SITRANS LVL100 Level Switch

The SIEMENS SITRANS, LVL100 level switch, is a compact vibrating level switch for use in liquid applications such as overflow, high, low and demand applications, as well as pump protection. It is ideal for use in confined spaces.

The SITRANS LVL100 level switch is a compact level switch designed for industrial use in all areas of process technology and can be used with liquids and slurries. With an insertion length of only 40 mm (1.57“), SITRANS LVL100 can be mounted in small pipes and confined space applications. It is also virtually unaffected by the chemical and physical properties of the liquid. The LVL100 can also be used in difficult conditions including turbulence, air bubbles, foam generation, buildup, or strong external vibration.

The tuning fork is piezoelectrically energised and vibrates at its mechanical resonance frequency of approximately 1200 Hz. The vibration frequency changes when the medium covers the tuning fork. This change is detected by the integrated oscillator and converted into a switching command. The integrated electronics evaluate the level signal and output a switching signal, directly operating connected devices.
