Factors that damage the weighing instrument of condiments
Using a condiment weighing instrument to weigh the quantity and flow of dry bulk food condiments has the following advantages: not only can accurately measure the condiments of different capacities, but the weighing can accurately measure the quantity of condiments without the need to correct the pile of condiments. density. The weighing does not need to touch the condiments, making it suitable for accurate measurement of erosive condiments and running in erosive environments. This is also a widely accepted method of quantitative packaging product sales. So, which aspects will harm the scale of the condiment weighing instrument? You can look at it in detail based on the text. The moisture entering the terminal block of the weighing system will lead to the cables of each load cell and reduce the power capacitor in the middle of the power plug. This will cause the load cell excitation wire (the wire that transmits power to the control module) to couple with the power plug (the wire that transmits the signal to the terminal block), resulting in electrical noise that can damage the weighing accuracy. If there is moisture in your geographic environment, you should also use a load cell with tightness in both the strain gauge area and the cable channel. The area of u200bu200bthe strain gauge should be closed by arc welding and electric welding, and the cable channel is easy to get wet; because the moisture will be absorbed by the cable, there should be an arc welding and electric welding parts, which includes the airtightness of the laminated glass to the metal composite material.连接头。 Connection head. Weighing instruments that are subject to very large temperature changes or the distance from the terminal block to the net weight controller is more than 50 feet will be damaged by temperature fluctuations, which will cause a change in the resistance of the cable. This is likely to cause a change in excitation, which in turn will cause a change in the load cell signal. In order to prevent such temperature difficulties, a six-wire load cell cable can be used. The load cell cable allows the weighing controller to perform proportional readings on the load cell signal, ignoring changes caused by changes in excitation.
