Innovative Sensor Technology IST AG has combined thin- and thick-film technologies to develop ceramic-based conductivity sensors that include a resistive temperature sensor (Pt1000 IEC 60751 F0.3), thus allowing for accurate compensation at the point of measurement. Conductivity measurements are widely used in industrial and environmental applications as a simple and inexpensive way to control the ionic content in a solution. In water purification systems, the conductivity is monitored at different stages of the process. Since the mobility of the dissolved ions is affected by temperature, these monitoring systems are required to either control the process temperature or to compensate readings according to the sample temperature.
