The Model Q40CT toroidal conductivity system is designed for on line monitoring of chemically aggressive process solutions. This blind, analog version is ideally suited for applications where reliable instrumentation is critical and economy of installation is essential.
Toroidal sensors are available in polypropylene, Kynar 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.
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 materials is either polypropylene or 316 stainless steel. For larger pipe diameters, the sensor can be insertion mounted through a 1 ½" NPT ball valve for easy retraction.
The Q40CT is also available as a Concentration Monitor. The monitor comes with concentration/temperature table 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 Q40CT 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.
Features
Loop Powered Version: Transmitter is powered by 16-35 VDC via a twisted pair, which also carries analog output signal
Selectable Measuring Range: User selects system measuring range to improve resolution of output signal. Measuring range options are minimum 0-1000 microSiemens to a maximum or 0-1,000,000 microSiemens.
Easy Calibration: Easily accessible controls for adjusting system offset and span.
Automatic Temperature Calibration: Temperature response curve is user adjustable ti improve measurement accuracy.
NEMA 4X Enclosure: Polycarbonate enclosure is weather proof and corrosion resistant to protect electronics from environmental influence.
Multiple Monitoring Configuration: Universal mounting bracket allows for wall, pipe, DIN rail, handrail and panel mounting options.
