SITRANS LC500 Overview
SITRANS LC500 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.
SITRANS LC500 combines a sophisticated, easy-to-adjust transmitter with a measurement
electrode and process seal selected from a range of options
applications. The advanced electronics and integrated local display provide for one-step
calibration without interrupting the process, and the probe shield design eliminates the need
for frequent recalibration.
SITRANS LC500 can be used as a level controller, by connecting the mA output and/or the
solid-state switch to a relay, and activating a pump via an auxiliary power circuit.
The SITRANS LC500 is equipped with:
•
Smart 2-wire transmitter
•
Remote adjustable commissioning / control capabilities via HART
•
Analog (2-wire) 4 to 20mA / 20 to 4 mA output
•
Solid-state and Current detection (4 or 20 mA / 20 or 4 mA, two-state
functionality)
•
Adjustable hystereses on/off for solid-state output and for current signal
•
Damping functionality
•
Signal current (measurement/detection) according to NAMUR NE 43
•
Integrated local display for commissioning and services activities
•
Full range of local/remote diagnostic facilities
•
Polarity-insensitive current loop
•
Integrated zener safety barrier
