1000 Bar Hydraulic Pressure Gauge with High-Speed Peak Hold Display

Why Did a $15,000 Scrap Problem Go Unnoticed by Analog Gauges?

A marine facility reported that their hydraulic press was cycling slower than expected. The analog gauge showed normal pressure readings, but parts were still coming out of specification. This discrepancy led to $15,000 in annual scrap costs. The facility needed a solution that could detect rapid pressure fluctuations that analog gauges miss.

The Physics Behind Analog Gauge Limitations

Bourdon tubes, the traditional mechanism behind many pressure gauges, act as mechanical low-pass filters with natural frequencies around 1-2 Hz. This means they cannot respond to rapid changes in pressure, making them inadequate for detecting short-term spikes or fluctuations that could affect precision and reliability. As a result, even when the needle appears stable, the actual pressure may be oscillating beyond acceptable limits.

How DR3710 Solved the Pressure Spike Detection Problem

To address this, we installed the DR3710 Digital Pressure Gauge. Unlike traditional gauges, the DR3710 uses 3.2kHz digital sampling, which captures these rapid changes accurately. This allowed us to identify and address the pressure spikes that were undetectable by their analog system. The gauge’s high response frequency is critical for pressure spike detection in hydraulic systems, where even millisecond bursts can cause defects. Moreover, the DR3710 offers a pressure range from -1bar to 2500bar, making it suitable for 1000bar pressure measurement applications common in marine hydraulics.

How Did the Facility Save $15,000 Annually?

With the new setup, the facility could now maintain tighter control over the hydraulic press’s operations. By capturing and analyzing pressure spikes, operators adjusted the press parameters to eliminate out-of-spec parts. Consequently, scrap costs dropped by $15,000 annually. The DR3710’s Max/Min peak value holder also helped technicians identify the exact spike magnitude, enabling proactive maintenance.
