Innovative Sensor Technology (IST) has used thin-film technology to develop a conductivity sensor for measuring the concentration of ions in an electrolyte, ideal for use in determining water quality.

By measuring the voltage drop between two current electrodes, the conductivity of a substance can be determined.

The operating temperature range of the sensor is 0C to +90C and its measurement range is ~5mS/cm to ~20mS/cm.

The conductivity sensor consists of two current electrodes, two measuring electrodes and a platinum temperature sensor for compensation.

The sensor has an integrated Class B 100ohm or 1,000ohm temperature sensor.

Since the conductivity of an electrolyte depends on the temperature of the medium, it is important to have accurate temperature compensation, according to the company.

The platinum RTD is located on the sensor, directly at the point of measurement to ensure accuracy.

Conductivity sensors can be used to determine water quality, measuring the concentration of ions found in the water.

IST’s conductivity sensor is ideal for this application as well as others to measure the conductivity of an electrolyte.

The sensors are able to measure the conductivity of most electrolytes, excluding those that are volatile to platinum.
