Southern Technologies

Sentry 2058
Introduced in 1986 as the company's first detector offering. While most units came equipped with bearing scanners, Southern Railway/Norfolk Southern instead opted to use detectors that scanned the end of the axles at a lower temperature threshold. Common users include Conrail, Norfolk Southern, & Southern Pacific.

Sentry 2100
The Sentry 2100 was a transition model primarily employed by BN & BNSF. Their radio transmissions sound identical to a SmartScan NG, but predate them by approximately a decade.

SmartScan NG
Built upon the proven success of the Sentry System, the SmartScan Next Generation (NG) started production in 2004. Featuring dual processors and networking capabilities to back office systems, as well as the ability to integrate with an AEI reader, it is a substantial upgrade over its predecessor.

SmartScan NG²
Introduced in 2017, the latest generation of hot bearing detector includes significantly upgraded processors and a computer synthesized voice. Its improved processing capabilities allow for trains of over 4,000 axles to be scanned, and its modular structure makes for a very simple upgrade of an existing SmartScan NG site.

Small Talk
A very basic talker unit designed to allow easy & economical replacement of older non-hot bearing capable models. Not nearly as feature-rich as the iCUBE that succeeded it, although it did support transducers for axle counting.

iCUBE
A non-hot bearing-capable unit that can be utilized for dragging equipment, high & wide loads, high water detection, wind speed, ambient temperature, and much more. It can also be used as a DTMF switch or grade crossing controller, switch position monitor, or an annunciator for a WILD detector. It also features the same advanced networking capabilities to back office systems as its SmartScan brothers. The iCUBE was introduced in 2014.
