The CDTX-45T toroidal conductivity system is designed 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 sensor is available in Noryl
to ensure that sensor-wetted materials are chemically resistant to process
chemicals. The sensor material is non-conductive, 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.
Sensor can be submersion mounted for easy installation in
open tanks or pipe mounted in the optional 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 1 1/2 NPT ball
valve for easy retraction.
