Weboscillating quartz monitor using a single quartz crystal, with two pairs of gold electrodes deposited on it. The possibility of using this arrangement was investigated by Van Empel et al (1971a, b). However, several commercial quartz crystal thickness monitors (Fox and Katz 1969) are also available in which two quartz crystals are used. WebQuartz crystal thickness monitor requires quartz crystals which are a consumable item used during the operation of the monitor. SPI offers the highest quality quartz crystals for this application. Dimensions: Crystals are 1/2" (12.5 mm) round and with a thickness of 12 mils (305µm/0. 305 mm) thick at the center.
