© Siemens AG 2016 Level Measurement Point level measurement - Vibrating switches SITRANS LVL100 ■ Overview ■ Configuration Horizontal mounting Switching point Switching point (recommended mounting position, particularly for adhesive applications) Vertical mounting 13 (0.51) SITRANS LVL100 is a compact vibrating level switch for material detection in liquid and slurry applications such as overflow, high, low and demand applications, as well as pump protection. It is ideal for use in confined spaces. 13 (0.51) Switching point with lower density Switching point [approx. 13 (0.51)] ■ Benefits • Proven vibrating level switch technology for liquids • Compact insertion length of 40 mm (1.57 inch) for confined space applications • Fault monitoring for corrosion, loss of vibration, or line break to the piezo drive • Integrated test function to confirm correct operation ■ Application SITRANS LVL100 is a compact level switch designed for industrial use in all areas of process technology and can be used for material detection with liquids and slurries. With an insertion length of only 40 mm (1.57 inch), SITRANS LVL100 can be mounted in small pipes and confined space applications. It is virtually unaffected by the chemical and physical properties of the liquid. The LVL100 can be used in difficult conditions including turbulence, air bubbles, foam generation, buildup, or external vibration. The tuning fork is piezoelectrically energized and vibrates at a mechanical resonance frequency of approximately 1 200 Hz. The vibration frequency changes when the tuning fork is covered by the medium. 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 to connected devices. • Key Applications: for use in liquids and slurries, for level measurement, overfill, and dry run protection Switching point with higher density Horizontal mounting in viscous or adhesive applications Moisture protection 30 (1.18) NOTE: Welded socket for flush mount optional. Ensure cable gland faces downward to avoid water ingress.
