Minicap FTC260, FTC262

Endress+Hauser

Function Range

There is a loose relationship between the dielectric constant εr and the density ρ of the material.

The table on the left indicates whether the Minicap can be used or if application limits are exceeded.

In general:

If the dielectric constant of the process medium is not known, then the bulk density can be a deciding

factor.

Experience shows that the Minicap functions in foodstuffs with a density of 250 g/l and above or

in plastic or mineral materials with a density of 600 g/l and above.

Setting the Sensitivity

The Minicap is so calibrated at the factory that it correctly switches in most materials.

Greater sensitivity can be set using a switch on the electronic insert. This is necessary if there is very

strong build-up on the probe, or if the dielectric constant εr of the material is very small.
