Thank you for choosing a NIVELCO instrument We are sure that you will be satisfied throughout its use 1 APPLICATION The conductive measuring principle can be applied to liquids with specific conductivity over 10 uS cm The switching unit can sense the resistance between probes Conductivity measurement is suitable only for detecting the presence of liquid at a given level of the tank This level is represented by the length of the probe The level switch consists of a NIVOCONT KRK 512 1 type switching unit and the KLN 2010 type probes selected according to the task Probes are to be connected to the NIVOCONT KSL1 20 type probe socket head that can be screwed into the tank If the material of the tank or its internal insulation is not conductive then a reference probe should be used in addition to the one two three or four probe s if the material of the tank is conductive the tank can be used as a reference probe The conductive switch is suitable for filling emptying control or level limit 2 TECHNICAL DATA 2 1 GENERAL DATA 2 1 1 TECHNICAL DATA OF THE SWITCHING UNIT KRK 512 0 5 VAC lt 0 5mA AC Adjustable 5 kQ 100 KQ 3 nF max 400 ms 5 Adjustable 0 5 10 s 1x SPDT 250 V AC1 24 VDC 16 A AC1 4000 VA AC1 384 W DC 4kV Type Probe voltage Probe current Sensitivity Max cable capacity Response Setting accuracy mech Delay Relay output Switching voltage Switching current Switching power Electrical stren
