Rosemount 708 Series Wireless Acoustic Transmitter Level Transmitter
Product Description
Rosemount™ 708 Wireless Acoustic Transmitter
Featuring ultrasonic acoustic event detection that mounts externally, the Rosemount™ 708 Wireless Acoustic Transmitter offers a fast, cost effective installation. This device allows visibility into steam traps and pressure relieve valves (PRVs) by accurately communicating acoustic level and temperature data as well as device data, event status and leak detection via the WirelessHART® network. The Steam Trap Monitor software (optional) provides real-time information about steam trap conditions, energy usage and emissions.Features
- Detects and transmits acoustic level and temperature data to increase visibility and monitor steam traps and PRV's
- Directly mounts to process piping without cutting or changing pipe configurations for flexible, simple installation
- Steam Trap Monitoring software (optional) provides critical, real-time information on steam trap conditions
- Rugged and robust transmitter design ensures consistent performance in harsh environments
- WirelessHART® technology is secure, cost-effective and delivers >99% data reliability
- WirelessHART® network easily integrates into host systems, data historians or energy management software
- Easy, intuitive and non-intrusive installation enables a quick method to automate without the cost of wiring
- SmartPower™ solutions provide up to 10-year maintenance-free operation and replacement without transmitter removal

The Rosemount 708 Wireless Acoustic Transmitter is designed for use in numerous applications including pressure relief valve monitoring and steam trap monitoring. This document will outline the theory of operation for the transmitter. The Rosemount 708 Wireless Acoustic Transmitter is a WirelessHART, battery powered transmitter. The transmitter is a multi-variable device with two sensors:
a thermocouple and an ultrasonic sensor.
The Rosemount 708 Wireless Acoustic Transmitter provides constant visibility and accurate measurement of critical steam traps without the effort of a manual inspection, enabling plants to dramatically decrease steam trap failures and reduce fuel costs by 10% to 20% each year, according to Emerson Process Management. Steam production is a significant operating expense for processing plants. About 20% of the steam leaving a boiler is lost through failing steam traps. Most plants test traps once per year with a visual inspection or hand-held device designed to measure temperature or ultrasonic noise caused by a blockage, but these methods can be imprecise and expensive. Annual testing means that leaks go undetected for months. Using the Rosemount 708, process plants can continually monitor critical steam traps and address failures before they happen. By combining temperature measurement with acoustic listening, the Rosemount 708 provides continuous visibility to steam trap state (normal, stuck closed, or stuck open.)

Ultrasonic acoustic event detection
1.Reliably detects and transmits information about acoustic events such as leaks
2.Transmitter output includes acoustic level (0 to 255 counts) and temperature (-40 to 260 °C)
3.Transmitter communicates process variable and status information via the wireless network for integration into existing host systems
Monitor steam traps
1.Steam Trap Monitoring application provides critical, real-time information on the condition of your monitored steam trap population
2.Real-time monitoring provides instantaneous feedback for system maintenance and optimization
Monitor pressure relief valves or pressure safety valves
1.Turbulence generated by a leaky valve can be detected using the acoustic transmitter
2.Notification when release is occurring and when the release has stopped
3.Emerson Wireless network provides timestamped information to the host Automated data enables reporting of a tamper-proof data log
Mounting flexibility
The wireless acoustic transmitter can be directly mounted to process piping without cutting pipes or changing pipe configurations allowing for a flexible, easy installation.
Reliable transmitter performance
The rugged and robust design of the transmitter ensures reliable performance in harsh environments.
