What does a conductivity sensor do?
Conductivity is the measurement of the solution or substance’s ability to carry or conduct an electric current. Conductivity sensors are used to measure conductivity in aqueous solutions to determine the purity or impurity of a liquid.
What is an inductive conductivity sensor?
Inductive Conductivity Inductive sensors are using two electromagnetic coils usually encased in a polymer ring. An alternating voltage is applied to the driving coil, which induces a voltage in the receiving coil. The induced current is influenced by the conductance of the solution.
What is the output of conductivity sensor?
Available conductivity ranges are 0-200µS/cm, 200-2000µS/cm, 2-20mS/cm, 20-200mS/cm and 200-2000mS/cm. The conductivity sensor’s temperature output has a measurement range of -5°C to +70°C.
How many types of electrode sensor techniques can be used to measure conductivity?
There are three main technologies used to measure liquid conductivity. Selecting the proper sensor technology is dependent upon the type of application and the expected conductivity measurement range.
What is the principle of conductivity meter?
The principle by which instruments measure conductivity is simple—two plates are placed in the sample, a potential is applied across the plates (normally a sine wave voltage), and the current that passes through the solution is measured….Conductivity.
| Cell Constant(K) | Optimum Conductivity Range (µS/cm) |
|---|---|
| 10.0 | 1000 to 200,000 |
What is conductivity sensor for water?
Water conductivity sensors are used in water-quality applications to measure how well a solution conducts an electrical current. This type of measurement assesses the concentration of ions in the solution. The more ions that are in the solution, the higher the conductivity.
What is the principle of conductivity?
Conductivity is the ability of a material to conduct electric current. The principle by which instruments measure conductivity is simple—two plates are placed in the sample, a potential is applied across the plates (normally a sine wave voltage), and the current that passes through the solution is measured.
What is the unit of conductivity?
Siemens per meter
Conductivity (or specific conductance) of an electrolyte solution is a measure of its ability to conduct electricity. The SI unit of conductivity is Siemens per meter (S/m).
What is conductivity unit?

What are the 2 types of conductivity?
What Are Different Types of Conductivity?
- Thermal conductivity – thermal conductivity is a material’s ability to conduct heat or thermal energy.
- Electrical conductivity – metallic and polarised materials are good electrical conductors.
What is PPT in conductivity meter?
TDS (Total Dissolved Solids) and Conductivity Measurements Use the MODE button to switch between the TDS and the Conductivity measurement modes. In TDS mode the unit of measure is ppt (parts per thousand) or ppm (parts per million). In Conductivity mode the units of measure are µS or mS (micro- or milli-Siemens).
