Description

ROSEMOUNT 1056-03-21-32-AN Multi-parameter Analyzer

Product Dimensions：

The Rosemount 1056-03-21-32-AN is a high-performance, multi-parameter liquid analytical transmitter part of the Model 1056 series. It is globally recognized for its versatility, allowing for the simultaneous measurement of up to two liquid analytical parameters using a single instrument.

Product Detailed Description

The 1056-03-21-32-AN is a line-powered analyzer designed to interface with a wide range of Rosemount liquid sensors. The specific model string defines a precise hardware configuration, including the input card selections (e.g., pH/ORP, Conductivity), communication protocol, and housing style.

The instrument features a large, high-contrast LCD display that can display multi-language readouts and simultaneous loops, making it an excellent choice for complex industrial water treatment and process monitoring.

Technical Parameters (Model Code Breakdown)

Based on the Rosemount 1056 ordering matrix, here is the technical breakdown of the specific configuration 1056-03-21-32-AN:

General Specifications:

• Enclosure: NEMA 4X / IP66 rugged polycarbonate casing.
• Ambient Temperature: 0 to 50°C (32 to 122°F).
• Display: Monochrome, graphic LCD with backlighting.
• Relays: Four independent Alarm Relays (SPDT).

Product Advantages

• Dual Parameter Capability: Reduces installation costs and panel space by allowing a single analyzer to process both a Conductivity sensor and a pH sensor simultaneously.
• Easy-to-Read Display: The large font and user-customizable display can show process variables, temperature, and diagnostics for both channels at a glance.
• Quick Configuration: Features automated sensor recognition for quick startups. The intuitive menu programming requires no reference manual for routine calibration.
• Robust Diagnostics: Continuously monitors sensor health, alerting operators to glass breakage (for pH) or calibration faults before they cause process issues.

Important Considerations (Precautions)

• Pre-amplifier Requirement: For the pH channel (Code 32), if the sensor is located more than 15 feet (approx. 4.5 meters) away from the transmitter, an external preamplifier or a smart sensor with an internal preamplifier is required to prevent signal degradation.
• Cable Separation: Keep sensor cabling isolated from high-voltage power lines and Variable Frequency Drives (VFDs) to prevent electromagnetic interference from skewing analytical readings.
• Calibration Routines: Always calibrate the pH sensor using fresh, certified buffer solutions (pH 4, 7, or 10), and ensure the conductivity sensor constant (C) matches the configuration settings.
• Enclosure Seal: Ensure the front panel screws are properly tightened to retain the NEMA 4X weatherproofing seal, especially in outdoor or washdown environments.

Product Applications

This specific combination (Conductivity + pH) is highly utilized across diverse industries:

• Boiler Feedwater Protection: Monitoring high-purity water conductivity to prevent scaling while checking pH to mitigate acid-driven pipeline corrosion.
• Industrial Wastewater Treatment: Checking pH compliance before discharge and monitoring total dissolved solids (TDS) via conductivity.
• Cooling Towers: Managing chemical dosing loops based on pH and controlling blowdown cycles based on conductivity limits.
• Reverse Osmosis (RO) Systems: Evaluating membrane efficiency by measuring conductivity before and after filtration, alongside pH tracking.
