SITRANS LC300
SITRANS LC300 is a cost-effective instrument for level measurement in applications such as
the processing of food and beverages, pharmaceuticals, detergents and pet food. It performs
in liquids, bulk solids and slurries, including viscous (conductive or non-conductive) materials,
even in challenging environments involving vapour and dust.
LC300 is a 2-wire instrument combining a sophisticated, yet easy-to-adjust, microprocessor
transmitter with field-proven probes.
SITRANS LC300 Outputs
• 4 – 20 or 20 – 4 mA, 2-wire current loop circuit
• Isolated from the measurement circuit
• Current signalling according to NAMUR NE 43
