Capacitive Sensors

Monitoring liquid levels and detecting various materials in a tank is easiest with a capacitive sensor.

• BCC series is excellent for solid materials.
  It detects powders and granules even through thick plastic walls and is protected against static electricity.
• BFC series works perfectly when there are liquid residues on tank walls. 
  This sensor can compensate for liquid adhering to the walls and only detects when the level is actually at the sensor's position.
• BCT series with IO-Link output for detecting dielectric constants in materials.
• QF5.5 sensor is very small, and its installation options are nearly limitless. 
  For example, it can be mounted to a pipe using cable ties or screwed onto a plastic tank wall. Despite its small size, the detection range is 10 mm.
