Product Description

Rosemount 708 Wireless Acoustic Transmitter 

The Rosemount 708 Wireless Acoustic Transmitter is a cutting-edge solution designed to deliver real-time acoustic monitoring for industrial processes, enabling proactive maintenance and operational efficiency. Engineered by Emerson, a leader in industrial automation technology, the Rosemount 708 leverages wireless communication and advanced sensor technology to detect and analyze high-frequency acoustic signals, providing critical insights into equipment health and process integrity. This transmitter is ideal for applications requiring early detection of anomalies such as leaks, cavitation, blockages, or mechanical wear, making it an indispensable tool for industries like oil and gas, chemical processing, power generation, and water/wastewater management.

Key Features and Capabilities At the heart of the Rosemount 708 is its high-performance piezoelectric sensor, which captures acoustic emissions across a wide frequency range. This sensor is optimized to detect subtle changes in sound patterns, ensuring sensitivity to even the smallest process deviations. The transmitter's wireless design eliminates the need for complex cabling, reducing installation costs and time while enabling deployment in remote or hazardous locations. Utilizing the WirelessHART® protocol, the 708 ensures secure, reliable data transmission in challenging industrial environments, integrating seamlessly with existing asset management systems and control networks.

The device operates on a low-power architecture, powered by a long-life lithium battery that supports uninterrupted monitoring for up to 10 years, depending on usage conditions. This extended battery life minimizes maintenance requirements, making the 708 a cost-effective alternative to wired acoustic monitoring systems. Additionally, its rugged construction meets global explosion-proof and ingress protection standards (e.g., ATEX, IECEx, NEMA 4X), ensuring durability in harsh outdoor or corrosive environments.

Advanced Diagnostics and Predictive Maintenance The Rosemount 708 goes beyond basic signal detection by providing intelligent diagnostics and trend analysis. Its onboard signal processing algorithms convert raw acoustic data into actionable metrics, such as amplitude levels, frequency spectra, and noise energy patterns. These metrics can be transmitted to centralized systems like Emerson's Plantweb™ digital ecosystem or third-party analytics platforms for further analysis. By correlating acoustic data with process variables, operators can identify root causes of issues, prioritize maintenance tasks, and reduce unplanned downtime. For example, in steam trap monitoring, the 708 can distinguish between normal operation and failure modes like blow-through or blockage, enabling timely interventions before failures escalate.

Versatile Applications The flexibility of the Rosemount 708 makes it suitable for a wide range of applications:

Leak Detection: Identifies gas or liquid leaks in pipelines, vessels, or valves by sensing turbulent flow-induced noise.
Cavitation Monitoring: Detects early signs of cavitation in pumps and compressors, preventing costly equipment damage.
Mechanical Fault Diagnosis: Analyzes acoustic signatures to identify bearing wear, gear failures, or misalignments in rotating machinery.
Valve Integrity Assessment: Monitors acoustic emissions to assess valve leakage or actuator performance.
Process Anomaly Detection: Flags abnormal acoustic patterns during batch processes or reactor operations, enhancing safety and quality.
Integration and Scalability The Rosemount 708's compatibility with WirelessHART networks allows easy integration into both new and existing facilities without retrofitting infrastructure. Multiple transmitters can operate within a single mesh network, automatically optimizing communication paths for reliability. Data is accessible via Emerson's AMS Device Manager or other predictive maintenance software, enabling visualization of trends, alarms, and historical records. For enhanced scalability, the transmitter supports cloud connectivity through gateways, facilitating remote monitoring and decision-making for global operations.
