1056-03-20-38-AN Rosemount Pressure Temperature Transmitter -40 To 150 °C
1056-03-20-38-AN Description
The Rosemount 1056-03-20-38-AN is a high-performance, single-point thermocouple (TC) or resistance temperature detector (RTD) input module designed for integration with Rosemount’s 3400-series Transmitters (such as the 3420 Field Indicator) and 3051 Pressure Transmitters. It functions as a remote temperature sensor interface, enabling these primary transmitters to provide a temperature reading alongside their main process variable (e.g., pressure, level, or flow). This configuration creates a cost-effective, multivariable measurement point, reducing installation hardware and simplifying system architecture.
1056-03-20-38-AN Features
-
Multivariable Measurement: Enables a single pressure transmitter to deliver a second, fully isolated process variable (temperature), eliminating the need for a separate temperature transmitter and associated wiring.
-
Universal Input: Supports a wide range of temperature sensor types, including common thermocouples (Types J, K, T, E, N, R, S, B) and RTDs (2-wire, 3-wire, or 4-wire Pt100, Pt1000, Cu10, Ni120), offering exceptional application flexibility.
-
High Accuracy & Stability: Leverages Rosemount's advanced measurement technology and the transmitter's electronics to provide precise, stable, and reliable temperature readings suitable for demanding process control and monitoring.
-
Digital Integration: Communication is handled digitally via a dedicated interface within the transmitter housing, ensuring robust signal integrity, superior noise immunity, and simplified configuration compared to traditional analog loops.
-
Easy Configuration: The temperature input type, range, and other parameters are easily configured using the familiar Rosemount AMS Device Manager, HART handheld communicator, or the transmitter's local display interface.
1056-03-20-38-AN Material & Primary Applications
-
-
Process Connection: Typically ½-inch NPT female threads, constructed from 316L stainless steel for standard process compatibility and corrosion resistance.
-
Sensor Connection: Terminal block and internal electronics designed for industrial environments.
-
Gasket: Integrated graphite-filled PTFE gasket ensures a reliable seal.
-
Primary Applications: Used to add temperature measurement to a primary process point, essential for:
-
Density Compensation: Accurately calculating mass flow or compensated level from pressure-based measurements.
-
Process Monitoring & Control: Providing local temperature data for heat exchangers, reactors, storage tanks, and pipelines.
-
Condition Monitoring: Measuring temperature for equipment health and process efficiency diagnostics.
-
System Simplification: Reducing I/O count, wiring, and documentation in DCS/PLC systems by consolidating measurements.
