Conductivity Sensor Suppliers

A conductivity sensor is an electronic device that measures the ability of a solution to conduct electricity. It works by passing a small electric current through the solution and measuring the resulting voltage. The conductivity of the solution is directly proportional to the current flow and inversely proportional to the resistance of the solution. The sensor typically consists of two electrodes, one that is charged with a voltage and the other that measures the resulting current flow. The conductivity of the solution can be used to determine the concentration of dissolved ions or the purity of the solution. Conductivity sensors are commonly used in water treatment, chemical processing, and food and beverage industries.

There are various types of conductivity sensors available in Australia, including:

• Contacting conductivity sensors: These sensors use two electrodes to measure the conductivity of a solution. They are commonly used in industrial applications.
• Inductive conductivity sensors: These sensors use a coil to measure the conductivity of a solution. They are non-contacting and are commonly used in the food and beverage industry.
• Toroidal conductivity sensors: These sensors use a toroidal coil to measure the conductivity of a solution. They are non-contacting and are commonly used in the pharmaceutical industry.
• Optical conductivity sensors: These sensors use light to measure the conductivity of a solution. They are non-contacting and are commonly used in the biotechnology industry.

Four-electrode conductivity sensors: These sensors use four electrodes to measure the conductivity of a solution. They are commonly used in research and development applications.

However, the range of conductivity measurement for a typical sensor can vary depending on the application and the type of sensor. Some sensors have a range of 0-2000 μS/cm, while others can measure up to 20,000 μS/cm or more. It is important to choose a sensor with a range appropriate for the specific application to ensure accurate measurements.

The accuracy of a conductivity sensor can be affected by several factors, including temperature, electrode condition, sample composition, and calibration. Temperature can affect the conductivity of the sample, and therefore, the readings of the sensor. Electrode condition, such as fouling or damage, can also affect the accuracy of the sensor. Sample composition, such as the presence of impurities or dissolved solids, can also impact the conductivity readings. Finally, calibration is critical to ensuring accurate readings, and factors such as the calibration solution and frequency of calibration can affect the accuracy of the sensor.

Choosing the right conductivity sensor for your application involves considering factors such as the type of solution being measured, the conductivity range, the accuracy and resolution required, the temperature range, the chemical compatibility of the sensor material, and the installation method. It is important to consult with a knowledgeable supplier or manufacturer to ensure that the sensor selected is appropriate for the specific application.

A conductivity sensor requires periodic cleaning to remove any buildup of contaminants on the sensor surface. The frequency of cleaning depends on the application and the level of contamination. The sensor should also be calibrated regularly to ensure accurate readings. The calibration frequency depends on the application and the level of accuracy required. The sensor should be stored properly when not in use to prevent damage or contamination. Additionally, the sensor should be inspected regularly for any signs of physical damage or wear and tear.

It depends on the specific conductivity sensor and the harsh environment in question. Some conductivity sensors are designed to withstand extreme temperatures, pressure, and chemical exposure, making them suitable for use in harsh environments such as industrial processes, wastewater treatment plants, and oil and gas production facilities. However, other conductivity sensors may not be able to withstand these conditions and may require additional protection or maintenance to function properly. It is important to carefully evaluate the specifications and capabilities of a conductivity sensor before using it in a harsh environment.

The cost of a conductivity sensor in Australia may vary depending on the brand, model, and supplier. It is best to check with local suppliers or online stores to get an accurate price range.

Yes, most conductivity sensors come with warranties or guarantees. The length and terms of the warranty or guarantee may vary depending on the manufacturer and the specific product. It is important to check the warranty or guarantee information before purchasing a conductivity sensor to ensure that it meets your needs and expectations.
