Table of Common Dielectric Constants
NOTE: Liquids with a dielectric constant less than 20 will not be detected by an LP15 or LP10 series level switch, as factory calibrated.
Note: The TFA Teflon sensors are designed so the sensing tips can be submersed in the process liquid, but
the cable must not be submersed.
