Signal Fire Wireless Telemetry has added the Sentinel-RTD as a new interface option to its Wireless Remote Sensing System to provide a direct connection to P100 2, 3, or 4-wire RTD sensors

The latest addition to Signal Fire’s Class I, Division 1 Sentinel node family, the Sentinel-RTD node operates in demanding outdoor industrial environments and offers a long life with an intrinsically safe battery pack.  Simple to install and maintain, the Sentinel-RTD offer a cost-effective option to wired solutions, costing less than 60 feet of installed conduit.

Utilizing long-range, mesh networking technology, the Signal Fire Remote Sensing System (SFRSS) contains “Sentinel” (and other types of) battery powered wireless nodes that interface with sensors.  The nodes extract data and then communicate that data to control devices via a Gateway.  The system has an open architecture that allows users to integrate many types of sensors, including RTDs, to monitor remote assets.  The SFRSS can be used to build a full wireless network using the best sensors for each sensing application point. 

For example, SignalFire’s wireless monitoring system can be used as a cost-effect way of monitoring and controlling assets well pads in upstream oil and gas facilities. Tubing and casing pressures as well as heater-treater temperatures, gas flare temperatures, tank levels, flows, well shut-in, RTUs and other oilfield measurements and controls can be seamlessly integrated into a single system using the SignalFire Telemetry system.
