Feedthrough
The application determines the correct choice of Quartz Crystal sensor. The sensor determines compatible feedthroughs and cabling. The chamber determines the appropriate feedthrough and flange. The feedthrough is the air-to-vacuum connection between the sensor and the oscillator. The feedthrough transfers the quartz crystal’s piezo-electric vibrations to the oscillator via a short coaxial cable. The oscillator conditions the signals and transfers them to the monitor via another coaxial cable. The monitor then measures, interprets and displays the thickness, rate and frequency of deposition.
