Protocol
The CDCN442 toroidal conductivity system
isdesigned for online monitoring of chemically
aggressive process solutions, water applications
that coat or foul traditional sensors, and plating
bath operations in which high current densities are
present. The sensor consists of 2 metallic ribbon
coils that are fixed in place by the sensor jacket
material. The drive coil is used to induce a current in
the process solution. The second sensing coil is used
to measure the current in the process solution; the magnitude
of this current is proportional to the conductivity of the process
solution. Toroidal sensors are available in polypropylene, and
PEEK
TM
to ensure that sensor-wetted materials are chemically
resistant to process chemicals. The sensor material is nonconductive, thereby isolating the sensor from electrical noise and
ground loops that can influence the integrity of the measurement.
This material also makes the sensor resistant to electrode coating,
since most substances do not adhere to the sensor material.
Sensors can be submersion mounted for easy installation in open
tanks or pipe mounted in the optional 51 mm (2") tee fitting, which
is keyed to the sensor for proper alignment. Tee fitting material is
polypropylene. For larger pipe diameters, the sensor can be
insertion mounted through a 11⁄2 NPT ball valve for easy retraction.
The monitor comes with concentration/temperature tables for
sodium hydroxide, potassium hydroxide, hydrochloric acid, nitric
acid, and sulfuric acid. A configurable table allows the user to enter
data points for a custom concentration curve. Typical
applications include waste water treatment, power plants,
thermo electric plants, pharmaceutical, photographic industries,
soft drinks industries.
