SIEMENS SITRANS LVL200 Process Instrumentation 

Level Measurement Point Level New & Original

 

 

 

SITRANS LVL200 is a standard vibrating level switch for use in all liquid and slurry applications such as overflow, high, low, 

and demand applications, as well as pump protection. For use in SIL-2 applications. SITRANS LVL200 is a level 

switch designed for industrial use in all areas of process technology and can be used with liquids and slurries. 

With a tuning fork insertion length of only 40 mm (1.57“), SITRANS LVL200 can be mounted in small pipes and applications with confined space. 

The LVL200 can be used to measure products with a minimum density of >0.5 g/cm³ (0.018 lbs/in³). 

The LVL200 can be used in difficult conditions including turbulence, air bubbles, foam generation, buildup, or strong external vibration. 

SITRANS LVL200 continuously monitors faults via frequency evaluation, providing early detection of strong 

corrosion or damage on the tuning fork, loss of vibration, or a line break to the piezo drive. 

The tuning fork is piezoelectrically energized and vibrates at its mechanical resonance frequency of approx. 1200 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, directly operating connected devices. 

Key Applications: For use in liquids and slurries, for level measurement, overfill, and dry run protection.

 

Benefits

  • Functional Safety (SIL 2). Device suitable for use in accordance with IEC 61508 and IEC 61511

  • Hygienic process connections

  • Suitable for API 2350

  • Optional remote test signal conditioner

 

Application

SITRANS LVL200 is a level switch designed for industrial use in all areas of process technology and can be used with liquids and slurries. 

With a tuning fork insertion length of only 40 mm (1.57 inch), SITRANS LVL200 can be mounted in small pipes and applications with confined space. 

The LVL200 can be used to measure products with a minimum density of > 0.5 g/cm³ (0.018 lb/in³). 

The LVL200 can be used in difficult conditions including turbulence, air bubbles, foam generation, buildup, or external vibration.

SITRANS LVL200 continuously monitors faults via frequency evaluation, providing early detection of strong corrosion or damage on the tuning fork, loss of vibration, or a line break to the piezo drive.

The tuning fork is piezoelectrically energized and vibrates at its 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, directly operating connected devices.

The optional signal conditioner provides a remote test feature to ensure continuous product reliability.
