Reliable digital pressure gauge for Demanding Industrial Applications
Digital pressure gauge solutions for demanding industrial applications. The DR3716 series delivers reliable performance.
The SCADA trend showed 50 bar steady. Then the relief valve lifted at 48 bar. Something was wrong with our measurement.
Digital pressure gauges are supposed to eliminate manual reading errors, but in my last project, we faced a challenge that highlighted their limitations. Our process ran smoothly until one day when the SCADA trend showed a stable 50 bar pressure. The morning shift operator logged everything as normal, but the relief valve lifted at 48 bar mid-shift. Something wasn’t right.
The Hidden Physics: Why Digital Gauges Can Still Drift
The root cause lay in analog-to-digital conversion and thermal drift. Even precision digital sensors can experience offset shifts due to temperature changes—up to ±0.5% per 10°C in some designs. This drift accumulates over time, causing the displayed pressure to diverge from the true value. In our case, the SCADA system recorded pressure spikes of 2500 bar during normal operations, which our analog gauge never indicated. The anti-interference pressure transmitter stopped the VFD noise, but it was clear that a more robust solution was needed to ensure reliable readings throughout all operational conditions.
The Solution: An Economical Digital Pressure Gauge for Analog Replacement
We installed the DR3716, an economical digital pressure gauge designed for analog replacement projects. This cost-effective pressure gauge features a clear LCD digital display, battery-powered operation with long battery life, multiple pressure unit conversion, zero clearing, and peak hold functions. Its digital signal processing filters out noise and compensates for thermal drift, maintaining accuracy within ±0.25% FS over a wide temperature range. Within two weeks of installation, we recorded no further instances of unexpected pressure spikes or relief valve activations.
