Application
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.

Measuring principle
Point Level Detection
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.
Active Build-up Compensation
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.
Measuring System
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.)
