Sick's LBV330 range of tuning forks are level sensors which signal full, empty or demand states in bulk solids. The LBV330 sensors are rugged, reliable and highly accurate.
The tuning fork reacts to changes in density, and thus operates independantly of silo shape, tank material, container structure or bulk material. The sturdy fork is made of stainless steel and is oscillated piezo-electrically.
The actual resonance of the fork changes significantly when it is covered and triggers a switching signal.
The LBV330 range of level sensors are available with a wide variety of thread and flange connections and several electronic variants allowing for the LBV330 range to suitable for almost all applications even in potentially explosive atmospheres.
The LBV330 has a tube extension for vertical mounting to bridge switching distances of up to 60m.
