Huba Type 692 — industrial high-pressure differential transmitter

Unlike Huba low-pressure HVAC Types 401/450/699, the Type 692 is a robust ceramic industrial differential-pressure transmitter with process media connections and selectable pressure, material and output configurations. Applications extend to refrigeration, water pumps and industrial process flow.

Topic	Huba model specification	Engineering and QA consequence
Pressure measurement	Differential/relative range family 0–25 bar; common system-pressure variants 12, 25 or 50 bar	These are BAR-scale pressure classes: not a 0–25 Pa ventilation filter meter.
Dynamics	<5 ms response in current Huba model summary	The actual installed control loop and impulse lines may be slower.
Temperature and materials	Medium/ambient −15…+85°C; Al₂O₃ ceramic sensor, stainless/PVDF/brass process interface choices	Select seal, housing and port material by the actual process fluid; gas compatibility alone is not enough.
Overpressure/rupture	Bursting pressure listed as 1.5× selected system-pressure rating	Never use rupture rating as normal working differential pressure or independent overpressure safety protection.
Electronics	Standardized signal options selected by 692 ordering code; draw <20 mA per maker	Verify supply range and 2-/3-wire signal topology on the chosen 692 configuration drawing.

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.
