SITRANS LVL200 is a standard vibrating level switch designed for industrial measurement of liquids and slurries in applications such as overflow, high, low, and demand processes, as well as pump protection. Appropriate for use in SIL-2 applications. With a tuning fork insertion length of only 1.57″ (40 mm), SITRANS LVL200 can be mounted in small pipes and applications with limited space.
The SITRANS 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, build-up, 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.
