Celtron load cell error correction

Celtron load cell error correction: A key step in ensuring accurate measurement
In the fields of industrial automation, process control and material testing, accurate and stable weighing measurements are essential to ensure production quality and improve work efficiency. American Celtron load cell with its high sensitivity, stability and reliability, has won the favor of many industries around the world. However, in the process of use, due to various reasons, the load cell may have errors, then we need to take a series of measures to correct these errors, to ensure the accuracy of the measurement.
First, check and calibration
First of all, we need to regularly check whether the wiring mode of the load cell is correct, and the matching problem between the sensor and the device. Incorrect wiring and mismatched components can both cause sensor failures, resulting in errors. In addition, we also need to check the zero point and sensitivity of the sensor to ensure that it is in normal condition. If a problem is found, a new load cell should be replaced or calibrated in time.
For the STC-100KG Celtron load cell, we can use a specific calibration method to ensure its accuracy. When the displayed value of the secondary meter flow does not match the rated flow value, we need to record the flow deviation to correct the past output. During zero point calibration, we need to input the required time to the secondary flowmeter and start the scale body at maximum speed. Select the automatic calibration state on the auxiliary instrument and start zero calibration, ensuring that the zero calibration work is performed more than three times. In addition, we also need to pay attention to whether the speed display of the secondary instrument is consistent with the theoretical calculation value to ensure the accuracy of the measurement.
Second, Angle difference adjustment
In addition to inspection and calibration, we also need to adjust the Angle difference of the sensor. The Angle difference is the error caused by the incomplete level of the sensor installation position or the uneven force. In order to correct this error, we need to adjust the sensor level to the best state to avoid tilt. If the installation condition limits cannot fully adjust the level, we can improve the measurement accuracy through error compensation. Specifically, the junction box can be opened and all connections disconnected, the magnetic field can be adjusted using the position correspondence, or an external coil can be used to compensate for the unbalanced force caused by the tilt.
In some cases, if there is still an error in the sensor after adjustment and compensation, we can compensate by adjusting the internal linear potentiometer or replacing the strain gauge. This requires a certain understanding of the internal structure of the sensor and operational skills. In addition, we can also process the output of the sensor, including amplification, compensation, etc., to eliminate errors. After the adjustment, it is necessary to check the stability of the sensor to ensure its long-term reliable operation.
3. Fault detection and maintenance
In order to ensure the normal operation of the load cell and extend its service life, we also need to carry out regular fault detection and maintenance of the sensor. This includes checking the appearance of the sensor for obvious mechanical damage or deformation; The resistance value of the sensor is measured to ensure that it is in the normal range; And compare whether the sensor output is consistent with the actual weight. If an abnormal situation is found, we need to further analyze the cause and take appropriate measures to repair or replace it.
In short, correcting errors for Celtron load cells is a complex and important process. Through regular inspection and calibration, Angle adjustment and fault detection and maintenance measures, we can ensure the accuracy and stability of the load cell, thereby guaranteeing production quality and improving work efficiency.
