ACS Conductivity Sensor
The working principle of a conductivity sensor is based on the electrical conductivity of a solution, which is a measure of its ability to conduct an electric current. Here’s a simplified explanation of the working principle:
- Electrodes: A typical conductivity sensor consists of two or more electrodes made of conductive materials. These electrodes are usually placed at a fixed distance from each other.
- Electrical Potential: An electrical potential (voltage) is applied across the electrodes. This creates an electric field in the solution between the electrodes.
- Ion Movement: In a solution, various ions (charged particles) may be present, contributing to the conductivity of the solution. These ions can be positively charged (cations) or negatively charged (anions). When the electrical potential is applied, these ions start to move towards the oppositely charged electrode.
- Current Flow: As ions move through the solution towards the electrodes, they carry an electric current. The higher the concentration of ions in the solution, the greater the current flow, and consequently, the higher the conductivity.
- Measurement: The sensor measures the current flowing between the electrodes. The conductivity of the solution is then calculated using Ohm’s Law (I = V/R), where I is the current, V is the voltage, and R is the electrical resistance. Conductivity (σ) is often expressed in Siemens per meter (S/m) or microsiemens per centimeter (μS/cm).
- Temperature Compensation: Since conductivity is also temperature-dependent, many conductivity sensors include temperature compensation mechanisms. This ensures that variations in temperature do not significantly affect the accuracy of the conductivity measurement.
