EMERSON 142U2D301CACAB165240 Servo motor
Product Dimensions:
The Rosemount 3051S is an industry-leading line of smart pressure transmitters known for its exceptional performance, reliability, and innovative SuperModule™ platform.
The specific model number 142U2D301CACAB165240 is a highly customized configuration, which can be partially deciphered as follows:
| Code Segment | Description (Likely Meaning) |
| 142U | Indicates the specific Transmitter Type/Platform. This likely points to the 3051S Scalable Coplanar Platform or a similar high-performance variant. |
| 2D | Indicates the Pressure Type, most commonly a Differential Pressure (DP) Transmitter used for flow or level measurement. |
| 3 | Indicates the Pressure Range/Range Limit (e.g., a specific pressure span). |
| 01 | Indicates the Output Signal Type, usually 4-20 mA with HART Protocol. |
| CACAB | Represents a combination of Process Connection (e.g., Coplanar Flange), Housing Material, and Conduit Entry. |
| 165 | Likely a Specific Calibration Range or Configuration Code. |
| 240 | May denote Diaphragm Material (e.g., Tantalum, Gold-plated Stainless Steel) and Fill Fluid. |
-
Function: Measures the difference between two pressure points (Differential Pressure) or the absolute/gage pressure of gases, vapors, or liquids in a process line.
-
Technology: Utilizes advanced capacitance sensor technology, housed in the patented SuperModule, to ensure high stability and accuracy.

✨ Product Advantages (Key Benefits)
-
Superior Performance: Offers market-leading accuracy and exceptional long-term stability, reducing maintenance and recalibration costs.
-
Scalable Platform: The 3051S architecture allows for easy upgrades to advanced features (like WirelessHART or safety functions) without replacing the entire unit.
-
Coplanar Design: The standard Coplanar flange simplifies installation and offers flexibility for connecting to various manifolds, including traditional, in-line, and flow-integrated solutions.
-
Advanced Diagnostics: Includes optional Power Advisory Diagnostics to monitor electrical health and detect issues before they impact process control.
-
MultiVariable Capability (Optional): Can simultaneously measure DP, Static Pressure, and Process Temperature.
⚠️ Cautions and Considerations
-
Configuration Check: Always verify the specific Wetted Materials (Diaphragm, Fill Fluid) against the process fluid’s compatibility to prevent corrosion or failure.
-
Pressure Rating: Ensure the selected Pressure Range and Overpressure Limit meet or exceed the maximum process conditions to avoid sensor damage.
-
HART Protocol: Effective use requires a HART communicator or control system capable of interpreting the digital signal for configuration and advanced diagnostics.
-
Installation Orientation: For DP measurements, the transmitter should be installed correctly (e.g., equal elevations for level applications) to avoid hydrostatic head errors.
-
Calibration: Though highly stable, regular checks of the zero point and span are recommended per industry standards.
🎯 Product Applications
The Rosemount 3051S DP Transmitter is a workhorse in demanding process industries:
-
Flow Measurement: Used with primary elements (like Orifice Plates, Venturis, or Pitot Tubes) to measure fluid flow rate by detecting the pressure drop.
-
Level Measurement: Used on tanks and vessels to measure the hydrostatic pressure of the fluid, determining the level.
-
Interface Level Measurement: Used to determine the level between two immiscible liquids.
-
Pressure Monitoring: Used for critical system pressure control and monitoring in pipelines, reactors, and headers.
-
Industry Focus: Widely used in Oil & Gas, Chemicals, Refining, Power Generation, and Pharmaceutical sectors due to its high accuracy and reliability.
