سوییچ ویبره SIEMENS مدل SITRANS LVL100

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.
Benefits
• Proven vibrating level switch technology for liquids
• Compact insertion length of 40 mm (1.57 inch) for confined space
applications
• Available starting at 1/2" threaded process connections
• 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
