What are the essentials of the checkweigher for the environment in use
The environmental conditions that affect the weighing accuracy and efficiency of the checkweigher mainly include: temperature, dust, vibration, air flow, electrical interference, characteristics of the product being weighed, humidity and equipment cleaning, and explosion hazard locations. For what type of checkweigher is required for a specific environment, the supplier of the checkweigher should be consulted to get the best solution. 1. Temperature In any application, the ambient air temperature around the checkweigher should not exceed 55℃. The materials on the checkweigher are isolated from all electronic components, so materials with a higher temperature than the ambient temperature are allowed to be transported. A typical checkweigher can transport materials with a temperature of 100°C. After special measures are taken, it is also possible to transport materials with a temperature of 200°C. Extremely high temperature and temperature fluctuations will affect the weighing performance, such as the weighing of frozen and refrigerated products or heated products where the ambient temperature changes more than 10 ℃ every day. Very cold or very hot products may require special belts. Extreme temperature or large temperature fluctuations may cause condensation. In this case, it is necessary to use insulating and sealing materials to enhance the anti-condensation ability of the checkweigher to protect the junction box, controller, motor and load cell. The electromagnetic force recovery type load cell is temperature stable, and it is not sensitive to temperature changes. Relatively speaking, resistance strain type load cells are more affected by temperature changes, and this change will cause the accuracy of weighing to decrease. The use of an automatic zero-setting checkweigher machine can reduce the influence of temperature changes on the weighing performance. 2. Dust It is feasible to use the weighing part to isolate the dust directly adjacent to the checkweigher machine, or take measures to keep the environment of the production area around the checkweigher clean. Dust falling on the weighing part causes the zero point of the checkweigher to shift. If the dust continuously falls on the conveyor or platform, the checkweigher needs to be set to zero continuously. 3. Vibration Any vibration will cause the checkweigher to produce noise signals and deteriorate the weighing performance. The vibration may be caused by mechanical equipment or hoppers running nearby, or the checkweigher may be in contact with the front and rear conveyors. Although the checkweigher uses special software to automatically filter the external vibration interference, some of the vibrations are high-energy and low-frequency, and it is difficult to completely eliminate it through filtering. 4. Checkweighers with a small air flow symmetry range, due to high sensitivity, air flow from all directions will affect the display value of the checkweigher, so avoid air flow around the checkweigher, even people walking around quickly Or reaching out in the weighing part may cause fluctuations in the weight display value. The shield can shield the air flow and should be used when necessary. The above is to share with you the related issues about the application environment of the checkweigher. I hope it will be helpful to you. If you want to purchase related products such as the checkweigher machine, you can contact us.
