DR3710A Ultra-High Pressure Digital Gauge (2500bar)

Why Our Process Line Kept Failing (And How DR3710A Fixed It)

Our hydraulic press ran smoothly for months. However, it suddenly started cycling much slower. Strangely, the gauge still showed normal pressure readings. As a result, the finished parts were completely out of spec, and our team could not quickly find the root cause.

At high pressures from 1600bar to 2500bar, mechanical Bourdon tubes operate near their physical limits. Consequently, they suffer from mechanical wear and sensor drift. This mechanical fatigue leads to inaccurate readings and unexpected equipment downtime over time.

Uncovering the Hidden Pressure Drift

After days of troubleshooting, we decided to inspect the system more deeply. Although the old gauge showed normal pressure values, the press behavior was clearly wrong. Therefore, we realized that mechanical fatigue was hiding the actual system pressure.

To solve this issue, we upgraded to the DR3710A digital pressure gauge. This high-pressure sensor relies on thin-film strain gauge technology, which provides stable readings without any mechanical wear.

Real-Time Results on the Factory Floor

We installed the DR3710A directly on our main hydraulic line. Because this digital gauge uses 1000Hz fast sampling, it captures sudden pressure spikes instantly.

After the upgrade, our process quality improved immediately. The finished parts met all quality specs, and our cycle times became stable again. In addition, maintenance costs dropped significantly because the new solid-state sensor requires far less calibration.
