Proven level detection

Conductive probes EL

Flexible determination of the switching point

Measuring principle and applicationsThe instruments work according to the conductive measuring principleand are used in conductive liquids. The probe detects the productresistance when being immersed. A low alternating current flows whichis detected by the integrated electronics and converted into a respectiveswitching signal. The switching signal is determined via the mountingposition or the length of the respective probe. The easy and robustconstruction of the sensors offers a maintenance free and reliable leveldetection in all areas of industrial measurement technique. Typicalapplications are e.g. overfill protection, pump control or dry runprotection.
