With a Vibrating-Type Level Sensor for Bulk Solids and Liquids, when the probe (either fork or rod) comes into contact with the medium, the vibration changes and the sensor outputs a command. This type level sensor is used as an overfill protection device or low-level indicator in liquids as well as in bulk solids. Other advantages include: setup possible without medium; and point-level measurement independent of installation position, pressure, temperature, foam, viscosity, and grain size.
