Recently, our Service Crew was called to address a critical issue at a Maryland University involving an improper drum pressure reading. The investigation led to the discovery of a damaged transducer, which was unprotected due to the absence of a siphon pigtail. This small yet crucial component plays a significant role in maintaining the reliability and safety of pressure controls.

The Importance of Siphon Pigtails

• Temperature Protection: Siphon pigtails act as a barrier, preventing high-temperature media from directly reaching the controller. This helps in avoiding overheating and extends the lifespan of the pressure control.
• Condensation Prevention: Their coiled or U-shaped design traps condensate, keeping it from entering the pressure control. This eallows for more accurate readings and smoother operation.
• Pressure Equalization: They help dampen sudden pressure spikes, allowing for more stable and accurate pressure measurements.
• Fluid Separation: Siphon pigtails keep contaminants and impurities present in the steam piping away from the pressure control, which reduces the risk of damage.

After installing a new transducer and the essential siphon pigtail, our crew quickly brought the system back online, now equipped for a longer operational life.

It’s the small details like these—whether it’s missing pigtails, loose ground wires, or other overlooked aspects—that can delay commissioning and compromise system reliability. At Preferred, we ensure every component is in place, keeping your systems running smoothly.
