Product Description

Product Description

Rosemount 3051CD PressureTransmitter

The Rosemount 3051CD Transmitter is a state-of-the-art smart pressure transmitter designed to measure absolute pressure, gauge pressure, and differential pressure in industrial process applications. It converts the physical pressure signals into standardized electrical signals (such as 4-20 mA DC or digital signals via communication protocols like HART, FOUNDATION Fieldbus, or PROFIBUS) that can be easily transmitted to control systems, allowing for real-time monitoring, control, and optimization of process variables.
At its core, the transmitter's primary function is to provide accurate and stable pressure measurements even in harsh and dynamic process conditions. Whether it is monitoring the pressure of a high-temperature chemical reactor, the differential pressure across a filter in a water treatment plant, or the absolute pressure in a steam boiler, the Rosemount 3051CD is engineered to deliver consistent performance, ensuring that process parameters remain within the desired range and enabling timely intervention in case of deviations.
Emerson's design philosophy for the Rosemount 3051CD Transmitter revolves around three key pillars: reliability, accuracy, and user-friendliness. These principles are embedded in every aspect of the transmitter's design, from the selection of high-quality materials to the integration of advanced software algorithms, ensuring that it meets the evolving needs of industrial users and operates seamlessly in even the most challenging environments.

1. Core Technologies and Working Principle

1.1 Capacitance-Based Sensor Technology
At the heart of the Rosemount 3051CD Transmitter lies its advanced capacitance-based sensor technology, which is responsible for converting the physical pressure signal into an electrical signal that can be processed and transmitted.
The capacitance-based sensor consists of two parallel plates: a fixed plate and a movable diaphragm. The movable diaphragm is in direct contact with the process fluid or gas, and when pressure is applied, it deflects towards the fixed plate. This deflection changes the distance between the two plates, thereby altering the capacitance of the sensor (since capacitance is inversely proportional to the distance between the plates). The change in capacitance is then measured by the transmitter's electronic circuitry, which converts it into a proportional electrical signal.
One of the key advantages of the capacitance-based sensor is its high sensitivity, which allows it to detect even small changes in pressure. Additionally, the sensor has a low temperature coefficient, meaning that its performance is relatively unaffected by changes in temperature. 
1.2 Signal Processing and Communication Protocols
Once the capacitance-based sensor converts the pressure signal into an electrical signal, the Rosemount 3051CD's electronic circuitry processes this signal to ensure accuracy and reliability. The signal processing unit includes a preamplifier that amplifies the weak electrical signal from the sensor, followed by an analog-to-digital converter (ADC) that converts the analog signal into a digital signal. The digital signal is then processed by a microprocessor, which applies various correction algorithms, such as temperature compensation, linearization, and zero adjustment, to eliminate errors and improve the accuracy of the measurement.
After processing, the digital signal is converted back into an analog signal (4-20 mA DC) for transmission to the control system, or it is transmitted digitally via one of the supported communication protocols. The Rosemount 3051CD supports a range of industry-standard communication protocols, including HART (Highway Addressable Remote Transducer), FOUNDATION Fieldbus, and PROFIBUS.

2. Key Features

The Rosemount 3051CD Transmitter is packed with a wide range of features that make it a highly versatile and efficient pressure measurement solution. These features are designed to address the specific needs of industrial users, enhancing the transmitter's performance, reliability, and usability. Some of the key features of the Rosemount 3051CD include:
Wide Measurement Range: The transmitter offers a wide range of measurement ranges, covering absolute pressure from 0 to 100 psi (0 to 6.89 bar) up to 0 to 10,000 psi (0 to 689.5 bar), gauge pressure from 0 to 100 psi (0 to 6.89 bar) up to 0 to 10,000 psi (0 to 689.5 bar), and differential pressure from 0 to 0.5 inH2O (0 to 0.124 kPa) up to 0 to 1000 psi (0 to 68.95 bar). 
High Accuracy and Stability: As mentioned earlier, the Rosemount 3051CD achieves an accuracy of up to ±0.04% of span, ensuring precise and reliable measurements. 
Temperature and Pressure Compensation: The transmitter is equipped with advanced temperature and pressure compensation functions that correct for errors caused by changes in ambient temperature and process pressure.
Diagnostic Capabilities: The Rosemount 3051CD features comprehensive diagnostic capabilities that allow for the early detection of potential issues, such as sensor drift, wiring faults, and process anomalies. The transmitter can generate diagnostic alerts and provide detailed information about the nature of the problem, enabling maintenance personnel to take timely action and prevent unexpected failures.
Hazardous Area Certification: The transmitter is certified for use in hazardous areas, including Class I, Division 1 and 2, Groups A, B, C, D; Class II, Division 1 and 2, Groups E, F, G; and Class III, Division 1 and 2.
Modular Design: The Rosemount 3051CD features a modular design that allows for easy customization and maintenance. The transmitter consists of separate modules, such as the sensor module, electronic module, and housing, which can be replaced individually if needed.
Low Power Consumption: The transmitter is designed to consume low power, making it suitable for use in applications where power is limited, such as remote locations or battery-powered systems. The low power consumption also helps to reduce operating costs and minimize the environmental impact of the instrument.
