ADM™ Micro Arc Data Monitor |
- 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™ 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.
|
|
- 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.
- 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).
- NetHub™
is an isolated RS-485 communications driver and power supply to connect up to six Micro ADM™ Sensors to the MODBUS™ RTU network. A total of 247 sensors may be connected to the network using multiple NetHub™ units.
- 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 Micro ADM™ sensor is designed to provide
the end user with a simple and cost effective, in-process
weld monitoring system.
