kotron ? tip sensitive rf level sensor description kotron tip sensitive level controls can be utilized in liquid or bulk material applications. there are no moving parts in contact with the medium. these units are integral systems with the sensing probe mounted with the electronics. features integral nema 4x/7/9 aluminum enclosures ? robe length can be field modified from 14" (356 mm) standard length to a minimum of 4" (100 mm) 316 stainless steel probe maximum pressure up to 3000 psig @ +100 f (205 bar @ +40 c) dielectric constant as low as 2.0 ? amp spst relay field selectable fail-safe jumper wire application economical solution for integral point sensor in: liquids slurries ?ry bulk material technology as material covers the probe, there is a change in the dielectric of the material surrounding the probe. this creates an increase in capacitance which is detected by the electronics and converted into a relay activation. when the probe is uncovered, the capacitance is reduced and the relay is reset.
