Ultra High Pressure Digital Gauge Solves Spike Detection Issue
The Problem
Our 2000-ton hydraulic press was cycling slower. The analog gauge showed steady pressure, but every part was out of spec. The needle wasn’t moving—but the pipe was screaming. This inconsistency led to a scrap rate of 12%, costing $48,000 in lost production time and wasted materials over three months.
Root Cause Analysis
Bourdon tubes, the mechanical low-pass filters in analog gauges, can only respond to pressure changes slower than their natural frequency (1-2 Hz). Consequently, they physically cannot capture sudden spikes or fluctuations that occur within milliseconds. In our press, transient pressure surges as high as 1500 bar were occurring, but the analog gauge only registered 1200 bar. This means the root cause—rapid pressure spikes—was invisible to our monitoring system. Specifically, these surges were caused by a sticking valve that released pressure in bursts, creating ultra high pressure digital gauge readings that demanded faster detection.
The Solution
To capture these elusive spikes, we switched to the DR3710A Ultra High Pressure Digital Gauge, which samples at 1000 Hz and has a response frequency of 3.2 kHz. First, we installed it at the press inlet. Then, we connected it to the SCADA system for real-time data logging. The DR3710A accurately measured pressure from -1 bar to 2500 bar, capturing peak values that the analog gauge missed. Notably, its Max/Min peak value holder function allowed us to record the maximum surge pressure, which reached 1500 bar. This ultra high pressure digital gauge provided the high-speed pressure spike detection needed to diagnose the valve issue.
Results & Validation
After replacing the faulty valve, the press cycling time returned to normal, and scrap rate dropped to 0.5%. Over three months, we saved $48,000 in lost production and scrap costs. Additionally, the DR3710A’s high accuracy (±0.1% FS) and 2500bar pressure measurement capability gave us confidence in monitoring future transient events. As a result, we now adjust processes in real-time to maintain consistent part quality.
