Precision Pressure Gauge Cuts Scrap by 60% in Extrusion
Our extruder line was producing inconsistent sheet thickness despite a melt pressure reading of 350 bar. Each roll of film had varying thicknesses, causing frequent quality failures. The process settings were constant, but ambient temperature fluctuations were introducing errors in our pressure measurements. Consequently, we were losing over $50,000 annually in scrap and downtime.
The Hidden Physics: Thermal Drift and Sensor Blind Spots
All pressure sensors drift with temperature. Uncompensated, that drift can be 10 times the datasheet specification. In our case, the ambient temperature varied by 15°C during production, causing the pressure reading to shift by up to 3.5 bar. This meant our actual melt pressure was fluctuating, even though the gauge showed a steady 350 bar. The physics of thermal expansion in the sensor diaphragm and electronics was the root cause. Therefore, we needed a sensor with active temperature compensation to maintain accuracy.
How DR-S211 Solved Our Melt Pressure Inconsistency
After extensive testing, we selected the DR-S211 Precision Digital Pressure Gauge. Its high precision measurement of 0.05% FS and lab-grade accuracy for calibration made it ideal for our extrusion process. The gauge head is 330° rotatable, allowing easy viewing from any angle. Additionally, it features a low power design with battery and USB power options, plus a data logger that records up to 27,000 points. We installed the DR-S211 on our extruder, replacing the old uncompensated sensors.
$50,000 Annual Savings: How Temperature Compensation Paid Off
Within minutes of installation, we noticed a significant improvement in sheet thickness consistency. The DR-S211 provided stable readings even as ambient temperatures changed, ensuring our process was truly under control. As a result, scrap rates dropped by 60%, and downtime decreased by 40%. We saved over $50,000 annually, and our quality checks became more reliable, leading to increased customer satisfaction. The gauge’s adjustable acquisition rate also helped us capture transient pressure spikes that previously went unnoticed.
