Emerson Launches Rosemount 708 Wireless Sound Transmitter

Introduction: Emerson Process Management introduces the Rosemount® 708 wireless sonic transducer, which integrates temperature measurements with acoustic “listening” capabilities to provide detailed information on the condition of the trap and relief valve, enabling the process The energy consumption of the factory and its impact on the environment are greatly reduced.

Emerson Process Management introduces the Rosemount® 708 wireless sound sensor. This new transmitter is an important part of Emerson's "smart energy plan". It integrates Emerson's unparalleled industrial energy expertise and advanced technology to help users save energy and reduce emissions. The Rosemount 708 Wireless Acoustic Transmitter integrates temperature measurements with acoustic “listening” capabilities to provide detailed information on the condition of the trap and relief valve, significantly reducing energy consumption and the environmental impact of the process plant.

Steam production plants are an important drain on the operation of process plants. During steam trap failure, 20% of the steam is typically lost in the boiler. The Rosemount 708 Wireless Sound Transmitter provides accurate measurement and continuous monitoring of the trap without manual intervention, allowing a dramatic reduction in the number of trap failures and fuel costs by 10-20% per year.

Pressure relief valve is another key component of the factory. Regular manual monitoring of the relief valve pressure relief does not indicate when or why the pressure relief occurred. This increases the probability of safety, management, or environmental accidents. The Rosemount 708 wireless sonic transmitter can alert the operator by alerting the pressure relief valve within a minimum of one second after the valve is opened. The time-stamped alarm device can be compared with process conditions or environmental reports to help identify the source of pressure relief, so that precautionary measures can be taken to reduce future emissions.

Based on Emerson's previous experience with smart wireless field instruments, the new transmitter provides operators with instant and intuitive information on all key traps and pressure relief valves through a non-intrusive wireless HART monitoring system. The system can be monitored throughout the plant (even if it is remote or difficult to reach), with data reliability of more than 99%. Real-time alarm devices can identify areas that require attention, so operators can take appropriate actions based on these operational information.

The Rosemount 708 Wireless Acoustic Sensing Transmitter enables quick and easy implementation and minimal routine maintenance, leveraging existing plant, equipment, and experience in the process plant. The sturdy transmitter has a 10-year battery life and is designed as a type-safe polymer housing that resists wind erosion and chemicals.
