Conductive level switch EL22

for liquidspolypropyleneprecision

Kari-Finn offers sensors of extremely high level of precision for the monitoring and control of conductive liquids. From our selection, you can find an ideal solution for a wide range of applications, from indoor premises to wells and containers. Their central unit, the KARI EL22 electrode switch, renders our sensors suitable for a variety of uses. In addition to serving as a high- and low-level alarm system, they can be used to determine the desired start and stop levels KARI EL22 electrode switch, a central unit for sensors Approved by the SGS Fimko certification body, our sensors’ central unit, the KARI EL22, is an extremely accurate monitoring and control device, which enables the determination of the sensor’s operational levels with a precision of less than a centimetre. The system can be adjusted in line with a liquid’s conductivity The system is suitable for use in a wide range of conditions, as its sensitivity can be adjusted in accordance with the liquid’s conductivity. The KARI EL22 lends itself to a variety of applications, depending on the choice of sensors. It can be used to: prevent the dry-running of deep-well pumps control charging and discharging control motor and magnetic valves give high- and low-level alarms determine doses act as a flooding sensor for indoor premises Safe and robust Measurements are performed safely with extra low voltage (SELV or PELV). The KARI EL22 is separated from the input current by a double-insulated transformer that is protected against short-circuiting, with an additional safety precaution provided by a casesolution that is safe even in the event of a lead coming loose. Each KARI EL22 central unit undergoes functionality
