The Micro ADM™ Sensor is a lightweight; compact, multi-sensor unit designed for monitoring and telemonitoring service purposes in a welding environment. The Micro ADM™ sensor is designed to provide the end user with a simple and cost effective, in-process weld monitoring system.

The Micro ADM™ Transducer includes an embedded micro-controller to provide the necessary data acquisition, signal processing and communications firmware to allow remote logging and testing of the following basic welding parameters: Arc Current, Arc Voltage, Wire Feed Speed and Shielding Gas Pressure.

This 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. 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. This cable also provides the Analog and TTL Signal Outputs to an external system data acquisition or PLC).

The Micro ADM™ provides total isolation of all sensors from the welding arc. Arc current is measured using a laser trimmed hall-effect transducer. Arc voltage sensor provides a 1 KV isolation using capacitive isolation technology.

The wire speed transducer is a precision optical encoder housed in a Delron body, for isolation and mechanical rigidity, with a heavy duty sealed bearing cartridge for increased durability. An integrated silicon differential pressure sensor provides torch shielding gas back-pressure measurements.

NetHub™ is an isolated RS-485 communications driver and power supply to connect up to six sensor units to the MODBUS™ RTU network.

A total of 247 sensors may be connected to the network using multiple NetHub™ units. Any Intelli-DART™, WireTrak™ or Micro ADM™ unit can be connected to the same NetHub™ unit.

The Intelli-DART™, WireTrak™ or Micro ADM™ units can be communicated with their appropriate software through the MODBUS™ RTU network.

The optional ArcTrak Plus™ program provides a GUI for the Micro ADM sensor using the ModBus RTU protocol. The Program allows the user to collect; graph and display weld data in a real time mode. The program provides a simple interface to configure the Micro ADM™ sensor parameter.

The sensor provides fault testing of the basic welding parameters (i.e. Volts, Amps, Wire Speed, Gas Pressure and Arc Time). It incorporates an advanced testing algorithm that provides three levels of fault testing. The sensor provides in-process parameter limit testing, Arc Density (AAD) for each weld in a Part and an ADD, Weld Count and Volume Applied test for each Part.

The sensor also features a Part Learn Mode that allows the sensor to establish statistical control limits based on actual production parts. The ArcTrak Plus™ program allows the user to upload run time weld data and stored SPC weld summary data. It also allows the user to graphically analyze the stored data and to view the internal sensor parameters and configure the basic sensor parameters.
