KROHNE OPTISYS IND 8100 hygienic inductive conductivity measuring system

KROHNE has introduced the OPTISYS IND 8100 hygienic inductive conductivity measuring system for the food and beverage industry. It is suitable for applications in the field of product separation/identification or in CIP plants to shorten transition phases and save cleaning fluids.

The 3A and EHEDG certified measuring system offers two 4-20 mA outputs for conductivity, concentration and temperature. Within the conductivity measuring range from 50 μS/cm to 1000 mS/cm, the system features 14 preset range/output combinations. Alternatively, the analog output can be set.

For media separation, four conductivity ranges can be defined. The concentration output can be used to display the concentration of four factory-set mediums/ranges, such as caustic soda, nitric acid or a customer-set medium, where the concentration curve can be programmed via a 30-point linearisation. The short response time of the integrated Pt100 temperature sensor (T90<15 s) allows for fast indication of changes in medium or process conditions. The corresponding conductivity is also indicated (T90<2 s) for fast identification of CIP reagents to prevent blending and save costs.

The system features different selectable display modes and warnings. There are two solid-state relay contacts configurable as limit switches.

The compact design with IP67/69K housing is suitable for pipes with small diameters >DN40/1½″. The sensor is encapsulated in a PEEK body for use in hygienic processes or direct in concentrated acids or alkalis. Various hygienic process adapters such as Tri Clamp, DIN 11851, SMS or Varivent N are available.
