2-electrode principleproven versions for industrial use measuring ranges 0 ... 1 mS/cm (K = 0.1) or 0.01 ... 15 mS/cm (K = 1.0) temperature range up to 55 °C, maximum pressure up to 6 bar at 25 °C JUMO ecoLine CR-PVC conductive 2-electrode conductivity sensorBrief description: Conductivity sensors of the 202923 series are used, for example, in general water technology, cooling and air-conditioning systems, drinking and bathing water, or in industrial rinsing and process water circuits. The body material PVC limits the application to medium temperatures up to 55 °C. Two versions with cell constants K = 0.1 or 1.0 are available. Versions with the common thread sizes G 3/4" or G 1" or a plug-in version are available for installation. The plug-in version is used, for example, with the matching PVC tees in nominal sizes DN 25, 32 and 40 and allows the sensor to be quickly dismantled for cleaning or maintenance. The electrical connection is made either via a detachable device plug or via a fixed cable connection. The overall construction and the parts in contact with the medium are physiologically harmless. The electrode material is stainless steel (K = 0.1) or special graphite (K = 1.0). The optionally integrable temperature sensor allows simultaneous recording of the medium temperature for temperature compensation in downstream measuring amplifiers.Stainless steel variant K = 0.1 The sensor has 3 metallic pin electrodes. The two outer pins are electrically connected and form one pole of the 2-electrode conductivity sensor. The counter electrode is the middle stainless steel pin. This design achieves very high measurement precision with low stray fields. A temperature sensor can be integrated in the middle pin. Graphite variant K = 1.0 For physical reasons, special graphite is used as the electrode material for higher conductance values. The two graphite electrodes are completely integrated in the electrode shaft. The optional temperature sensor is located in a stainless steel sleeve that is immersed in the measured medium. Operating principleThe sensors of the 202923 series are 2-electrode conductivity sensors. An AC voltage is applied to them by the transmitter. The current flowing across the liquid and the electrodes is determined by the conductivity of the liquid

Our Neomeris conductivity cell with 12mm connection is used for the determination of the electrical conductivity in aqueous solutions. Inside the T-piece is the two-electrode measuring cell without temperature compensation. The installation is easy and fast due to the John Guest connectors. We recommend the use of the product in the fields of distillate, condensate, ultrapure water as well as fully demineralized water.

Capacity measurement ion exchanger cartridgeOur Neomeris N-FLASH10 conductivity meter in a T-piece with 3/8 inch connection is a conductivity measuring instrument that is used to monitor the electrical conductivity of water after flowing through the ion exchanger cartridge. The measuring instrument including the integrated measuring cell is battery operated and permanently installed in the T-piece. If the measured electrical conductivity is below the limit value of 10µS/cm, the green LED flashes; if it is above, the red LED flashes, indicating that a cartridge or resin change is required. Due to the T-piece used, the measuring device can also be integrated very easily and is optimally installed in the liquid flow for a stable measurement. Measuring principle: The measuring cell generates an electrical signal that is proportional to the conductivity of the liquid. This signal is processed in the device and the LED is controlled via the programming stored in the device. Application: Conductivity meters are often used in water treatment plants in the process industry.Technical data:Screw-in thread: 3/8"; others available upon requestMaterial housing: POM black Material lid: Plexiglas Material electrodes: V4A 4571 Material O-ring: EPDM Cell constant: C= 0.6 +/- 10% Max.
