SITRANS LC 500
SITRANS LC 500 is a high performance 2-wire capacitance instrument for continuous level
and interface measurement in extreme or critical conditions. It uses a unique frequency-
based measurement system and patented Active-Shield technology to deliver highly
accurate, repeatable results. The measurement is unaffected by moisture, vapors, foam,
temperature and pressure variations, or material build-up around the mounting glands.
