Inductive conductivity / concentration transmitter INDUTEC

Inductive conductivity/concentration transmitter INDUTEC


  • hygienic sensor
  • activation of up to four measuring ranges and temperature coefficients
  • concentration measurement of caustic soda naoh and nitric acid HNO3
  • fast-response temperature sensor- linear, natural water or specific characteristic


The instrument is used for the measurement/control of conductivity or concentration in liquid media. It is particularly recommended for use in media where severe deposits of dirt, oil, grease or gypsum/lime precipitates are to be expected. The integrated temperature measurement enables fast and accurate temperature compensation, which is of particular importance when measuring conductivity. Additional functions, such as the combined changeover of measurement range and temperature coefficient, and a particularly robust conductivity probe, enable optimum application in CIP processes.

Two built-in switching outputs can be freely programmed to monitor limits for conductivity/concentration and/or temperature. It is also possible to assign alarm and control functions (dilution).

The instrument is operated from the membrane keypad and plain-text graphics display. The display can be read in a vertical or horizontal mounting position. Temperature signal 4...20mA is available as second parameter.

Typical areas of application: Food/beverage and pharmaceutical industries, product separation in the beverage industry, breweries and dairies, bottle cleaning plant, concentration control in electroplating and chemical processing plant, CIP systems, water and wastewater engineering, dosing of chemicals, leakage indication, in heating and cooling plant, and so on.

The inductive measurement method permits largely maintenance-free acquisition of the specific conductivity, even in the toughest media conditions.

Conductivity is measured by using an inductive probe. A sinusoidal a.c. voltage feeds the transmitting coil. Depending on the conductivity of the liquid to be measured, a current is induced in the receiver coil. This current is proportional to the conductivity of the medium.
