The installation and calibration method of the 120 ton weighbridge is as follows:

Choose installation location: The installation location of the weighing scale should be on a flat, sturdy, and vibration free ground to ensure its accuracy and stability. At the same time, the installation location should be far away from electromagnetic interference sources, such as high-voltage wires, transformers, etc.

Install the weighing scale body: Place the weighing scale body in the installation position and secure it to the ground with bolts. When fixing the main body of the weighing scale, it should be ensured that it is level to ensure measurement accuracy.

Install sensor: Install the sensor under the main body of the scale and secure it to the ground with bolts. When fixing the sensor, it should be ensured that the distance and angle between it and the weighing scale body are correct to ensure measurement accuracy.

After installation, calibration is required as follows:

Four corner error correction: Take 1/3 of the full load weight of the weighing scale and place them respectively in the direction of the weighing industry base of the weighing scale, and record the reading value of the weighing scale after stabilization.

Angle difference correction: Select 1/3MAX chips (MAX is the measurement range of the weighing scale), place the weights on the 4 corners of the cabinet countertop of the weighing scale, and weigh them separately. The reading errors of the 4 corners cannot exceed the allowable errors.

Indication correction: Select weights and place them in the direction of the weighing industry base of the weighing scale to test the indication of the weighing scale.

Linear correction: Select chips with 20% MAX and 60% MAX, place the weights in the middle of the cabinet countertop of the weighing scale, weigh them separately, and compare the readings with the weights. The fault cannot exceed the allowable fault.

Load capacity correction: It can be repeated error correction. Take the chip of the full scale and place it four times in the direction of the industrial base of the scale. Record the reading value of the scale after each stabilization and test the load of the scale.

Range error correction: Weigh the full scale evenly in 10 equal parts, set the calibration index value according to the quality of each equal part, place the weights in the direction of the industrial base of the weighing scale in sequence, and record the reading value of the stable weighing scale.

The above is the installation and calibration method of the weighbridge for your reference. For more information, it is recommended to consult a professional from Qingdao Shimei Weighing Instrument.
