Real-time Visibility to PRV Conditions

 Ultrasonic acoustic event detection

Manual rounds inspecting for displaced “socks” off Pressure Relief Valves are imprecise and expensive, putting you at risk for regulatory fines. And, for valves without a sock, you may not ever know a release occurred. Using the Rosemount 708 Wireless Acoustic Transmitter, you can monitor your critical PRVs every minute of every day to address releases as they happen and minimize fines and environmental concerns. Knowing that you’ve had a release, you can address underlying conditions before they lead to a more dangerous situation. Industry-leading acoustic “listening” gives you unparalleled visibility to PRVs. With update rates as fast as one second, the system alerts operators when a valve has opened. The Rosemount 708 easily integrates into any control system.

 Smart wireless system

Gain visibility to all your pressure relief valves, no matter where they are located. Emerson’s Smart Wireless approach allows you to monitor PRVs throughout your plant, even in remote and hard-to-reach locations, with greater than 99% data reliability. The Rosemount 708 works with your existing WirelessHART network. If your plant does not have a wireless network, you can easily start small with a Smart Wireless Gateway and any number of transmitters.

 Time stamped, real-time alerts

Relying on visual inspections of pressure relief valves leaves you susceptible to human error as well as false alarms, such as when the wind blows a sock off a PRV. The Rosemount 708 notifies you with real-time alerts, so that you know immediately when a PRV opens. This real-time notification enables you to handle issues as they arise and minimize regulatory concerns. Each alert is time stamped and integrated into the data historian using tamper-proof OPC data, so that you can compare against process conditions or environmental reporting to identify the root cause of a release.
Fast and Easy to Install and Maintain

Easy, fast, flexible to install

Installing new instrumentation can be time consuming and tricky, especially if it involves cutting into pipes or modifying valves and training your staff on unfamiliar procedures. With the Rosemount 708, you won’t need to worry about adding complexity or workload. The system is easy, fast and flexible to install; no training required. The devices are non-intrusive and mounted using supplied stainless steel mounting bands, so you won’t need to cut into your pipes. The small, lightweight engineered polymer housing means that you can place it anywhere, even in tight spots, locations with harsh environmental conditions or hazardous areas.

Set and forget

Monitoring of PRVs takes your staff away from other responsibilities. The Rosemount 708 is a “set and forget” solution, relieving you of the burden of regular monitoring with the confidence that you have the information you need. With a 10-year battery life and engineered polymer housing that is intrinsically safe, weather proof and chemically resistant, the Rosemount 708 rarely needs attention, letting you focus on other responsibilities.

Intrinsically safe power module

Replacing power modules in hazardous locations can be a hassle, causing extra paperwork and expense. The Rosemount 708 has an intrinsically safe power module that’s easy to maintain. Low level alerts notify users when to change the power module before the transmitter loses power. And the intrinsically safe design allows for the power module to be changed in the field, with keyed connections to ensure a fail-safe installation.
Proven Technology That is Easy-to-Use

 Easy to install, configure and commission

Training your staff on how to install and use new technology can be expensive and time consuming, not to mention that it’s just one more thing they need to remember. Emerson helps you keep it simple. With the Rosemount 708, you can leverage the knowledge and skills your staff already have. The transmitters have the same configuration and installation practices as wired HART, making additional training minimal. Power modules have a 10-year life and replacing them is a snap, thanks to their special design for error-proof installation

 Proven success in wireless field instrumentation

Selecting the right supplier of wireless field instrumentation is critical to the success of your steam trap monitoring implementation. In addition to evaluating features and functions, you want to be confident that the technology is going to install and work as promised. Choosing unproven technology could result in set-backs and even greater risks. Emerson's experience in wireless is unmatched in the industry, with over 5,100 operating networks globally and more than 450 million operating hours. From small start-up implementations to sites with thousands of devices, Emerson has helped customers in every industry succeed with wireless technology.

 Expert technical support

While our wireless architecture and applications are designed for ease of engineering, installation and use, we also offer a broad range of services to help you get up and running quickly – and make the most of wireless technology. With more than 4,100 trained wireless experts in all world areas, we will help ensure that your business needs are met through on-site emergency help, training, and factory support.

WirelessHART

Traditional wired technology can make process monitoring cost prohibitive, especially for measurement points that are in hard-to-reach or remote locations. The Rosemount 708 leverages the WirelessHART protocol, a cost-effective approach to wireless communication. An interoperable solution, WirelessHART enables you to make use of your existing HART devices, tools and knowledge, making it easy for your staff to implement. The self-organizing, self-healing network allows for simple and flexible implementations, so there’s no need for a site survey no matter how dense or obstructed the area may be.
