JUMO ecoLine CR-PVC 202923

Technical data

JUMO ecoLine CR-PVC Conductive 2-Electrode Conductivity Sensor   202923 Series (former 2EL5... Series)   • 2-electrode principle • proven versions for industrial application • 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 6 bar at 25 °C   Brief description Conductivity sensors in the 202923 series are used, for instance, in general water engineering, air conditioning and refrigeration, drinking and bathing water, and in industrial rinsing and process water circulation. The PVC body material restricts their application to media temperatures up to 55 °C. Two variants with the cell constants K = 0.1 or 1.0 can be supplied. Versions with the popular thread sizes G 3/4" or G 1" as well as a pluggable style are available for installation. The pluggable version is appropriate for use, for instance, with suitable PVC tees in the nominal sizes DN 25, 32 and 40. It enables fast de-installation of the sensor for cleaning and maintenance. According to choice, the electrical connection is made either by a detachable connector or an attached cable. The overall construction and the wetted components are physiologically harmless. Stainless steel (K = 0.1) or special graphite (K = 1.0) is used as the electrode material. The temperature probe, which can optionally be integrated, simultaneously acquires the temperature of the medium, for temperature compensation in connected instrumentation amplifiers. Stainless steel variant K = 0.1 The sensor features 3 metallic pin electrodes. The two outer pins are electrically connected and form one pole of the 2-electrode conductivity sensor. The stainless steel pin in the middle is the counter electrode. This arrangement ensures highly accurate measurement with narrow stray fields. A temperature probe can be integrated into the middle pin. Graphite variant K = 1.0 Physical requirements necessitate using a special graphite as electrode material for high conductance measurement. The two graphite electrodes are completely integrated in the electrode shaft. The optional temperature probe is housed in a stainless steel sleeve that is immersed in the solution under test.   Principle of operation The 202923 series conductivity sensors are 2-electrode conductivity sensors. An a.c. voltage is applied by means of a transmitter. The current flowing through the liquid and the electrodes is determined by the conductivity of the liquid.
