Level Sensor : Continuous Level Sensors for Solids

Capacitive level sensor

Capacitive level sensors CG/CGM (phase detection)

Capacitive level sensors CG/CGM (phase detection)
CE

Overview
Microcomputer (digital circuit) converts change in measured capacitance to change in frequency, and determines resonant frequency. The phase difference is measured to indicate the liquid level.
Features
Zero/span points are automatically calculated. Insensitive to conductive material buildup.
Applications
Liquid level measurementLiquid level measurement

Capacitive level sensors CL (with detector)

Capacitive level sensors CL (with detector)

Overview
The sensor has an electrode suspended with a coaxial cable. The electrode is inside a pipe located in a tank. The change in electrode capacitance is measured to indicate a level. Detector: flameproof (d2G4) Controller: Intrinsic safety (i2G4)
Features
  • Electrode is inside a plastic pipe, and insensitive to buildup, chemicals or gases, realizing stable measurement.
Applications
Level measurement of various liquids and solids, interface measurement of two different liquids
