3. Description.
3.1 Product overview
Inductive method :
A ring-type coil is excited at fixed intervals and the response is retrieved on a second coil, which is
linked to the excited coil. The connectivity between the coils (determined by the degree of conductivity)
takes place via the conducting solution.
Economic and successful technology that requiring not enough maintenance and not consumable.
The CTZN sensor offers the following advantages:
• Low operating costs due to reduced maintenance work (no electrolyte changes)
• Greater calibration intervals due to low drift behaviour
• No polarization voltage required • High measuring accuracy, even for low concentrations • Rapid
response times
The sensor features excellent interference immunity thanks to the integrated preamplifier and digital
signal processing. The measured value for conductivity is automatically compensated with the
temperature and transferred without interference to the connected display unit and controller via a
digital interface. The sensor also includes a log book containing the last ten successful calibrations in
the form of a ring buffer.
3.2 Applications
The compact and robust sensor is particularly well suited to the following typical areas of application:
• Urban wastewater treatment
• Industrial effluent treatment
• Surface water monitoring
• Sea water
• Fish farming
