Dungs GW500A4 Flame Detector
Technical specs, application notes, replacement checks, and related model references.
Product Overview
The DUNGS GW500A4 is a highly precise, adjustable compact pressure switch engineered to monitor overpressure, underpressure, or differential pressure in gas and air systems. Recognized globally as an industry standard, it features a highly sensitive diaphragm and an AgAg gold-plated microswitch that trigger burner lockout upon detecting unsafe pressure deviations. Its compact design and exceptional repeatability make it indispensable for forced draft burners, boilers, and industrial furnaces.

Selection Notes & Data Verification
The GW500A4 page is structured for engineering comparison: confirm the product type, firing range, fuel type, operating mode, electrical supply, and safety approvals against the manufacturer datasheet before specifying the burner or component.
Burner.wiki normalizes product data for discovery and comparison, but final selection should account for combustion chamber backpressure, local emission limits, control sequence requirements, and site commissioning conditions.
