Valve switching device with Rosemount 8800 Vortex Flowmeter and 3100 Smart Ultrasonic Level Transmitter

The Emerson Rosemount 3100 Series represents a robust line of pressure transmitters designed to deliver dependable and accurate measurement for a wide array of industrial applications. Engineered with a focus on core functionality, ease of use, and durability, this series provides a cost-effective solution without compromising on the quality and reliability synonymous with the Rosemount name. It is ideally suited for general-purpose pressure, level, and flow measurements in industries such as water and wastewater, chemical processing, power generation, oil and gas, and manufacturing.

At the heart of the Rosemount 3100 Series' performance is its advanced sensor technology. Depending on the specific model, it utilizes a proven silicon or ceramic capacitor sensor cell. These technologies provide a stable and accurate measurement foundation, effectively converting process pressure into a precise electrical signal. The transmitters are designed to maintain their calibration over extended periods, ensuring consistent performance and reducing the need for frequent maintenance. This long-term stability is a key factor in lowering the total cost of ownership, as it minimizes downtime and operational interruptions.

The series is built to thrive in challenging industrial environments. Its rugged housing is rated for demanding conditions, offering excellent resistance to vibration, moisture, and electromagnetic interference. A standout feature is the intuitive local operator interface (LOI), which allows for easy configuration and troubleshooting without the need to open the electronics housing. This maintains the integrity of the device's weatherproof and explosion-proof certifications, such as ATEX and IECEx, making it safe for use in hazardous areas. The availability of a wide range of process connections and diaphragm materials ensures compatibility with various media, including corrosive and viscous fluids.

Simplicity in integration is another hallmark of the Rosemount 3100. It supports the ubiquitous 4-20 mA analog output with HART® communication protocol. This allows for seamless connection to existing control systems while enabling advanced digital capabilities. Using a HART communicator or asset management software like Emerson's AMS Device Manager, users can remotely access detailed device information, perform diagnostics, and re-range the transmitter, all without disrupting the process loop. This capability streamlines commissioning and maintenance procedures.

In application, the versatility of the 3100 Series shines. It accurately measures gauge, absolute, and differential pressure, making it suitable for everything from simple tank level monitoring to more complex flow calculation tasks via differential pressure across an orifice plate. Its reliable performance in the presence of common challenges like temperature fluctuations and process noise makes it a trusted workhorse in countless plants worldwide.

In summary, the Emerson Rosemount 3100 Series Pressure Transmitter offers a compelling blend of essential measurement integrity, rugged construction, and user-friendly operation. It embodies the core principles of reliability and value, providing a trusted solution for engineers who require a durable and accurate transmitter for their most common—and critical—process measurements. By delivering dependable data day after day, it forms a fundamental layer of intelligence for modern industrial automation and control systems.
