The Glass Bob sensor measures silica sand (also called frac sand) levels in silos, tanks or bins. It is often used instead of the traditional steel spike bob, when there is need to ensure that metal parts do not enter the production process. Silica sand measurement is not an easy process, as the entire production process can come to a stop if a sensor gets stuck in the bin material and enters the mechanical systems. The problem with production involves additional expenses in terms of repairs and time wasted.
The advantage in using the Glass Bob Sensor is that even if the glass gets crushed during processing, it does not damage the material or equipment as glass is mainly sand and gets mixed up with the product being processed. This helps eliminate the risk of wasted time and money. It can also save the effort of climbing into bins for manual measurements, if anything goes wrong. The sensor is almost like an automated tape measure that takes measurements at pre-set intervals or when needed. It measures by counting pulses, making it highly accurate.
