NVS-345
NVS-345
Conductive Multilevel Sensor
Application/intended use
Point level measurement in aqueous, conductive media in tanks and pipes with minimum conductivity.
The conductivity depends on the evaluation device: 1 μS/cm when using external evaluation units, e.g. VNV series or ZNV-Z, and 10 μS/cm when using the internal level transmitter MNV-1C.

Selection of the right sensor type
Coating: For foamy, adhesive (e.g. yogurt) and/or wetting media (e.g. alkaline solutions), we suggest using a sensor with a coated electrode. Sensors with an uncoated electrode are recommended for aqueous, non-adhesive and non-wetting media. If rod lengths are greater than 500 mm, the coated version should be used since the electrodes may come into contact with each other and lead to incorrect readings.
