Case Study: How DR3704 Solved Transient Pressure Capture at Steel Process
Case Study: How DR3704 Solved Transient Pressure Capture at Steel Process
The $25,000 Monthly Scrap Problem No One Saw Coming
Our hydraulic press was cycling slower. The gauge showed normal pressure, but every part was out of spec. It was clear that something was amiss, yet the SCADA system didn’t reveal any immediate issues. This discrepancy was costing us $25,000 per month in scrap and unscheduled downtime. We needed to find the root cause fast.
What SCADA Didn’t Tell Us About Our Hydraulic System
PLC scan rates are optimized for process trends, not milliseconds. A 500ms scan misses anything shorter than a heartbeat in industrial machinery. A 200 ms pressure spike could be critical but invisible to our monitoring systems. During maintenance rounds, we noticed that the hydraulic lines were under more stress than usual. The team suspected transient pressures that the gauges might have missed. We began investigating by collecting data from various points around the press. As a result, we realized that conventional pressure transmitters with slow update rates simply cannot capture fast transient events. This means that even with a robust SCADA system, brief pressure spikes can go undetected, causing cumulative damage over time.
How DR3704 Solved Our Transient Pressure Capture Problem
We installed the DR3704 Digital Pressure Gauge with Data Logger on several key nodes of our system. Its onboard logging at 10ms intervals captured what SCADA never saw, providing us with detailed pressure trends that we couldn’t get any other way. The DR3704 is a digital pressure gauge with logging capabilities, specifically designed for capturing transient events. It features built-in data logging for pressure trend analysis, SD card storage with CSV file format export, and high accuracy measurement. Additionally, it is battery-powered with a 3-5 year battery life, has a protection class of IP66, and offers large memory capacity for long-term recording. Data export for PC analysis made it easy to review and share findings. For more on transient pressure capture, see [Control Engineering’s guide](https://www.controleng.com).
$25,000 Monthly Savings: The Quantifiable Impact
Within days, the data from the DR3704 revealed multiple instances where pressures spiked beyond normal ranges, but only for brief periods. These transient spikes were causing rapid wear on our hydraulic components and leading to parts out of spec. Since implementing the DR3704, we’ve seen a significant improvement in part quality. Consequently, the cost of downtime due to scrap has dropped by $25,000 per month. We also increased the efficiency of maintenance scheduling by identifying problem areas that weren’t obvious from SCADA data alone. Notably, the DR3704 paid for itself within the first month of use.
