Revolutionizing Process Temperature Monitoring

The Rosemount 248 Wireless Temperature Transmitter is a cutting-edge solution designed for reliable, cost-effective, and flexible temperature measurement across a vast array of industrial processes. Operating on the robust WirelessHART® standard (IEC 62591), it eliminates the significant expense and complexity associated with traditional wired installations. This self-organizing, mesh-networked device seamlessly integrates into existing WirelessHART networks or forms the foundation of new ones, transmitting critical temperature data from previously difficult or uneconomical locations. Engineered for demanding environments, the 248 supports a wide range of industry-standard temperature sensors (RTDs and Thermocouples), providing high-accuracy measurements critical for process control, safety, and efficiency. Its core mission is to deliver essential process insights without the constraints of wires, enabling enhanced monitoring, improved decision-making, and significant operational savings.

Unmatched Flexibility and Advanced Diagnostics

Unmatched Flexibility and Advanced Diagnostics

A defining strength of the Rosemount 248 is its exceptional versatility. It features dual-input capability, allowing connection to two independent temperature sensors simultaneously. This enables powerful applications such as monitoring both a primary process temperature and a crucial equipment bearing or motor winding temperature for condition monitoring, or providing redundant measurement points for critical processes. Furthermore, the 248 incorporates Emerson's innovative Rosemount X-well™ Technology. 

 This unique feature allows for non-invasive surface temperature measurement using a specialized integral sensor, eliminating the need for a thermowell or process penetration. This drastically simplifies installation on pipes, tanks, or vessels, reduces potential leak points, and minimizes installation costs and downtime. Combined with WirelessHART diagnostics and HART 7 capability, the 248 provides unprecedented insight into both the process condition and the health of the transmitter and connected sensors, facilitating predictive maintenance and reducing unexpected failures.

Robust Reliability and Simplified Operations

Built to endure harsh industrial environments, the Rosemount 248 transmitter sets a high bar for reliability and longevity. Its robust construction ensures resilience against extreme temperatures, high humidity, corrosive atmospheres, and severe vibration, meeting stringent standards like SIL 2 for functional safety and IP66/Type 4X ingress protection. A key operational advantage is its exceptional battery life, exceeding 10 years under typical operating conditions. This longevity is achieved through ultra-low-power electronics and sophisticated power management, virtually eliminating the maintenance burden and cost associated with frequent battery replacements. Installation and commissioning are remarkably straightforward. The compact, lightweight design allows for quick mounting directly at the measurement point using standard pipe clamps or surface mounts. 

Driving Value through Enhanced Connectivity and Insight

The Rosemount 248 delivers substantial economic and operational value by seamlessly integrating temperature data into the modern industrial ecosystem. By eliminating conduit, cable trays, and associated installation labor, it offers up to 60% reduction in installation costs compared to wired solutions. The rich diagnostic information accessible remotely minimizes the need for physical inspections in potentially hazardous or hard-to-reach areas, enhancing personnel safety. Integration with control systems (via a WirelessHART Gateway) and plant data historians enables real-time process visibility and control, while connectivity to asset performance management platforms unlocks powerful analytics for optimizing process efficiency, improving product quality, and reducing energy consumption. The 248 is a cornerstone technology for implementing predictive maintenance strategies, identifying potential equipment issues like motor bearing failures or heat exchanger fouling before they cause unplanned downtime.
