Process Of Calibrating Concrete Bathing Plant
Step1 Preliminary Preparation
Confirm the equipment and sensors that require calibration, such as weighing sensors, ingredient scales, moisture sensors, etc.
Prepare the necessary tools and equipment for calibration, such as calibration weights, standard measuring instruments, calibration software, etc. Check if the power supply, air source, etc. Are normal to ensure that the calibration process is not affected by external interference.

Prepare the necessary tools and equipment for calibration, such as calibration weights, standard measuring instruments, calibration software, etc.
Check if the power supply, air source, etc. Are normal to ensure that the calibration process is not affected by external interference.
Step2 Zero Calibration
Empty all sensors and materials on the concrete batching plant and scale body to ensure that the scale body is in an unloaded state.
Start the control system of the batching plant and enter calibration mode.
According to the calibration software or device prompts, perform zero point calibration on the scale body, to ensure that the reading is zero when the scale body is unloaded.
Step3 Weighing Calibration
Place certain calibration weights on the scale body and record the readings displayed by the control system.
Compare the reading displayed by the control system with the actual weight of the calibration weight, then calculate the error value.
Adjust the parameters of the control system according to the error value, to make the reading displayed consisted with the actual weight of the calibration weight.
Repeat the above steps and perform multiple calibrations by different calibration weights, to ensure the accuracy.
Step4 Record And Review
During the calibration process, record in detail the calibration data, error values, and adjustment parameters for each step.
After calibration is completed, the data is reviewed and organized to form a calibration report.
The calibration report should include information such as calibration date, calibration personnel, calibration equipment, calibration data, error values, and adjustment parameters. It is should be stamped with the signatures and official seals of relevant personnel.
Step5 Subsequent Maintenance And Inspection
After calibration is completed, regularly inspect and maintain the equipment and sensors of the mixing plant to ensure they are in good working condition.
Regularly or irregularly re-calibrate the mixing plant according the usage to ensure the accuracy and reliability of measurement data.
How Often Does Calibration Of Concrete Batching Plant Operated
The calibration frequency of concrete batching plant is not fixed and is influenced by various factors, including operational requirements, management standards, equipment usage conditions, etc.
Generally speaking, it is recommended that the mixing plant conduct self caibration every day to ensure the quality of concrete production. The calibration cycle of the ready mix plant scale may vary.
Some production companies require calibration of the batching plant scale at least once a year, but important and frequently used mixing plants may require more frequent calibration, such as once a month.
In addition, concrete mix plants are used in harsh environments need more frequent detection and calibration. The harsh environments here refer to those with high temperature, low temperature, and dusty air, where the weighing accuracy is easily affected.
What’s more, in China, according to normative documents, newly purchased and repaired measuring scales should be calibrated before being put into use; The measuring scale with built-in calibration device is calibrated every 12 months; Metrological scales calibrated manually or externally should be calibrated every 6 months.
Cautions For Calibration Of Concrete Batching Plant
When calibrating the concrete batching plant , it is also necessary to pay attention to the following points:
Calibration should be carried out by professional technicians to ensure the safety and accuracy of the calibration process.
Before calibration, carefully read the manual of the concrete batching plant and related equipment to understand the specific requirements and steps of calibration.
During the calibration process, it is necessary strictly follow the instructions and calibration software requirements to avoid equipment damage or calibration failure caused by misoperation.
After calibration is completed, the calibration data and results should be carefully recorded, and the calibration report and records should be properly kept.
The above content is for reference only, and the specific tools and equipment required may vary depending on the model, specifications and calibration requirements of the batching plant.
