Reliable level switching in conductive liquids helps protect tanks, pumps and plant processes from avoidable interruptions. KAK detects one or two limit levels in electrically conductive liquids with conductivity from 5 µS/cm or resistance up to 200k Ohm, making it suitable for overflow protection, dry-run protection and two-point control.
The standard version is built for general industrial applications. It supports process temperatures from -40 °C to +100 °C and pressures from -1 bar to +10 bar, with ingress protection (IP65) for control and plant environments. Wetted materials include CrNi steel, Hastelloy C22 and titanium, allowing use with aggressive media where suitable.
Integration is flexible because the KAK is available with universal 20...253VAC/DC supply and relay output, or with 24VDC supply and PNP switching output. Adjustable sensitivity lets the switching response be matched to the conductivity of the liquid.
The switch evaluates electrically conductive liquids in vessels or pipelines. Depending on the measuring system, it detects one or two limit levels with a common reference electrode.
Configurations include 1-rod, 2-rod and 3-rod designs for one limit value or two limit values. Electrode lengths can be specified up to 2500 mm.
Threaded ISO 228-1 process connections are available as G ½" for 1-rod versions, G 1" for 2-rod versions and G 1½" for 3-rod versions.
Electrode rods are available in CrNi steel, Hastelloy C22, titanium or CrNi steel with a 50 mm tantalum tip. KAK electrode insulation is available in PA, ETFE or E-CTFE.
Versions are available with terminal compartment or M12 x 1, A-coded, 4-pin connector for 24 V DC supply.
Connection housings are available in POM, PP, PTFE or CrNi steel, depending on the selected configuration.
