Stop False Alarms with Programmable Delay Timer Pressure Switches
Pressure switch solutions for demanding industrial applications. The DR3602 series delivers reliable performance.
The alarm tripped at 6:30 AM, but the operators knew it was a false alarm. Nuisance trips in the oil pump room were causing daily downtime. The culprit? A pressure switch without a delay timer, triggering on every cold-oil startup spike. Cold oil is viscous, creating transient pressure surges that are normal but can exceed setpoints. Without a delay, the switch treats these as faults.
We solved this with the DR3602, a pressure switch with delay timer that ignores brief startup spikes. Its programmable delay prevents false trips, while dual relays and optional 4-20mA/RS485 outputs integrate seamlessly. The adjustable hysteresis ensures stable operation, and the NEMA 4X pressure switch enclosure withstands harsh environments.
