Rosemount 708 Wireless Acoustic Transmitter

Ultrasonic acoustic event detection

 Reliably detects and transmits information about acoustic events such as leaks

 Transmitter output includes acoustic level (0 to 255 counts) and temperature

(–40 to 260 °C)

 Transmitter communicates process variable and status information via the wireless

network for integration into existing host systems

Monitor steam traps

 Steam Trap Monitoring application provides critical, real-time information on the

condition of your monitored steam trap population

 Real-time monitoring provides instantaneous feedback for system maintenance and

optimization

Monitor pressure relief valves or pressure safety

Rosemount 708

valves

 Turbulence generated by a leaky valve can be detected using the acoustic transmitter

 Notification when release is occurring and when the release has stopped

 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

high vibration level (10–60 Hz 0.21 mm displacement peak
amplitude/60–2000 Hz 3 g).

Temperature limits

Ambient limit: –40 to 85 °C (–40 °F to 185 °F)
Storage limit: –40 to 85 °C (–40 °F to 185 °F)
Heat from the process is transferred to the transmitter housing.
If the process temperature is high, the ambient temperature will
need to be lower to account for heat transferred to the
transmitter housing. (see Table 3 on page 7)

harmful interference. This device must accept any interference
received, including interference that may cause undesired
operation. This device must be installed to ensure a minimum
antenna separation distance of 20 cm from all persons.

Ordinary Location Certification

As standard, the transmitter has been examined and tested to
determine that the design meets the basic electrical,
mechanical, and fire protection requirements by a nationally
recognized test laboratory (NRTL) as accredited by the Federal
Occupational Safety and Health Administration (OSHA).
