Process connection
1/4 in male or female NPT and BSPT
Electrical connection
3 ft cable or 4-pin M-12 connector
Fits intrinsically safe pressure loops where you need a Dwyer IS626 with 0.25% FS accuracy, 4–20 mA output, 316/316L SS wetted parts, and Class I Div 1 IS approvals.
Key advantages
- Accuracy — 0.25% FS (absolute 0.5% FS)
- Output — 4–20 mA; 10–28 VDC; 50 ms response
- Ranges — Gauge examples 15–1500 psig; absolute models in chart
- Wetted — Type 316 / 316L SS
- Approvals — cULus IS UL 913; Class I Div 1 A–D; Class II/III; T4 @ 80 °C; NEMA 4X
Typical applications
- IS-rated gas/liquid pressure.
- Any-orientation industrial mounts.
- Cable or M12 electrical plants.
Selection guide
- Range code — IS626 chart
- Connection — 1/4 in MNPT/FNPT/BSPT
- Electrical — 3 ft cable vs 4-pin M12
- Barrier — IS system design
Common mistakes
- Installing without proper IS barrier/entity match.
- Absolute vs gauge mix-up.
- Ignoring 0–176 °F ambient band.
When to RFQ / what to tell us
- Range, connection, electrical.
- Quantity and ship-to.
