Kromschroder DG6T-21N Pressure Switch
Technical specs, application notes, replacement checks, and related model references.
Product Overview
The Kromschroder DG6T-21N is a highly sensitive and reliable gas/air pressure switch designed for continuous monitoring of gas trains and combustion air systems. Manufactured to precise German engineering standards, it triggers safe burner shutdown if the gas or air pressure deviates from the critical setpoints. The switch utilizes an advanced elastomer diaphragm and microswitch mechanism to ensure repeatable and drift-free actuation. It is a verifiable safety interlock required by EN 1854 and EN 12067-2, widely deployed across heavy-duty thermal process plants.

Selection Notes & Data Verification
The DG6T-21N 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.
