Calibration and Maintenance of Pressure Sensors in Extrusion

The reliability and accuracy of pressure sensors are crucial for the quality of extrusion processes. Regular calibration and maintenance are essential to ensure optimal performance. Here are some important steps and tips for maintaining your pressure sensors.

1. Preparation: Turn off the extrusion system and allow it to cool. Carefully remove the pressure sensor to avoid damage.
2. Use a Reference Device: Use a calibrated reference device to check the measurements of the sensor being calibrated. Ensure the reference device is suitable for the same pressure range.
3. Comparison Measurement: Connect the pressure sensor and the reference device to a pressure source. Gradually increase the pressure and compare the readings of both devices at different pressure levels.
4. Adjustment: If deviations are found, adjust the pressure sensor according to the manufacturer's instructions to restore accuracy.
5. Documentation: Record all calibration results and adjustments in a log. This facilitates future calibrations and tracking of sensor performance.

1. Regular Inspection: Regularly inspect your pressure sensors for signs of wear or damage. Look for cracks, corrosion, or loose connections.
2. Cleanliness: Keep the sensors clean and free from contaminants. Use appropriate cleaning agents that do not damage the sensor elements.
3. Environmental Protection: Ensure sensors are protected from extreme temperatures, humidity, and chemical influences. Use protective housings or covers if necessary.
4. Keep Spare Parts Handy: Always have spare sensors and calibration devices available to minimize downtime in the production process.
