The SignalFire Sentinel wireless node connects to sensors and creates a wireless link between the sensor and a Gateway. This wireless node is intrinsically safe (Class 1, Division 1) and can interface to sensors via a variety of interfaces – Analog (4-20mA/1-5V), Modbus, HART, and Digital Input. The Sentinel has a range of 1/2 mile and is part of the SignalFire mesh network bring wireless connectivity to the oil field. The Sentinel wireless node will power the sensor, take the data, and send the data (via the SignalFire wireless mesh network) to the Gateway where the data is available via a Modbus RTU or TCP interface. This product line is powered by internal lithium batteries. C1D1 solar power option is available for sensors requiring long warm-up times or if an always-on sensor is desired. Sensor data along with diagnostic information is available at the Gateway. Learn more about process automation products available from BBP.
