Selection Guide
DG..U
Universal
For positive, negative, and differential pressure. Switches with rising and falling pressure.
DG..H
Max. Pressure
Locks off with rising pressure. Requires manual reset. Ideal for maximum pressure monitoring.
DG..N
Min. Pressure
Locks off with falling pressure. Requires manual reset. Ideal for minimum pressure monitoring.
Series Overview
The Kromschröder DG Series gas pressure switches are designed for monitoring extremely low pressure differentials. They trigger switch-on, switch-off, or switch-over operations if a set switching point is reached.
Key Features
- Adjustable Switching Point: Easy adjustment via a hand wheel with a scale in mbar.
- Versatile Monitoring: Suitable for positive pressure (gas, air, flue gas, biogas), negative pressure, and differential pressure (air, flue gas).
- Approvals: EC type-tested and certified, FM approved, and UL listed (DG..T versions).
- Safety: Silicone-free construction suitable for various industrial applications.
Models
- DG..U: Universal pressure switch for positive, negative, and differential pressure. Switches with rising and falling pressure.
- DG..H: Locks off with rising pressure. Requires manual reset. Typically used as a maximum pressure switch.
- DG..N: Locks off with falling pressure. Requires manual reset. Typically used as a minimum pressure switch.
- DG..T: US version with NPT connection and specific approvals.
These switches are essential for the safe and efficient operation of gas burners and gas appliances.
