What's new in smart weight-and-cable bin level sensors
This article covers the latest generation of smart weight-and-cable bin level sensors. After explaining how the smart sensors work and how they overcome a conventional sensor’s limitations, the article describes new smart sensor features that provide more reliable measurement performance and reduce the sensor’s maintenance requirements.
Conventional weight-and-cable bin level sensors -- also called plumb bobs and yo-yos -- have been used for many decades to monitor material levels in storage vessels. The sensor lowers a weight (also called a bob or probe) on a cable to the material surface in a storage vessel and then raises the weight as the distance it travels is measured and related to the material level. Plastics processors, food manufacturers, concrete producers, and many other bulk solids processors use the sensor to improve their raw material inventory management, production efficiency, and plant safety.
