Understanding Toroidal Conductivity Sensors
A toroidal conductivity sensor is a type of conductivity sensor that measures the conductivity of a liquid or chemical using a toroidal (doughnut-shaped) coil. The coil is powered by an alternating current (AC), which produces a magnetic field all around it. The magnetic field changes as a result of the conductivity of the liquid or chemical, and this change can be measured and used to calculate the conductivity.
A toroidal coil serving as the sensor is wrapped around the pipe or tank containing the liquid or chemical being measured. When the coil is linked to an AC power source, an alternating current is produced and passed through the coil. The conductivity of the liquid or chemical affects the magnetic field that is produced by this current around the coil. A sensor, like a Hall effect sensor, that is housed inside the toroidal coil can detect the change in the magnetic field brought on by the conductivity of the liquid or chemical.
The sensor can also be calibrated using a reference solution to give a precise reading of the liquid or chemical’s conductivity.
Toroidal conductivity sensors are superior to other types of conductivity sensors in a number of ways. They are non-invasive since neither they nor any foreign materials are introduced into the liquid or chemical come into touch with the substance. They may be used to detect the conductivity of a variety of liquids or compounds and are also incredibly accurate.
Toroidal conductivity sensors can be used for a variety of tasks, such as testing the cleanliness of liquids or chemicals or checking the conductivity of water. They can also check the strength of chemical solutions. They can be applied in a number of sectors, such as medicines, chemical processing, and water treatment.
While conductivity sensors can be used in a variety of applications, it’s vital to keep in mind that some liquids and chemicals—such as those that are excessively viscous or have a lot of suspended solids—may not be compatible with them. A professional should always be consulted to help you choose the finest sensor for your unique requirements.
