Inductive conductivity / concentration transmitter INDUTEC
The instrument serves for the measurement and control of conductivity or concentration in liquid media, recommended for use in environments prone to severe deposits of dirt, oil, grease, or gypsum/lime precipitates. Integrated temperature measurement ensures fast and accurate temperature compensation, crucial for conductivity measurements.
Additional functions, including combined changeover of measurement range and temperature coefficient, and a robust conductivity probe, make it ideal for CIP processes.
Two built-in switching outputs can be programmed to monitor limits for conductivity, concentration, and/or temperature, with the option for assigning alarm and control functions (dilution). Operated from a membrane keypad and plain-text graphics display, the instrument is versatile with vertical or horizontal mounting. Temperature signal 4...20mA is available as the second parameter.
Features:
- Hygienic sensor for accurate measurements
- 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
Typical Areas of Application:
- Food/beverage and pharmaceutical industries
- Product separation in the beverage industry
- Breweries and dairies
- Bottle cleaning plants
- Concentration control in electroplating and chemical processing plants
- CIP systems
- Water and wastewater engineering
- Dosing of chemicals
- Leakage indication
- Heating and cooling plants
The inductive measurement method allows largely maintenance-free acquisition of specific conductivity, even in the toughest media conditions. Conductivity is measured using an inductive probe. A sinusoidal a.c. voltage feeds the transmitting coil, inducing a current in the receiver coil proportional to the medium's conductivity.
