The Rosemount 3051 series is a versatile line of industrial transmitters designed for various pressure measurement needs. Understanding the model suffixes is essential for correct selection and system design.

01 Accuracy Classification
The Rosemount 3051 series transmitters are categorized by their reference accuracy levels to meet different process requirements.
| Accuracy Level | Model Series | Recommended Use |
| 0.02% | 3051S | Critical high-precision applications |
| 0.04% | 3051C, 3051T | High-performance process control |
| 0.06% | 3051D, 3051G | Standard industrial monitoring |
Transmitters such as the 3051C are chosen when high-precision operating conditions are required, while the 3051D is commonly used for standard designs where 0.075% accuracy is the typical baseline.
02 Structural Forms
The physical construction of the transmitter determines how it connects to the process piping.
-
Coplanar Form (3051C, 3051D): These models use a coplanar platform for integrated manifold mounting.
-
Direct-Connect Form (3051T, 3051G): These models are designed for direct threaded or flanged connections.
03 Model Suffix Meanings and Applications
The alphabetic suffixes in the Rosemount 3051 series transmitters represent the specific type of pressure being measured.
| Akhiran Model | Meaning | Jenis Pengukuran |
| GP | Tekanan Tolok | Standard relative pressure measurement |
| TG | Tekanan Tolok | Direct-connect relative pressure measurement |
| TA | Absolute Pressure | Measurement relative to a full vacuum |
| CD | Differential Pressure | Coplanar high-precision differential measurement |
| CG | Tekanan Tolok | Coplanar gauge pressure (often for small ranges) |
| DP | Differential Pressure | Standard differential pressure measurement |
| DG | Tekanan Tolok | Standard gauge pressure (often for small ranges) |
04 Series Derivations
The 3051C and 3051D series serve as the foundation for several specialized derivative models.
-
3051C Derivatives: Includes the 3051CA for absolute pressure, 3051CG for small-range gauge pressure, and 3051CD for differential pressure.
-
3051D Derivatives: Includes the 3051DG for small-range gauge pressure and 3051DP for differential pressure.
