Q40CT Blind Toroidal Conductivity Transmitter
Blind Transmitter for OEM Applications
- General Details
The 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. For larger pipe diameters, the sensor can be insertion mounted through a 1-1/2″ NPT ball valve for easy retraction.
The Q40CT toroidal conductivity water quality monitor is easy to operate, requires minimal maintenance and is economical to own, yet provides reliable measurement of your chemical process.
Concentration version for direct display of chemical concentrations.
Expansion board to add a third 4-20 mA analog output or to add three additional non-isolated low power relays.
Wide range capability, with selectable ranges of 0-200.0 uS up to 0-2.000 S provide maximum application flexibility.
