Huba 605 — mechanical differential pressure selection
| Model selection parameter | Manufacturer-specific evidence |
|---|---|
| Switching pressure | 20–400 Pa relative or differential pressure; one-side proof pressure 5,000 Pa below 85°C, reduced to 1,500 Pa at 85–110°C. |
| Differential and repeatability | The published minimum switching differential is 8 Pa at the 20 Pa minimum setting; reproducibility listed as ±1 Pa. Actual hysteresis depends on setpoint. |
| Medium and temperature | Air and neutral gases; medium and ambient −30…+110°C. The device is not intended as a general liquid-pressure transmitter. |
| Contacts and electrical integration | Mechanical changeover contact (COM/NC/NO), not analog 4–20 mA; 6.3 mm or 4.8 mm AMP terminal variants. Check the detailed contact-load table for the switched circuit. |
| Ports, enclosure and mounting | Two Ø6.2 mm tubing connections; optional pressure-pulsation damping orifice. IP00 bare, IP30 contact guard, IP54 unsealed cover or IP65 sealed cover; mounting orientation must match the ordered calibration. |
Select the trip pressure and switching differential as a pair. A pressure contact can supervise fan or gas-fired appliance operation, but the complete burner/interlock safety function requires the correct gas-appliance approval and installation. Check the product-specific UL/DVGW documents rather than treating the ordinary catalog listing as an ATEX/IECEx certificate.
