ENDRESS+HAUSER  FTC260-AA2B1

The Minicap is designed for point level detection in light bulk solids with a grain size up to max. 30 mm (1.18 in) and a dielectric constant Et>1.6 e.g. grain products, flour, milk powder, animal feed, cement, chalk or gypsum.

• Complete unit consisting of the probe and electronic insert:
  • simple mounting
  • no calibration on start-up
• Active build-up compensation
  • accurate switch point
  • high operational safety
• Mechanically rugged
  • no wearing parts
  • long operating life
  • no maintenance
• The rope probe of the Minicap FTC262 can be shortened
  • optimum matching to the measuring point
  • less stocks required

A metal plate at the end of the probe, within the insulation, the integrated counter-electrode and the surroundings combine to form the two electrodes of a capacitor. If the probe is covered or free of process medium, the capacitance changes and the Minicap switches.

The Minicap detects build-up on the probe and compensates for its effects so that the switch point is always observed. The effects of build-up compensation depend on:

• the thickness of the buildup on the probe,
• the conductivity of the buildup,
• the sensitivity setting on the electronic insert.

Minicap is an electronic switch. The complete measuring system consists of:

• the Minicap FTC260 or FTC262
• a power supply and
• controllers, switching devices, signal transmitters (e.g. lamps, horns, PCS, PLC, etc.)
