Q40CT Blind Toroidal Conductivity Transmitter
Brand: Analytical Technology IncATi’s Blind Toroidal Conductivity analog system is ideally suited for applications where reliable instrumentation is critical and economy of installation is essential.
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 Noryl 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.
