MS03 Conductivity Sensor Cube

Brand: Burkert Fluid Control Systems
Does not ship to Virginia, United States

The device is a conductivity measurement sensor. It is used within the Online Analysis System Type 8905 by being plugged into a spare fluidic backplane slot. 

The conductivity of water follows in general the content of dissolved substances in the water. Not only the absolute value at each moment is an indicator for the continuity of the water quality, but quick changes in the conductivity may indicate unwanted change in the water. 

A rising or falling value can also be used as an indicator for process feedback in specific treatment steps. The device contains a 2-electrode sensor for resistive measurement of conductivity. The electrical and fluidic connections are made via the connection panel of the system. 

The sensor cube is communicating via buS, so the recognition at the Online Analysis System is fully automatic. When plugging into a system you will find the sensor in the list of buS members for further customized adjustments.
