SE656 Toroidal Conductivity Sensor | Fixed cable | Ex | PFA | Resistant to highly oxidizing media
Description
Special and precise sensor with high chemical resistance over a very large measuring range, for heavily polluted and strongly oxidizing media
- Measurement in hazardous locations
- Robust design
- Extremely large measuring range due to inductive measuring principle
- Insensitive to contamination
- No process-wetted electrodes
- Extremely high chemical resistance (PFA)
Corrosion-resistant toroidal sensor for measuring pure water up to maximum conductivities. Insensitive to strongly oxidizing media. Smooth, easy-to-clean design. High accuracy due to electrodeless measurement. Low risk of contamination because of large sensor opening.
Applications
Conductivity measurement of highly concentrated acid and alkaline solutions, hydrofluoric acid, nitric acid, concentrated sulfuric acid, oleum, concentrated alkaline solutions, strongly oxidizing media
