Alarm thresholdas per USPPreliminary alarm thresholdUltrapure water 123 0507510025 Conductivity [S/cm] Temperature [հC] In the pharmaceutical industry, particu-larly high demands are made regarding the hygiene and cleanability of the plant units. The most important raw material is ultrapure water. It is a solvent for a wide range of substances which are introduced or injected and it is used to clean or rinse plants before the next production batch.The United States Pharmacopeia (USP) standard is the standard that is accepted worldwide for the purity of water. The re- quirements for water...

The measurement of electrolytic conductivity in liquids directly in the process has been applied for many years in the process-engineering industry for control and monitoring purposes. Since all the ionic parts of acids, alkalis and salts contribute to the conductivity, this is a very multi-faceted measurement method for deter- mining the concentration of chemical solutions or the purity of water.Electrolytic conductivity in liquids arises from the fact that acids, alkalis and water-soluble salts dissociate into positively charged cations and negatively charged ani- ons. Just like electrons...

Advantages of conductive sensors: > Working principle: The choice of sensor with a certain cell constant is based on the desired measur- ing range: the lower the conductivity, the smaller the cell constant selected. The size of the cell constant has an influence on the optimum arrangement of the electrodes. For ultrapure water, a concentric arrangement of the cylindrical electrodes is preferred. The electrical conductivity of liquids is de-termined with a measuring arrangement in which two electrodes are located opposite one another as is the case with a capacitor.According to Ohm's Law,...

Working principle: 4312 In inductive conductivity measurement, a transmitter coil (1) creates a magnetic alternating field which induces an electric voltage in the medium. This causes the positively or negatively charged ions in the fluid to be set in motion and an electric alternating current flows in the liquid (2).This current generates a magnetic alter-nating field in the receiving coil (3). This causes an induction current in the coil which is evaluated by the electronics (4). The conductivity is then determined from this. Advantages of inductive sensors: No restrictions for high...
