Fits outdoor/industrial pressure points where you need a Dwyer 679 weatherproof transmitter covering 0–25 to 0–10,000 psi with ±0.25% FS accuracy and NEMA 4 / IP56 aluminum housing.
Key advantages
- Ranges — 0–25 to 0–10,000 psi (679-0…679-8)
- Accuracy — ±0.25% FS
- Output — 4–20 mA 2-wire (0.1–5.1 VDC variants documented); 9–30 VDC
- Wetted — 17-4 PH SS; 1/4 in male NPT
- Housing — NEMA 4 / IP56 aluminum; 1/2 in NPS conduit; ±15% zero/span
Typical applications
- Weatherproof field pressure.
- Higher-pressure industrial points to 10,000 psi.
- Conduit-wired outdoor panels.
Selection guide
- Range — 679-0…679-8 chart
- Output — mA vs voltage variant
- Temp — Operating −40 to 260 °F
- Zero/span — Field adjust needs
Common mistakes
- Exceeding compensated −4 to 176 °F expectations for full accuracy.
- Media vs 17-4 PH.
- Wrong conduit seal practice for IP56.
When to RFQ / what to tell us
- Range, output variant.
- Quantity and ship-to.
