Description
The Kromschroder DL5E-1 32Z (SKU 84444261) is an air pressure switch designed for monitoring minimum and differential pressure of air or non-combustible gases. It operates within a pressure range of 0.005–0.05 mbar and can withstand a maximum working pressure of 300 mbar. The switch functions in ambient temperatures from -20 °C to +85 °C and weighs 0.12 g. It features compact dimensions and is tested with a manometer to ensure accuracy. This component is certified to strict industrial standards.
Further details

|---|---|
| Application | ventilation and air conditioning systems; automation of burner and boiler installations; control of air and gas supply in process applications; maintaining safe pressure levels in industrial and commercial facilities |
| Electrical connection | faston 6.3x0.8 mm terminals and threaded fittings |
| Failure modes | torn diaphragm, blocked impulse tube, drifted setpoint |
| Installation requirement | ensure the impulse line is clean and the diaphragm is undamaged before fitting |
| Replacement criteria | medium, switching range and differential, type of connection, contact rating |
| Safety chain role | confirm that the fan is moving sufficient air through the burner before and during operation |
| Verification | verify that the replacement switch matches the switching range of the original |
Choosing and fitting
When selecting a replacement pressure switch of this type, verify that the medium (air or non-combustible gases) matches, the pressure range covers the required setpoint, and the connection type (thread or hose spigot) is compatible with the existing impulse line. Ensure the maximum working pressure of the new switch is at least as high as the system's maximum. Check the contact rating to match the burner control requirements. Before installation, confirm the impulse line is clean and the diaphragm is undamaged.
Signs of failure
Common failure modes for this type of switch include a torn diaphragm, a blocked impulse tube, or a drifted setpoint. These issues can cause the burner to lock out, as the switch fails to close, preventing ignition. Symptoms may mimic ignition problems. To diagnose, test the switch with a manometer to verify it operates at the correct pressure. Inspect the impulse line for blockages and the diaphragm for damage.
