Introduction to the SITRANS LC 300

The SITRANS LC 300 is a cost-effective instrument for level measurement in high
accuracy 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.
The LC 300 is a 2-wire instrument combining a sophisticated, yet easy-to-adjust,
microprocessor transmitter with field-proven Pointek CLS 300 probes.
The electronic component contains the measurement module (driver) and the
microprocessor module. This set of parts forms a calibrated pair, so that readout in pico
Farads (pF) is achieved. An optional safety barrier can be included in the electronic
component.
The probe comprises a measurement section and an active shield section that is a fixed
length. The probe is the primary system sensor, and it indicates the electrical capacitance
value of the measurement section relative to the environment (tank wall, stilling well, or
conductive material). This part of the probe connects to the capacitance detector in the
electronic transmitter.
