1.0 SYSTEM OVERVIEW  

1.1 General 

Overview 

The Micro ADM™ Sensor (A3A0226) is a lightweight; compact, multi-sensor unit 
designed for monitoring, Parameter Testing and telemonitoring service purposes 
in a welding environment.  The Micro ADM™ Transducer includes an embedded 
micro-controller to provide the necessary data acquisition, signal processing and 
communications firmware to allow remote logging/testing of the following basic 
welding parameters. 

 Arc 

Current 

 Arc 

Voltage 

  Wire Feed Speed 

  Shielding Gas Pressure 

The light weight, easy to install design allows the user to install the Micro ADM™ 
at the wire drive motor inlet using industry standard quick disconnect conduit 
fittings or to a fixed surface with the optional mounting brackets (A2A0025). The 
LED indicators provide the operator or maintenance personnel with a quick visual 
indication of sensor activity.  

The unit is powered by a user supplied external 24 VDC power source via the 
sensor interface cable (A3W0327). This cable also provides an RS-485 Full-
Duplex serial communications port to an external system (data acquisition or 
PLC).   A second Remote I/O cable (X3W5102) is provided to allow an external 
PLC/Robotic controller to control and monitor the sensors’ embedded fault 
testing routines.
