Capture Pressure Spikes Your Analog Gauge Misses

2500 bar pressure measurement solutions for demanding industrial applications. The DR3710 series delivers reliable performance.

Every time, the gauge read smoothly and steadily. Yet, the relief valve on the pressure vessel lifted unexpectedly.

Bourdon tubes, our go-to for decades, act as mechanical low-pass filters. They can only respond to pressure changes at a natural frequency of 1-2 Hz. On that night shift, we faced an anomaly—a sudden pressure spike detection event that was too fast for our conventional gauges to capture.

The Solution: Digital Pressure Gauge for Spike Detection

We upgraded the setup with the DR3710, a digital gauge designed for ultra high pressure digital gauge applications. This digital marvel samples pressure 1000 times per second, ensuring no peak is missed. The DR3710’s response frequency of 3.2 kHz allows it to detect transient events our analog gauges would have otherwise overlooked. Physically, the sensor uses a strain-gauge-based diaphragm that converts pressure to an electrical signal with minimal mechanical damping, enabling faster response than Bourdon tubes.
