Application in Different Industries
Conductivity sensors and transmitters find applications in a multitude of industries such as food & beverage, chemicals, life sciences, pharmaceuticals, water treatment, and power generation. The selection of sensors depends on the specific application and the range of conductivity required. For low conductivities in pure and ultrapure water, conductive sensors are preferred, while toroidal sensors are ideal for media with high conductivity levels. 4-electrode sensors are utilized in scenarios where a wide measuring range is necessary, such as phase separation processes.
Measurement Principles
Conductivity measurements can be carried out using conductive sensors, conductive 4-electrode sensors, or toroidal sensors. Conductive probes operate by applying an alternating voltage between two electrodes to measure the current generated by the movement of free ions in the liquid. The conductivity value is determined by the current flow, with the unit being Siemens per meter.
Calibration and Standards
Endress+Hauser offers comprehensive conductivity calibration solutions and standards to ensure precise measurements. The exact cell constant of the conductivity sensors is factory-measured and certified, contributing to the reliability of the results. The product range includes compact devices combining a conductivity sensor with a transmitter, making them particularly well-suited for the stringent requirements of the food & beverage industry.
