Honeywell Analytics XNX Universal Transmitter, UL 3/4 AL FF HRT MPD IR LEL - XNX-UTAV-FHIF1


XNX-UTAV-FHIF1 XNX Universal Transmitter, UL 3/4 AL FF HRT MPD IR LEL by Honeywell Analytics

XNX Universal Transmitter, ATEX M25 AL FF HRT FOR TOX/O2 SNSRThe XNX Universal Transmitter, now with HART EDDL, marks a new turn in gas detection from Honeywell Analytics. It supports the widest range of sensors on a common platform and offers a modular choice of inputs and outputs.

XNX is designed for flexible integration, simple installation, user-friendly operation and straight-forward maintenance. It is ideal for use with a range of gas monitoring controllers or industry standard PLCs. The introduction of our HART Enhanced Device Descriptor Language (EDDL) software provides users with an at-a-glance indication of the health of their gas detectors in the field.
