Case Study: How DR3416 Solved Melt Pressure Instability
The Hidden Cost of Heat-Soaked Electronics
Our extruder was producing inconsistent sheet thickness. The melt pressure reading seemed normal, but the product quality said otherwise. We traced the issue to a faulty melt pressure sensor that couldn’t handle 400°C. Consequently, each replacement failed within two weeks, costing us $30,000 annually in maintenance and lost production. This was not a single design flaw but a systemic problem: the thermal environment was too extreme for standard electronics.
What Root Cause Analysis Revealed About Thermal Degradation
Standard electronics fail above 125°C, yet our melt zones run at 350°C+. The heat migrates up the stem, cooking the sensor’s circuitry. Therefore, traditional high temperature pressure sensors degrade quickly under such conditions. We conducted a root cause analysis and found that the thermal gradient caused material expansion and signal drift. This means that even though the pressure reading appeared normal, the actual measurement was inaccurate. In fact, the sensor’s diaphragm was experiencing thermal stress, leading to premature failure.
How DR3416 Solved the Melt Pressure Instability
We installed the DR3416 Melt Pressure Transmitter, which features capillary cooling to separate the electronics from the melt zone. This innovative design ensures accurate measurements even at 400°C+ temperatures. Specifically, the rigid stem or flexible capillary configurations allow installation in tight spaces. Additionally, the mercury-free filling ensures safety and environmental compliance. The sensor also provides standard electrical outputs, making integration straightforward. As a result, we achieved reliable 400°C pressure measurement without frequent replacements.
$30,000 Annual Savings: The Quantifiable Impact
After a few months of operation, product quality improved by 25%, and maintenance costs dropped by $30,000 annually. Moreover, the DR3416 eliminated unplanned downtime, boosting overall equipment effectiveness. The sensor’s high temperature limits (up to 400°C) matched our process requirements perfectly. Consequently, we now have confidence in our melt pressure readings, ensuring consistent sheet thickness.
