🖹 Description
This is a Rosemount 3051 series pressure transmitter — a modern, high-performance version of the previous 1151 you showed.
The pressure transmitter model 3051 L3 from the Emerson Rosemount series is a modern, high-performance smart differential pressure transmitter designed for advanced industrial process control. It represents a significant evolution from earlier models like the 1151, offering improved accuracy, digital communication, and enhanced diagnostics.
What It Is
The Rosemount 3051 L3 is a smart differential pressure transmitter capable of measuring pressure or pressure difference (ΔP) and converting it into a standardized 4–20 mA signal, often combined with digital HART communication. This allows seamless integration with PLC and DCS systems.
What It Does
This device performs precise and continuous measurement of:
- Differential pressure (ΔP)
- Gauge pressure
- Derived variables such as flow and level
It provides real-time data to control systems, enabling accurate and automated process control.
Design and Components
The transmitter features a robust and modern industrial design:
- Blue housing: Contains smart electronics with digital communication capabilities
- Sensor/manifold block: Connects to high and low pressure sides (HP/LP)
- Flanged mounting: Ensures secure installation in process lines
Key Advantages Over Older Models
Compared to traditional transmitters (like the Rosemount 1151), the 3051 offers:
- Higher measurement accuracy
- Digital communication via HART protocol
- Remote calibration and configuration
- Built-in diagnostics and self-monitoring
How It Works
The operation is based on advanced sensing technology:
- Pressure is applied to the sensor
- The sensor detects deformation with high precision
- Electronics convert this into an electrical signal
- Output is transmitted as:
- 4–20 mA (analog signal)
- Digital data (HART communication)
Example Application (Flow Measurement)
- Increased differential pressure → increased flow
- Transmitter outputs higher current (mA)
- Control system calculates and regulates flow
Typical Applications
The Rosemount 3051 L3 is widely used in:
- Oil & gas industry
- Chemical processing plants
- Power generation facilities
- Water treatment systems
- Advanced industrial automation
