Fits dual-parameter liquid analysis where you need a Rosemount 56—two independent channels for pH/ORP, conductivity, turbidity, DO/chlorine/ozone and more, with built-in PID, USB logging, and HART or PROFIBUS DP options.
Key advantages
- Channels — Independent dual measurement
- Inputs — pH/ORP, ISE, conductivity, turbidity, DO/chlorine/ozone, flow, 4–20 mA
- Control — Built-in PID controller
- Logging — USB data / event logger
- Power/comms — 24 VDC or 85–265 VAC; HART or PROFIBUS DP
Typical applications
- Dual-sensor water treatment panels.
- Plant liquid analysis with local PID.
- Multi-parameter skids.
Selection guide
- Sensor pairing
- AC vs DC power
- HART vs PROFIBUS
Common mistakes
- Mixing incompatible sensor/transmitter codes.
- Ignoring relay/alarm I/O needs.
- Under-sizing enclosure for cable glands.
When to RFQ / what to tell us
- Sensors, power, comms.
- Quantity, ship-to.
