Huba Type 450 — board-mount fast Δp, analogue versus I²C
Huba 450 is a small board-mount ceramic differential-pressure transducer for neutral air and gases. Unlike enclosure-mounted transmitter 699, it is designed for OEM PCB assembly; the manufacturer’s low-pressure variants have substantially different range, burst and interface constraints.
| Topic | Huba model specification | Engineering and QA consequence |
|---|---|---|
| Order ranges | Relative/differential family from approximately −1 to +100 mbar (check exact model variant) | Do not apply the widest 100 mbar to a low-span 3 mbar unit; specify span and positive/negative port limits. |
| Dynamics | <2 ms sensor response in official model listing | Very fast sensor does not make controller flow readings independent of filtering or tubing. |
| Electrical options | Amplified temperature-compensated analogue, or digital I²C depending on order; <5 mA supply draw | I²C clock ≤100 kHz per Huba guidance; pull-ups ≥1 kΩ and bus ≤200 pF; no standard industrial RS485 or native 4–20mA. |
| Installation/protection | PCB-mount IP00, polyamide housing, ceramic Al₂O₃ element and silicone diaphragm | Requires separately sealed system housing, proper pneumatic tubes and moisture ingress design. |
| Operating environment | Medium and ambient −20…+85°C; compensated −10…+80°C | Outside compensation interval accuracy may vary although parts may operate. |
Variant-specific specification and approvals
Before installing or certifying the device, verify exact Huba order code, system-pressure limits, process media, signal supply, output scaling, pressure ports, EMC and the final assembly’s applicable certificates. No general-purpose ATEX/IECEx approval is claimed on this page.
