Precautions for fault detection and control of weighing instrument controller
Electronic crane scales, automobile platform scales, electronic forklift scales, unique function electronic scales, Dongguan electronic platform scale weighing instrument maintenance key points: fault detection and analysis in the application of weighing instrument maintenance sensor, automatic technology weighing instrument common fault conditions have been After the main performance of the digital display of the terminal equipment of the system software, after the main performance of the common fault conditions, it is not necessary to blindly follow the trend and dismantle the weighing sensor. It should be the first to identify the common fault from which stage of the detection system. The following methods can be used: turn on the middle wiring terminal, and use a multimeter to check the working attitude of each sensor to distinguish whether a certain sensor has common faults. Use the described method to narrow down the common fault categories, find the common fault sensors and immediately grasp the operating conditions caused by the common faults and carry out fault detection. Therefore, common faults caused by sensors are often related to irregular applications or abnormalities in mechanical equipment; check the installation of weighing sensor mechanical equipment; clear equipment faults and use a shake meter to check whether the cable is damaged. The application characteristics and common faults of weighing instrument sensors are caused by: working temperature causes different hazards to weighing sensors of different levels. The temperature and natural environment of the sensor at the application site and the measurement verification work are far different. Therefore, when the user finds that the sensor has excessive temperature drift in the application, he should adopt a relatively stable temperature natural environment that effectively creates a part of its surroundings. . Zero shift caused by overweight and wheel weight. In application, if the force application plane is not parallel to the reference plane of the supporting point, the wheel load condition will be extreme. Overweight or wheel weight will cause a large plastic deformation in a certain part of the polyurethane elastomer, the zero point will suddenly increase, and the partial ground stress will exceed the strength limit, which will cause the sensor to be destroyed. The zero point transition caused by the influence of the magnetic field. If the application of the on-site indoor space magnetic field suddenly impacts or changes, it will cause a very large amount of magnetic induction potential difference to be excited on the bridge Internet or data signal coaxial cable, which will cause the sensor output to fluctuate. Common problems of weighing instrument sensor application: The display cover and the chassis grounding device ensure that the sensor itself has a stable zero potential difference; it is strictly forbidden to place hanging objects on the weighing platform to prevent the sensor from causing growth; always check whether the system software is unsatisfactory Condition: The ground potential difference grounding device should take into account the change of power engineering load and the hazard of lightning strikes. Weighing instrument sensor fault detection and common problems The basic principle of pairing of weighing sensor and weighing instrument A weighing electronic scale machine equipment, whether it is a weighing scale, a scale, a crane scale, a sorting scale, a packaging scale, etc., is unavoidable. Sensors and weighing instruments, so what are the correlations between the weighing sensor and the instrument panel? The following web editor will introduce the matching formula of the weighing sensor and the instrument panel in detail. The matching formula of the weighing sensor and the weighing instrument: the output sensitivity of the weighing sensor * the encouraging power supply voltage * the number of sub-myopia of the larger weighing scale of the scale * the number of sensors * the measuring range of the sensor For example: a weighing 50kg Packing scale, with 1000 measurement ranges for the larger myopia; the scale body uses 3 Z6FC3/50kg sensors, the measurement range is 50kg, the sensitivity is 2.0±0.008mV/V, the cable-stayed bridge electric working pressure is 12V; the scale uses AED9101C instrument plate. Ask whether the selected sensor can be paired with the dashboard.
