JUMO tecLine CR S01: Conductive 2-electrode conductivity sensor Data Sheet

2021-06-22
The JUMO tecLine CR S01 sensors acquire the electrolytic conductivity of a measuring liquid according to the conductive 2-electrode measuring principle. A transmitter supplies the electrodes with an alternating voltage. The current flowing through the measurement medium depends on the medium's conductivity. An integrated temperature probe (either Pt100 or Pt1000) simultaneously acquires the temperature of the measuring liquid.
The sensors are available in two design types, which differ in terms of their geometry and the cell constant K. The version with K = 1.0 covers a wide measuring range of 1.0 to 5000 μS/cm (5 mS/ cm). The version with K = 0.1 can be used in a range of 0.1 to 1000 μS/cm. The electrodes of these sensors are made from stainless steel 1.4404 and are set in a PEEK (polyether ether ketone) body, which offers a high level of chemical resistance. Another feature of these sensors is their resistance to heat and cold, with an area of application between -40 and +100 °C.
The sensor housing is based on a cable fitting according to DIN EN 62444 and ensures that the sensor has a compact size. As a result, the sensor can also be installed in hard-to-reach areas. With immersion lengths between 22.5 and 44.5 mm, the sensors can also be installed in pipes with small nominal widths.
Process connections featuring a globally standardized metric thread (M20 × 1.5) or standardized self-sealing NPT thread (1/2") ensure that the sensor can be mounted easily and reliably.
●Application:
The sensor is suitable for universal use, for example:
■Drinking water, service water, and wastewater applications
■Refrigeration, air-conditioning, and cooling system construction
■Reverse osmosis plants
■Industrial rinsing processes involving a low level of pollutants
■Horticultural technology
■Industrial water applications
■Chemical industry
■Food and beverage industry It is possible to select different materials for the process connection, such as nickel-plated brass or corrosion-resistant stainless steel, meaning the user can select the ideal sensor for their particular application.
The "Sensor selection guide" table on the next page is intended to help users make their selection.
●Special features:
■Robust, compact process sensor, also suitable for small nominal pipe widths
■Wide measuring range (0.1 to 5000 μS/cm)
■Resistant to heat and cold at temperatures between -40 and +100 °C
■Simple installation
■Protection type IP68
■Provides good chemical resistance to aggressive media
■Easy to clean
