Devtronics has the distinction for holding the patent for the world's first micro computerized talking hotbox detector.

In 1997, Harmon Industries purchased Devtronics.

Defect Detectors (Heat Sensing)

68178

Early model utilizing a Servo tube front-end (such as the 7621 or 7707)

CMA02

Another early model, this one using a Servo solid state front-end (such as the 8808 or 8909).

TSA3000

More information is needed about this particular model.

Defect Detectors (Non-Heat Sensing)

UT-1

An earlier model used to detect high/wide loads and dragging equipment.

Supervisory Control Alarm Telemetry (S.C.A.T.)

Introduced after the UT-1, the S.C.A.T. was designed to detect high/wide loads and dragging equipment.

Overlay Systems

MA1B (Mini-Analyzer)

The MA1B was an interface used with older, non-talking hot bearing detectors to allow them to analyze & transmit the results via radio. The Mini-Analyzer was for detectors that did not have a built-in alarm capability, meaning the Mini-Analyzer would analyze the scanner inputs itself and provide alarm functionality.

MT2A (Mini-Talker)

Like the MA1B, the MT2A was utilized with non-talking hot bearing detectors to allow them to transmit the results via radio. The Mini-Talker was used with detectors that already had alarm functionality, and thus simply allowed them to transmit the results via radio.
