Vibration gyro sensors sense angular velocity from the Coriolis force applied to a vibrating element. For this reason, the accuracy with which angular velocity is measured differs significantly depending on element material and structural differences. Here, we briefly describe the main types of elements used in vibration gyro sensors.

· Quartz sand is commonly used in the Indian glass industry for making container glass, flat glass, plate glass, specialty glass, fiberglass, bottles, table glassware, and other glassware. Quartz supplying industries such as Unique Crystal minerals LLP supply a large amount of quartz sand which is widely used in the Indian Glassmaking Industry.
Higher frequency radar can see a wider array of objects and will be more robust than an ultrasonic sensor in most applications, including outdoors. Radar-based sensors are also ideal for collision avoidance on board mobile equipment such as reach stackers, forklifts, and mining vehicles or port machinery such as carriers, handlers, and shippers.
