Rosemount 2088 Pressure Transmitter

Fits continuous absolute or gauge measurement on process loops that need a compact in-line transmitter, 4–20 mA HART (or low-power 1–5 Vdc HART), and up to 50:1 rangeability.

Key advantages

Gauge and absolute — −14.7…10000 psi gauge; 0…10000 psi absolute (ranges 1–5).
±0.075% of span std — ±0.065% with high-accuracy option P8 (to 10:1 turndown).
HART 5/7 outputs — 4–20 mA HART (code S) or 1–5 Vdc Low Power HART (code N); HR7 for HART 7.
Flexible process connections — ½–14 NPT female std; DIN G½ / M20×1.5 / RC ½ options.

Typical applications

Compact absolute or gauge pressure points on process skids.
Loops standardized on Rosemount 2088 with HART or low-power HART.
Installations picking conduit entry and process connection at order.

Selection guide

Pressure type & range — Gauge −14.7…10000 psi; absolute 0…10000 psi (ranges 1–5). Pick the range that covers your calibrated span.
Accuracy — ±0.075% of calibrated span standard; ±0.065% with high-accuracy option P8 (to 10:1 turndown). Rangeability 50:1.
Output — 4–20 mA HART (code S); 1–5 Vdc Low Power HART (code N); HART 5 default / HART 7 option HR7.
Supply — 10.5–42.4 Vdc no load (4–20 mA); 5.8–28 V for Low Power.
Process connection — ½–14 NPT female (std); DIN 16288 G½ male; M20×1.5 male; RC ½ female.
Electrical entries — ½–14 NPT, M20×1.5, or G½ conduit entry.
Wetted materials — 316L SST or Alloy C-276 isolating diaphragm / process connection; silicone or inert fill.
Overpressure / burst — Overpressure: Range 1 120 psig; Ranges 2–4 2× URL; Range 5 15000 psi. Burst: Ranges 1–4 11000 psi; Range 5 26000 psi.
Process / ambient temperature — Silicone fill −40…+121 °C; inert −30…+121 °C (vacuum service limits apply). Ambient −40…+85 °C (with LCD −40…+80 °C).
Housing & IP — Aluminum (low-copper), painted polyurethane. NEMA Type 4X, IP66, IP68 when properly installed.

Common mistakes

Ordering standard ±0.075% when the loop needs option P8 (±0.065% to 10:1 turndown) — high accuracy is an order option.
Mixing Low Power supply (5.8–28 V) with a 4–20 mA HART loop design (10.5–42.4 Vdc no load).
Ignoring overpressure/burst by range (Range 1 overpressure only 120 psig; Range 5 burst 26000 psi) — match the range code to the process upset case.
Specifying 316L when media need Alloy C-276 — wetted material is a model-code choice.
Claiming hazardous-area coverage without the matching E/I/N/K option codes on the quote.
Leaving vacuum-service limits blank when fill is inert (−30…+121 °C) or absolute under vacuum.

When to RFQ / what to tell us

Pressure type (gauge / absolute) and required calibrated span + units.
Accuracy need (std ±0.075% vs P8 ±0.065%) and HART 5 vs HART 7 (HR7).
Output code S (4–20 mA) vs N (1–5 Vdc Low Power) and available supply.
Media, temperature, fill (silicone or inert), wetted materials, process connection.
Overpressure expectation, IP / area class, display/LOI, manifolds/remote seals, quantity, ship-to country.

FAQ

Q: Gauge or absolute — which 2088 configuration do I need? A: Gauge when the low side sees atmosphere; absolute when you need absolute zero. Ranges 1–5 cover both — state the type and span in the RFQ.

Q: When do I need option P8? A: When the loop needs ±0.065% of calibrated span (to 10:1 turndown) instead of the standard ±0.075%. Call out P8 in the RFQ if that accuracy is required.

Q: Which approvals can I claim? A: Only those in the OEM documentation and ordered codes: ATEX, IECEx, FM, CSA, CE. Hazardous-area protection is selected by E/I/N/K option codes.

Q: What should I send for a quote? A: Pressure type and span, accuracy option, output S vs N, media and temperature, wetted materials, connection, supply, area class, display, quantity. Compatible with systems using Rosemount 2088 if you need a drop-in check — we do not claim authorized-dealer status.
