DR3704 Digital Pressure Gauge with Data Logger for SCADA Transient Capture
The hydraulic press was cycling slower. The gauge showed normal pressure, but the parts were out of spec. Every week, we had to scrap batches worth $25,000 due to inconsistent thickness and strength. We replaced every sensor in the loop—pressure transmitters, temperature probes, and flow meters—and still, the problem persisted.
PLC scan rates are optimized for process trends, not milliseconds. A 500ms scan misses anything shorter. We were looking at snapshots that averaged out the anomalies. The real issue was hidden behind each cycle, waiting to strike again.
During a routine maintenance check, we noticed an old data logger tucked away in the machine’s electronics bay. It had been logging every pressure change since installation but remained ignored by our SCADA system. We decided to give it another look and imported its 10ms interval logs into our analysis software.
We found that the DR3704 Digital Pressure Gauge with Data Logger was capturing pressure spikes as short as 80 milliseconds. These were not visible in the SCADA readings but were causing the hydraulic press to malfunction. Each spike, though brief, stressed the system enough to compromise part integrity.
Installed the DR3704 Pressure Gauge across all critical points, and within weeks, we saw a significant reduction in scrap rates. The new setup logged every pressure change, giving us real-time visibility into potential issues before they became catastrophic.
