The LC300 is a 2-wire-loop-powered capacitance level probe transmitter for level measurement of liquids, solids and slurries.
- High sensitivity
- 2-wire design
- Push-button calibration
- Easy installation & maintenance
Available in two versions (rod and cable), the SITRANS LC 300 capacitance level probe 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.
The LC300 capacitance level probe 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 level measurement instrument combining a sophisticated, yet easy-to-adjust, microprocessor with field-proven Pointek CLS 300 probes. It is available in two versions: rod and cable.
All wetted parts are made of stainless steel with a PTFE/FEP insulator for high chemical resistance. Materials with low or high dielectric properties are accurately measured and the patented Active-Shield technology helps in ignoring the effects of build-up.
- Patented Active-Shield technology
- High-sensitivity probe
- Fast, cost-effective set-up using LCD
- 2-wire (4-20 mA) current loop design
- Current signalling according to NAMUR NE 43
- Push-button calibration
- Easy to install and maintain
- 'Levelwatch' network friendly for Internet-based remote monitoring
