Wherever there is a risk of combustible or toxic gas leaks accurate air monitoring is essential. Storage tank entry and exit points, joints subject to thermal expansion and contraction or heavy vibration are all prone to leaks.
In the past, operators had to either patrol their installations with hand-held gas sniffers or install hard-wired systems to sample the air at regular intervals. But each of these approaches has its drawbacks. Foot patrols are labor-intensive and less than reliable. Hard-wired detection systems are expensive to install, involving tremendous amounts of planning, design, engineering, materials, and labor.
Now, there’s a better way. The Vanguard WirelessHART® Toxic and Combustible Gas Detector is the first truly wireless device to report hazardous gas levels through a self-configuring WirelessHART network. It’s tough, reliable, and easy to install.
Once you’ve set up a Wireless HART® network gateway at the site, any number of Vanguards can be installed quickly and easily to create or supplement an existing gas-detection system. The Vanguard comes with its own sensor, a five-year battery, instrument display, and antenna for network communication to a SCADA, DCS, or Remote Terminal Unit.
Each Vanguard is easily installed and functions as a node on the network being both a client and a repeater, to extend the network further with each jump. Connecting the sensors through an existing wiHART® mesh takes only a few minutes.
Each Vanguard has its own display, allowing for quick, one-button field calibration. While the upfront hardware cost for each wireless unit is greater than that of conventional hard-wired gas-detectors, the real savings are realized in the ease of installation. And the solution can be deployed in a matter of days, not months.
Wherever fast installation and reliable monitoring are needed, the Vanguard WirelessHART® Toxic and Combustible Gas Detector can save time and money, while protecting valuable lives and assets.
