Capacitance Level Transmitters
GENERAL FEATURES
DOWNLOAD PDF
- Measures level using changes in electrical capacitance
- Works by detecting capacitance variation between probe and vessel wall (or reference electrode)
- Capacitance changes as level varies due to dielectric differences
- Converts capacitance variation into accurate level signal output
- Suitable for both conductive and non-conductive liquids
- Applicable for slurries and granular solid materials
- Can be used for interface level measurement
- Reliable performance across a wide range of industrial applications
