The vibrating level switches in the LBV301 product family can be relied upon to signal full, empty, or demand states in bulk materials. The monoprobe design prevents bulk materials from jamming. The rugged stainless steel sensor design is piezo-electrically energized. When the probe is covered with bulk materials, the change in vibration amplitude is reliably detected and converted into a switching signal. As the monoprobe is easy to clean, the sensors are even suitable for use in the food industry. While the LBV311 compact device is used for horizontal mounting, the LBV321 cable-extended switch and the LBV331 tube-extended switch are used for vertical mounting in silos and bridge sensing ranges of up to 80 m and 6 m respectively. With a variety of process connections for hygienic applications and several electronic variants, the LBV301 can be used for nearly all applications, even in explosive atmospheres.
