SignalFire Introduces Remote Sensing System
The SignalFire Remote Sensing System (SFRSS) integrates an open architecture mesh network that allows users to choose the preferred sensor type for an application and mix sensor types in the same network. The SFRSS communicates and powers virtually any sensor with 4-20 mA, 1-5V, Modbus, Hart, digital IO and other analog and digital interfaces.
In a typical tank level monitoring application, SignalFire wireless “nodes” interface with a standard sensor, providing power for the sensor and connectivity to a “gateway” located at a central location where data is concentrated. The SFRSS transports the data to the gateway via its wireless mesh system.
Because the SFRSS mesh network operates at lower frequencies, it can communicate at ranges of up to three miles between nodes and is significantly less sensitive to foliage, obstructions and moisture, according to the company. The SFRSS can power both sensors and the radio system from either internal batteries or a specially designed solar system to remain truly wireless. While battery life depends heavily on the sensor, it can last from one to 10 years.
SignalFire offers its Remote Sensing System (including a solar power option) with Class 1 Division 1 certification for intrinsically safe operation as many tank level applications require products to be certified for hazardous use.
