Certificado deCells Garantia 1. Conductivity 3. Cell is composed basically by two boards or two concentric cylinders(electrodes), with well defined geometry. The space between the boards or cylindres creates a solution collumn, being so the measurement is independent from the total solution volume. The boards or cylindres geomety used will be related to the solutions concentration for a better reading of different samples we vary the distance (and;or) the board section.
Certificado de Description Garantia 1. Mechanical 4. Based on process conditions, the cells must be build of material previously specified, such as: Stainless Steel 316, Epoxy or PTFE with radial electrodes or SS316 annulars, Platinum, Titanium or others depending on its resistance to the solutions chemical aggressiveness .

Certificado de Garantia 1. Installation 6. Before you install your conductivity cell, please verify for any possible bubbles and if the sample is constantly renewed. ELECTRICAL CONNECTION 1. Prepare the cell installation point in area that offers good stirring, it is preferred to be close to the equipment (maximum of 10 meters -32 feet ) and exempt of vibrations. 2. Verify if all threaded points are tied. 3.

Certificado (cont.) de Garantia 1. Installation 6. Insertion Type For a correct conductivity measurement, it is recommended to install the cell as shown on below Illustration. The liquid flow must go thru the Sensor and exit thru the holes located at the upper portion of the sensor. See indicative arrows shown below, showing the recommended liquid flow.
Certificado de Garantia 1. Maintenance 7. All OMEGA equipments, are shipped from factory tested and calibrated. When under operation, the Conductivity Cell must be maintained periodically (the frequency will depend on the process), which would be basically cleaning, or if necessary, a new calibration. Cleaning Dip the electrodes in cleaning solution for 40 seconds, then wash throughly with deionized water to avoid standard contamination, when it is time to perform a calibration.
Certificado de Garantia 1. Troubleshooting 8. 1) When Calibrating the equipment, the function is not complete Verify for humidity presence at probes header or at connection box of the equipment. Another possibility could be the equipments interconnection cable and cell being cut or in short. 2) Reading above Range First clean the cell and try to calibrate it.
