Kromschroder 84447250 Pressure Switch
The Kromschroder 84447250 is a high-precision gas pressure switch designed for critical monitoring of gas and air pressures in industrial combustion systems. As the direct replacement for DG6U-3, this pressure switch is engineered to detect extremely low pressure differentials, providing reliable switch-on, switch-off, or switch-over functions. Featuring an adjustable pressure range of 0.4 to 6 mbar, it allows for fine-tuned control via an integrated handwheel. This DG6U-3 pressure switch is suitable for positive pressure, negative pressure, and differential pressure applications, making it a versatile component for boiler fan monitoring and air-conditioning ventilation systems. Built for durability in demanding environments, the unit is SIL 3 and PL e certified, ensuring its performance in safety-critical installations. The 84447250 pressure switch utilizes screw terminals for secure electrical connections and is hydrogen-ready, supporting modern high-efficiency fuel applications with its NBR diaphragm and IP 54 rated enclosure.
- Precise Pressure Control: Features an adjusting range of 0.4-6 mbar, allowing technicians to set exact switching points for sensitive burner and HVAC applications.
- Universal Compatibility: Functions as a high-performance HVAC pressure switch capable of monitoring air, flue gas, and biologically produced methane.
- Industrial-Grade Reliability: Certified for use in Zone 1 and 2 hazardous areas with an appropriate isolating amplifier, maintaining combustion safety standards.
- Seamless System Integration: Designed with standard electrical screw terminals and Rp 1/4 or Rp 1/8 internal threading for straightforward installation in existing gas trains.
Common Questions
What is the difference between the DG and DG..T models?
The DG models, such as the Kromschroder 84447250, are the European versions whereas the DG..T models represent the US-specific versions. This unit is intended for applications requiring European certifications like CE and EAC.
Can the switching point be adjusted while the system is under pressure?
Yes, the switching point on the DG6U-3 0.4-6Mbar can be manually adjusted using the handwheel located on the front of the unit to match specific system requirements during commissioning.
What media are compatible with this pressure switch?
This Kromschroder pressure switch is compatible with gas, air, flue gas, and biogas for positive pressure monitoring, and air or flue gas for negative and differential pressure monitoring.
