May 2017

Multi-parameter Transmitter for Liquid Analysis

The Rosemount 1056 Dual Channel Transmitter displays up to two independent liquid analytical measurements. HART and Profibus
DP digital communication options allow for connection to HART hosts and Profibus networks. Start-up and installation of the 1056 is
easy by using Quick Start Programming.

Rosemount 1056 Dual Channel Transmitter

Overview

May 2017

Independent Dual Input Measurements

 Expandable to two channels of liquid analytical

measurements: pH/ORP, Conductivity, Free Chlorine, Total
Chlorine, Dissolved Oxygen, Ozone, and Turbidity.

 Modular boards with auto-recognition of sensor board.

 Large, easy to read, user customizable display of dual

measurements in addition to diagnostic and temperature
readings.

Reduced Installation and Maintenance Time

 Shorter installation times using Quick Start programming at

initial install or after factory reset.

 Effortlessly connect with PLCs and DCS' by choosing the HART

or Profibus DP communication options.

 Display measurements, configure alarms, and conduct

maintenance with a simple to use local operator interface.

 Efficiently manage your devices using intuitive device

dashboards on AMS/475 Communicators.

Accurate, Linear and Reliable Measurements of
Analytical Sensors

 Faster calibration of pH sensors using auto pH Buffer solution

detection.

 Linear conductivity measurements with on-board

concentration curves for common acids and bases.

 Built-in features to easily display accurate amperometric and

turbidity measurements.
