ATI - Model Q45CT - Toroidal Conductivity Monitor
From Water Monitors
ATI’s Model Q45CT Toroidal Conductivity system is designed for online monitoring of chemically aggressive process solutions. This sensor consists of two 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 to ensure sensor wetted materials are chemically resistant to process chemicals. Sensor material is also 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, as 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 2' tee fitting, which is keyed to the sensor for proper alignment. Tee fitting material is either polypropylene or 316 stainless steel.
The Q45CT is also available as a Concentration Monitor. The monitor comes with concentration/temperature tables for sodium hydroxide, potassium hydroxide, hydrochloric acid, nitric acid, and sulfuric acid. A user configurable table is also available for entering data points for a custom concentration curve.
The ATI Model Q45CT toroidal conductivity system is well suited for aggressive chemical processes, water application that coat or foul traditional sensors, and plating bath operations where high current densities are present. The toroidal sensor is also referred to as an electrodeless conductivity sensor, or a 0E conductivity sensor.
