Laser pulse monitor

SpotLogger
The SpotLogger is a laser pulse monitoring system that uses a data acquisition board as a digital oscilloscope to monitor spot welding applications. It is very simple to use, you teach it what is a good weld and specify the tolerances.  Each spot weld has it’s own energy target and limits.  It sits behind your spot welding process, inspecting every pulse’s energy and signaling either a GOOD/BAD part, or aborting your process if your abort criteria has been met.  Digital outputs communicate with your PC, CNC or PLC controlling the process.

SpotLogger can act as both a controller and data-logger for documenting your spot welding process.

The system requires an analog output from your laser (or an optical measurement device) and a digital gate signal to synchronize the pulse. 

The SpotLogger software comes with an interface box and sells for $3000.00.

The data acquisition card is purchased separately from Keithley, model KPCI-3101 (current list price is $524.00).
