DR3710A Ultra-High Pressure Digital Pressure Gauge up to 2500 Bar

Why a $40,000 Scrap Problem Was Hiding in Plain Sight

On a critical night shift, our team was calibrating a hydraulic press for an urgent defense project. The press cycled slower than usual, yet the analog gauge showed normal pressure. However, parts consistently failed specification—a clear sign of measurement error. The scrap cost had ballooned to over $40,000 annually, and we couldn’t pinpoint the root cause. This hidden cost was unacceptable for our operations.

The Physics of Analog Gauge Failure at 2500 Bar

Traditional Bourdon tube gauges rely on mechanical deformation to indicate pressure. At ultra-high pressures near 2500 bar, these tubes reach their elastic limit, causing permanent twisting and calibration drift. As a result, readings become increasingly inaccurate over time. This means operators unknowingly produce out-of-spec parts, leading to costly rework and material waste. The fundamental issue is mechanical fatigue—a problem inherent to analog designs.

How DR3710A 2500 bar Pressure Gauge Solved Our Measurement Inaccuracy

We replaced the failing analog gauge with the DR3710A Ultra-High Pressure Digital Pressure Gauge. Its sputtered thin-film sensor uses a molecular bond to attach the strain gauge directly to a 17-4PH stainless steel diaphragm. This solid-state construction has no moving parts, eliminating mechanical fatigue. Additionally, the sensor captures pressure spikes at a 3.2 kHz response rate, providing real-time data that analog gauges miss. The laser-welded housing ensures durability even under extreme conditions.

What a 90% Reduction in Scrap Costs Looks Like

After installing the DR3710A, scrap rates dropped from $40,000 to under $5,000 per year—a 90% reduction. The gauge’s ±0.2% FS accuracy and 1000 Hz digital sampling gave us confidence in every reading. Consequently, our hydraulic press now operates efficiently, and we meet defense project deadlines without rework. The investment paid for itself within months.
