High Conductivity Sensors ISC40/SC42

Description:

There are two basic sensor styles used for measuring Conductivity: Contacting and Inductive (Toroidal, Electrodeless). When Contacting Sensors are used, the conductivity is measured by applying an alternating electrical current to the sensor electrodes (that together make up the cell constant) immersed in a solution and measuring the resulting voltage. The solution acts as the electrical conductor between the sensor electrodes. With Inductive Conductivity (also called Toroidal or Electrodeless), the sensing elements (electrode coils) of an inductive sensor do not come in direct contact with the process. These two matched (identical) coils are encapsulated in PEEK (or Teflon) protecting them from the adverse effects of the process. There is only one cell factor (constant) for the ISC40 Inductive Sensor. It covers nearly the entire conductivity measurement range ~ 50-2,000,000 µS/cm. Only on the low end (below 50 µS) does the accuracy of the sensor suffer. Because the ISC40 Inductive sensor is virtually maintenance free; it is the first choice for any application. If the ISC40 cannot be used then it is recommended to use the 4-electrode design, model SC42 large bore sensor. ……

High Conductivity Sensors ISC40/SC42

There are two basic sensor styles used for measuring Conductivity: Contacting and Inductive (Toroidal, Electrodeless).

When Contacting Sensors are used, the conductivity is measured by applying an alternating electrical current to the sensor electrodes (that together make up the cell constant) immersed in a solution and measuring the resulting voltage. The solution acts as the electrical conductor between the sensor electrodes.

With Inductive Conductivity (also called Toroidal or Electrodeless), the sensing elements (electrode coils) of an inductive sensor do not come in direct contact with the process. These two matched (identical) coils are encapsulated in PEEK (or Teflon) protecting them from the adverse effects of the process.

There is only one cell factor (constant) for the ISC40 Inductive Sensor. It covers nearly the entire conductivity measurement range ~ 50-2,000,000 µS/cm. Only on the low end (below 50 µS) does the accuracy of the sensor suffer.

Because the ISC40 Inductive sensor is virtually maintenance free; it is the first choice for any application. If the ISC40 cannot be used then it is recommended to use the 4-electrode design, model SC42 large bore sensor.
