Conductivity sensors are pre-destined for use in the food industry. They detect the conductivity and concentration of different media and can differentiate between e.g. cleaning agents, rinsing water, and the food product. This means that it is not only possible to constantly track the product but also to reduce the waste of product and rinsing water – all possible without making adjustments to the sensor. Oil sensors monitor the quality of hydraulic fluids and lubrication oils. To be more precise the particle monitor type LDP detects the purity level / level of contamination of mineral-, ester- and bio-oils. The oil humidity sensor type LDH measures the relative humidity and concentration of water in oil.
Analytical sensors make an important contribution to condition-based monitoring and the avoidance of downtime. Conductivity sensors are pre-destined for use in the food industry. They detect the conductivity and concentration of different media and can differentiate between e.g. cleaning agents, rinsing water, and the food product. A conductivity sensor measures the ability of a solution to conduct an electrical current. It is the presence of ions in a solution that allow the solution to be conductive: the greater the concentration of ions, the greater the conductivity.
Conductivity is used to monitor both the concentration of the CIP solution, typically sodium hydroxide, and the completeness of the rinse. Interface detection. If two liquids have appreciably different conductivity, a conductivity sensor can detect the interface between them. The unit of electrical conductivity is, by definition, the reciprocal of electrical resistivity, S/m (siemens per meter) in SI units.
