Output
4–20 mA (2-wire); 0–5 VDC or 0–10 VDC (3-wire)
Supply
10–36 VDC (2-wire); 17–36 VDC or isolated 21.6–33 VAC (3-wire)
Process connection
Barbed dual size for 1/8 in and 3/16 in I.D. tubing
Display
Optional LCD local indication
Fits low differential air and gas pressure where you need a Dwyer 616W with ±0.25% FS accuracy, barbed tubing connections, optional LCD, and NEMA 4X (IP66) polycarbonate enclosure.
Key advantages
- Ranges — About 0–6 to 0–100 in w.c.; bidirectional ±3/±5/±10 in w.c.; metric kPa models
- Accuracy — ±0.25% FS @ 77 °F; display ±0.5%
- Outputs — 4–20 mA 2-wire; 0–5 or 0–10 VDC 3-wire
- Connection — Barbed dual size for 1/8 and 3/16 in I.D. tubing
- Features — Digital push-button zero/span; optional LCD; NEMA 4X IP66
Typical applications
- HVAC and cleanroom low DP.
- Filter monitoring on air.
- Building automation DP points.
Selection guide
- Range / bi-directional — in w.c. or kPa
- Output — mA vs 0–5/0–10 V
- LCD — Local indication yes/no
- Response — Instantaneous vs 3 s
Common mistakes
- Using on liquids — service is air/non-combustible gases.
- Wrong tubing ID on barbs.
- 3-wire voltage on 2-wire-only supply.
When to RFQ / what to tell us
- Range, output, LCD.
- Quantity and ship-to.
