Digital Pressure Manometer Solves Hydraulic Press Peak Issues

Our SCADA system showed a steady 48 bar, but the relief valve on our hydraulic press kept lifting at 50 bar. The analog gauge read normal, yet every part produced was out of spec. We traced the issue to a low-pressure analog gauge that couldn’t accurately measure peak pressures due to mechanical friction and hysteresis. In analog gauges, the delicate movement loses resolution at higher pressures, causing discrepancies between field and SCADA readings. This is because the bourdon tube and linkage system have inherent friction that dampens rapid pressure spikes, leading to false normalcy reports. We needed a solution that could capture transient peaks reliably.

We replaced the analog gauges with the DR3701 Digital Pressure Manometer, a handheld pressure gauge designed for field use. This portable pressure tester offers peak-hold functionality that captures maximum pressures accurately in real-time. Field technicians could now verify readings on-site without relying solely on remote monitoring systems. The DR3701’s differential pressure measurement capability allowed us to compare readings across multiple points, identifying pressure drops that analog gauges missed. Its 9V battery operation and automatic shutdown (1-15 minutes) made it ideal for extended field sessions.

With the DR3701, we identified that peak pressures during the pressing cycle reached 52 bar, exceeding the relief valve setting. We adjusted the process parameters to keep peaks below 50 bar, leading to a 25% reduction in scrap rates and a 1 hour reduction in downtime per week. The device’s parameter correction and zero point calibration features ensured accuracy over time, even in harsh factory environments.

For critical processes, relying on analog gauges can mask transient pressure events. The DR3701 digital pressure manometer provides the precision needed for low-pressure measurement (0-50 bar range) in hydraulic systems. Its portable handheld design allows technicians to perform field pressure measurement at multiple locations, ensuring system integrity. Consider integrating such devices into your maintenance toolkit to avoid costly production errors.
