How Do Toroidal Conductivity Sensors Work?

A toroidal conductivity sensor is a type of conductivity sensor that works by using a toroidal (doughnut-shaped) coil to measure the conductivity of a liquid or chemical. It works by passing an alternating current (AC) through the coil, which creates a magnetic field around the coil. The conductivity of the liquid or chemical causes a change in the magnetic field, which can be measured and used to determine the conductivity.

The sensor consists of a toroidal coil that is placed around the pipe or tank containing the liquid or chemical to be measured. The coil is connected to an AC power source, which generates an alternating current through the coil. This current creates a magnetic field around the coil, which is influenced by the conductivity of the liquid or chemical. The conductivity of the liquid or chemical causes a change in the magnetic field, which can be measured by a sensor, such as a Hall effect sensor, which is located inside the toroidal coil.

The sensor can also be calibrated with a standard solution to provide a direct reading of the conductivity of the liquid or chemical.

Toroidal conductivity sensors have several advantages over other types of conductivity sensors. They are non-invasive, which means that they do not come into contact with the liquid or chemical, and they do not introduce any foreign materials into the liquid or chemical. They are also highly accurate and can be used to measure the conductivity of a wide range of liquids or chemicals.

Toroidal conductivity sensors are suitable for use in a wide range of applications, including monitoring the conductivity of water, monitoring the strength of chemical solutions, and measuring the purity of liquids or chemicals. They can be used in a variety of industries, including water treatment, chemical processing, and pharmaceuticals.

l It’s important to note that while conductivity sensors are suitable for use in a wide range of applications, they may not be suitable for use with certain types of liquids or chemicals, such as those that are highly viscous or have high levels of suspended solids. It’s always important to consult with an expert to determine the best sensor for your specific needs.
