The inspection steps of the electromagnetic flow meter manufacturer for the sensor

Abstract: The information on the inspection steps of the sensor by the electromagnetic flowmeter manufacturer is provided by the excellent flowmeter and flowmeter manufacturer and quotation manufacturer. After a long period of research and guidance and strict inspection of the intelligent electromagnetic flowmeter, the inspection steps of the electromagnetic flowmeter sensor are introduced as follows: Test equipment: one 500MΩ insulation resistance tester and one multimeter. Test steps: 1: In the pipeline. More flowmeter manufacturers choose models and price quotations. You are welcome to inquire. The following is the details of the inspection steps of the electromagnetic flowmeter manufacturers for the sensor. After a long period of research and guidance and strict inspection of the intelligent electromagnetic flowmeter, the inspection steps of the electromagnetic flowmeter sensor are introduced as follows: Test equipment: 500MΩOne insulation resistance tester and one multimeter. Test steps: 1: When the pipeline is full of medium, use a multimeter to measure the resistance between terminals A, B and C, and the resistance between A-C and B-C should be as large as equal. If the difference is more than 1 times, it may be due to leakage of the electrode, condensation water adsorption on the outer wall of the measuring tube or in the junction box. 2: When the lining is dry, use MΩInsulation resistance between A-C and B-C measured by meter (should be greater than 200MΩ). Then use a multimeter to measure the resistance between terminals A and B and the two electrodes in the measuring tube (should be in a short-circuit connected state). If the insulation resistance is small, it means that the electrode is leaking, and the whole set of flowmeter should be returned to the factory for maintenance. If the insulation has decreased but there is still 50MΩThe above and the inspection result of step (1) is normal, it may be that the outer wall of the measuring tube is damp, and a hot air blower can be used to dry the inside of the casing. 3: Use a multimeter to measure the resistance between X and Y, if it exceeds 200Ω, the excitation coil and its lead wires may be open circuit or poor contact. Remove the terminal board for inspection. 4: Check the insulation resistance between X, Y and C, it should be within 200MΩAbove, if there is a drop, use hot air to dry the inside of the casing. In actual operation, the decrease of coil insulation will lead to increased measurement error and unstable output signal of the instrument. 5: If it is determined that the sensor is faulty, please contact the manufacturer of the electromagnetic flowmeter. Generally, it cannot be solved on site, and it needs to be repaired by the manufacturer. The above is the whole content of this article. You are welcome to inquire about the flowmeter selection and quotation of our factory. 'Inspection steps for sensors by electromagnetic flow meter manufacturers'
