Fits intelligent four-wire liquid analysis where you need a Rosemount 1056 with single or dual sensor inputs (pH/ORP, conductivity, chlorine, DO, ozone, turbidity) and two 4–20 mA outputs with HART or Profibus DP options.
Key advantages
- Inputs — Single/dual: pH/ORP/ISE, contacting/toroidal conductivity, Cl2, DO, ozone, turbidity, flow/current
- Outputs — Two 4–20 mA; HART or Profibus DP options
- Display — Large customizable backlit graphic of dual measurements + diagnostics
- Enclosure — Polycarbonate Type 4X / IP65; ~155×155×131 mm; ½ DIN
- Install — Quick Start; modular field boards; ~1.5–2.0 kg
Typical applications
- Dual-parameter water quality panels.
- pH + chlorine or conductivity pairs.
- Four-wire analyzer with digital bus options.
Selection guide
- Single vs dual boards
- Digital bus — HART vs Profibus DP
- Measurements — Sensor suite
- Mount — Panel/pipe/wall
Common mistakes
- Ordering 1057 when only two channels needed (or vice versa).
- Wrong measurement board codes.
- Ignoring ½ DIN cutout.
When to RFQ / what to tell us
- Measurement boards, bus, mount.
- Quantity and ship-to.
