Fits explosion-proof differential/level pressure where you need a Dwyer 3100 with ±0.075% FS accuracy, 4–20 mA HART, 100:1 turndown, and Class I Div I Groups A–D enclosure.
Key advantages
- Accuracy — ±0.075% FS @ 20 °C; stability ±0.125% FSO/yr
- Rangeability — 100:1 turndown (0–6 in w.c. range 20:1)
- Output — 4–20 mA with HART; supply 11.9–45 VDC
- Pressure — Max −14.5 to 2000 psi; burst 10,000 psi
- Enclosure — NEMA 4X (IP66); explosion-proof Class I Div I A–D; optional LCD
Typical applications
- Hazardous-area DP and level.
- HART-configured process points.
- Sites needing push-button zero/span.
Selection guide
- Range / DP vs level — Process span
- LCD — Optional 5-digit
- Approvals — FM / ATEX option
- Connection — ¼ in FNPT; dual ½ in conduit
Common mistakes
- Ignoring LCD ambient limits (−22 to 176 °F).
- Underspecifying burst vs system spikes.
- Skipping HART host tools for config.
When to RFQ / what to tell us
- Range, LCD, approvals.
- Quantity and ship-to.
