All of the essential information about the calibration cycle following the repair of a hot runner displacement sensor is already present in the existing web content, which eliminates the necessity for a new search. The recalibration cycle for repaired hot runner displacement sensors can be implemented in accordance with the following standards, considering your previous focus on drift prevention and defect repair of hot runner displacement sensors:
I. Conventional Calibration Procedure
Basic Cycle: To guarantee long-term, stable measurement accuracy, conduct regular calibration every six months under normal operating conditions following repair and accuracy verification.
High-Load Conditions: Calibration should be conducted every three months in workshops with strong vibration/electromagnetic interference or in scenarios where the hot runner operates continuously for 24 hours.
Low-Load Conditions: In intermittent production scenarios where the hot runner is operated for less than 100 hours per month, calibration can be extended to every 12 months.
II. Special Scenarios That Initiate Immediate Calibration
Immediate calibration is necessary following the occurrence of a severe impact or a strong electromagnetic shock to the sensor.
Simultaneously, sensor calibration is implemented subsequent to the heated runner's thermal expansion lock-up or overheating.
Sensors that demonstrated abnormal data spikes and signal drift were calibrated immediately following the troubleshooting process.
All calibrated sensors were uniformly calibrated during the annual significant equipment overhaul of the production line.
III. Supplementary Requirements for Compliance Scenarios The relevant requirements of the National Metrological Technical Specification JJF 1305-2011 must be satisfied in order to ensure that injection moulding production lines in industries such as automotive and medical are precision compliant. In general, the calibration cycle for repaired sensors should not exceed 12 months, and all calibration documents must be archived for traceability. This policy guarantees that measurement data is traceable to national metrological standards.
This calibration cycle standard is entirely compatible with the low-cost Hall effect displacement sensors that you have selected for domestic production. This ensures monitoring accuracy and minimises unnecessary downtime for calibration.
