ACS Conductivity Sensor

The ACS Conductivity Sensor, manufactured and supplied by Aranka Instruments LLP, a leading ACS Conductivity Sensor manufacturer and supplier in Ahmedabad, Gujarat, India, is designed for accurate measurement of a solution’s electrical conductivity. Its working principle is based on detecting the ability of a liquid to conduct electric current, which reflects its ionic concentration and overall purity. Built with high-quality electrodes and temperature-compensated design, the sensor ensures precise and stable readings in varied process conditions. Ideal for water treatment, chemical, pharmaceutical, and food & beverage industries, the ACS Conductivity Sensor offers long-term reliability, corrosion resistance, and smooth integration with Aranka’s range of conductivity controllers for effective monitoring and process automation.

working principle:

  1. 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.
  2. Electrical Potential: An electrical potential (voltage) is applied across the electrodes. This creates an electric field in the solution between the electrodes.
  3. 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.
  4. 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.
  5. 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).
  6. 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.

Frequently Asked Questions (FAQs)

What is a conductivity sensor?

A conductivity sensor measures the electrical conductivity of a solution, which indicates how well the solution conducts electric current. It does so by applying a voltage across electrodes and measuring the resulting current—higher ionic concentration leads to higher conductivity.

Why is temperature compensation needed?

Conductivity changes with temperature (ions move more at higher temperatures). A good sensor includes temperature compensation to correct readings to a standard reference temperature so that variations don’t distort measurements.

What materials are used for the sensor and isolation?

  • Sensor body / electrodes: Stainless Steel 316 (SS316)
