Precision Pressure Gauge with 0.05% Accuracy for Extrusion

The Problem: Inconsistent Sheet Thickness Despite Stable Pressure Readings

Our extrusion line ran at 400°C. But the sheet thickness varied by as much as 15% from target. This happened even though the melt pressure gauge showed a steady 350 bar. In just one month, our R&D team saw repeated quality failures. We lost over $20,000 in rejected material.

What Was the Real Cause?

The root cause was temperature drift in the pressure sensors. Nearly all pressure sensors drift when temperatures change. If not corrected, this drift can be 10 times higher than what the datasheet says. In our lab, even small shifts in room temperature (±5°C) caused enough drift to hide real pressure changes. That led to uneven sheet thickness.

Our Solution: A Temperature-Compensated Pressure Gauge

We needed a precision pressure gauge that stays accurate despite temperature swings. After looking at several options, we installed the DR-S211 Precision Digital Pressure Gauge. It is also well-suited for the calibration of pressure gauge systems in industrial environments. The DR-S211 has active temperature compensation. This keeps 0.05% full-scale accuracy from -40°C to 85°C. So you can trust the readings in hot or cold conditions. That lab-grade accuracy makes it a great choice for the calibration of pressure gauge standards in critical processes.

The Results: Less Scrap, Better Consistency

Within one week, sheet thickness became much more consistent. We cut scrap by 80%. The gauge also has a data logger that records up to 27,000 points. That helped us see how pressure changes relate to thickness over time. Its large 5-digit display is easy to read, even in dim light. Plus, the head turns 330°, so it fits easily in tight spaces. You can adjust how often it reads data, and it runs on low power—either battery or USB. That makes the DR-S211 useful in the lab or out in the field. It also supports 10 pressure units, so it works with your existing systems. For regular calibration of pressure gauge tasks, its stable readings save time and reduce errors.

Why Choose the DR-S211?

If you need a temperature-compensated pressure gauge with 0.05% accuracy, the DR-S211 is a smart choice. It fixed our process and simplified the calibration of pressure gauge process across our plant.

Ask yourself: How many batches have failed because of temperature drift you never fixed?
