Device supports wireless monitoring of field assets
Signal Fire Wireless Telemetry
The Sentinal-RTD (photo) is the latest interface option that can be added to this company’s Wireless Remote Sensing System, to support two-, three- or four-wire RTD sensors. As part of the company’s Class 1, Division 1 Sentinel node family, the Sentinel-RTD provides a direct connection to P100 2-, 3- or 4-wire RTD sensors (and other types are available upon request). The device has a long life with an intrinsically safe battery pack, making it especially well-suited to function reliably in demanding outdoor industrial environments (such as oil-and-gas operations). The Signal Fire Remote Sensing System (SFRSS) uses long-range, mesh-networking technology, and uses Sentinal (and other types of) battery-powered wireless notes to interface with the sensors. The nodes extract and then communicate data to control devices via a gateway. The system has an open architecture, which allows users to integrate many types of sensors, including RTDs, to monitor remote assets. In this way, the SFRSS can be used to build a full wireless network using the best sensors for each sensing application point. — Signal Fire Wireless Telemetry, Hudson, Mass.
