XDT — configuration and lifecycle distinctions

Selection point	Model-specific evidence
Sensor/application	HTF aluminum oxide for continuous dry-gas moisture monitoring; family dew-point range −100…20°C.
Packaging	XDT-OEM board; XDT-PM panel-mount; XDT-NEMA enclosure, listed as NEMA 4/IP65.
Output options	Configurable analog current/voltage and RS232; optional two alarm relays with adjustable hysteresis.
Pressure correction	Displays at sensor pressure or a user-entered alternate pressure.
Lifecycle	Current manufacturer resource center marks XDT EX as no longer available; this is distinct from ordinary XDT.

Select enclosure, power, output and alarm options as one orderable configuration; not all features are present in every unit. The older brochure describes hazardous-location versions, but it does not prove present availability or approval of the unit being purchased. Confirm the exact certificate and installed interface separately. Set alarm hysteresis for dryer cycling without confusing it with measurement accuracy.
