How We Solved Our Pressure Switch Reliability Problem

Pressure switch solutions for demanding industrial applications. The DR3511 series delivers reliable performance.

The Challenge

Every month, the mechanical switch triggered false alarms 3 times.

Every month, the mechanical switch triggered false alarms 3 times. Meanwhile, our new DR3511 digital controller has been flawlessly setting points without any drift for over a year now.

We initially assumed that the frequent trips were due to a minor issue. We were wrong; we later learned that mechanical switches use springs, and every cycle causes slight setpoint changes leading to drift.

Now we rely on DR3511’s digital setpoints—no moving parts, no drift. How many production hours have you lost due to mechanical switch false trips?
