Level Switches

Our thermal dispersion level switches are are both ATEX Exd certified and SIL2 rated.

Thermal dispersion technology measures the temperature difference between an active (heated) RTD and a reference (un heated) RTD. This is greatest in a dry condition and decreases rapidly when wet, cooling the heated RTD.
