The Coplanar 3051C Pressure Transmitter – Compact Design for Flexible Installation

The coplanar design is the defining feature of the 3051C. Unlike traditional transmitters, the coplanar platform allows the process connections, manifold, and transmitter body to align on the same plane. This configuration simplifies installation, reduces the need for complex fittings, and minimizes potential leak points. For operators working in confined plant areas or applications where direct mounting is essential, this design proves invaluable. It ensures that accurate pressure measurements can be achieved without requiring excessive piping or additional space.

One of the most significant advantages of the Rosemount 3051C Coplanar transmitter is its performance stability. Offering accuracy up to 0.04 percent of span and long-term stability for up to 10 years, it ensures consistent performance throughout its operational life. The reduced need for recalibration not only saves time and labor but also lowers overall maintenance costs. In industries where downtime is expensive, this stability directly contributes to improved operational efficiency and profitability.

The 3051C Coplanar transmitter also supports wide rangedown capabilities, often up to 150:1. This means that one device can handle a broad range of applications, from low-pressure monitoring to higher process pressures. For companies managing large inventories, this versatility reduces the number of spare parts required and simplifies procurement. This directly translates into lower inventory costs and greater flexibility for engineers and procurement managers.

Connectivity and usability are equally important in modern industrial settings. The Rosemount 3051C offers HART protocol as a standard option, making it easy to integrate into distributed control systems and asset management platforms. Many models also feature optional LCD displays, giving operators immediate visibility into real-time process conditions. The local display simplifies commissioning, troubleshooting, and ongoing monitoring, especially in areas where control room access may be limited. Some advanced versions are also equipped with Bluetooth connectivity, enabling configuration and diagnostics without opening the housing, further improving safety and efficiency.

Another notable advantage of the 3051C is its compatibility with Emerson’s manifold solutions. When combined with a Rosemount 305 integral manifold, the transmitter becomes even easier to install and maintain. The manifold allows for isolation, equalization, and venting of the transmitter without additional external piping. This integrated approach not only reduces installation time but also minimizes the chance of leaks or errors, ensuring safer and more reliable operation.

Diagnostics and digital integration further enhance the value of the 3051C Coplanar transmitter. With advanced features such as Power Advisory diagnostics, the transmitter can alert operators to potential issues before they result in costly failures. Integration with Emerson’s PlantWeb ecosystem enables predictive maintenance and provides valuable insights into process health, helping facilities to optimize performance and reduce downtime.

Durability is another strength of the 3051C. Constructed from high-quality materials such as stainless steel and Hastelloy, and offered with various housing options including aluminum and stainless steel, the transmitter is built to withstand harsh environments. Whether exposed to corrosive chemicals, high humidity, or extreme temperatures, the device is engineered to deliver reliable performance over the long term.
