Honeywell Searchpoint Optima Plus 2108N5110H – Sampling, Hydrocarbon, UL / INMETRO, HART+4–20 mA
2108N5110H is a Honeywell Searchpoint Optima Plus sampling point IR (Hydrocarbon), UL / INMETRO, 3/4" NPT, 316SS, HART+4–20 mA, black-anodised flow housing with remote gassing cell (RGC). Order it when the sample is extracted to the head instead of diffusing through a weather cap.
Siblings: HART 2108N5110N, gas —, style 2108N4110H, approval 2108N5010H.

Why this part number
Sampling SKU 2108N5110H uses a flow housing, not the dust-barrier + weather housing + deluge shade pack. Pressurised pump rooms and cold-box bypasses take this number; open-deck diffusion points take the Standard sibling.
Spares and mates
2108N5110H is Searchpoint Optima Plus Sampling. The detector is 316SS point IR with the factory window or flow-housing kit. Matrix: product-2698. Do not substitute Sensepoint XCD cartridges or XNX personalities.
Typical applications
Park 2108N5110H on LNG boil-off sample taps, solvent-coater ovens and compressor seal-gas extracts. 4–20 mA goes to the fire-and-gas panel; HART is asset management.

Installation and service
Mount 2108N5110H on a rigid 316 stand sized for the nameplate mass. Entries are 3/4" NPT — do not retap. Land 4–20 mA on the fire-and-gas matrix; HART does not replace the trip pair. Pipe the flow housing into the sample line. Gas with the Hydrocarbon curve only.
FAQ
- Is 2108N5110H an XNX transmitter?
- No. 2108N5110H is the Optima detector head. Pairing with XNX needs a separate IR-personality transmitter.
- Spares?
- Use the family matrix; do not mix other IR-platform parts.
- Lead time?
- Lot-based.
- Typical output?
- Often 4–20 mA — confirm by ordered configuration.
- Vs Searchline Excel?
- Optima is point IR; Excel is open-path.
