Wireless remote sensing system supports 2, 3, or 4-wire RTD sensors

04 November 2015

Signal Fire Wireless Telemetry has added a new interface option to its Wireless Remote Sensing System. 

The latest addition to Signal Fire’s Class I, Division 1 Sentinel node family, the Sentinel-RTD provides a direct connection to P100 2, 3, or 4-wire RTD sensors. 

Designed to operate in demanding outdoor industrial environments, such as often found in the oil and gas industry, the Sentinel-RTD is said to offer a long life with an intrinsically safe battery pack. An optional Class 1, Division 1 solar system is available for installations where it is not practical to utilize batteries. Simple to install and maintain, the Sentinel-RTD offer a cost effective option to wired solutions; costing less than 60 feet of installed conduit. 

Utilising 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 featurs an open architecture which allows users to integrate a variety of sensor types, 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, says the company.  

The wireless monitoring system could be used as a cost-effective way of monitoring and controlling assets in upstream oil and gas facilities. It allows 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.
