Tired of Measurement Errors? DR3710A Is the Answer

Why Was Our Hydraulic Press Producing Out-of-Spec Parts Despite Normal Gauge Readings?

During a night shift, I noticed our hydraulic press cycling slower than usual. The analog gauge showed normal pressure, but every part was out of spec. This inconsistency was costing us $20,000 annually in scrap. We suspected a measurement error since the press had been performing reliably until then. Our team decided to investigate further by tracing back recent maintenance logs and cross-referencing data from multiple sensors.

The Hidden Physics Behind Analog Gauge Drift

Analog Bourdon tubes used in many gauges physically twist at their elastic limit near 2500 bar, causing permanent deformation and calibration drift. Consequently, this leads to inaccurate readings over time. The mechanical fatigue is inevitable in ultra-high pressure applications, as the metal tube gradually loses its elasticity. Therefore, relying on analog gauges for critical measurements can be risky.

How DR3710A Solved Our Pressure Measurement Inaccuracy

We installed the DR3710A Ultra-High Pressure Digital Pressure Gauge. It features a sputtered thin-film sensor with molecular bond, providing exceptional accuracy without mechanical fatigue up to 2500 bar. The solid-state design ensures no moving parts, making it robust for ultra-high pressure applications. Additionally, its digital sampling at 1000 Hz and peak-hold function enabled us to capture pressure spikes accurately, ensuring precise measurements throughout the cycle.

What $20,000 Annual Savings Meant for Our Production Line

After installing the DR3710A, we saw an immediate improvement in part quality, reducing scrap by $20,000 annually. Moreover, the gauge’s ability to capture pressure spikes at 1000 Hz allowed us to optimize the press cycle, increasing throughput by 12%. This means our return on investment was realized in less than three months.

Could Your Analog Gauges Be Hiding Costly Errors?

If you’re experiencing unexplained scrap or process variability, your measurement equipment might be the culprit. Consider upgrading to a digital ultra-high pressure gauge like the DR3710A to eliminate mechanical drift and capture critical pressure spikes.
