Infrared pyrometric system for temperature control with automatic adjustment of welding power

• Infrared pyrometer
• Electrical cabinet with user controls
• Industrial computer with close-loop control software
The pyrometer mounted perpendicularly to the pipe near the inductor zone, measures the temperature of the welding stripe on the pipe using an array of 14 sensors that sense a transversal temperature profile respect the pipe way. Two laser punters define exactly the width of the profile under measure. An air purge system for lens cleaning and an adjustable mounting fixture complete the mechanic support. The Industrial PC with a 12” touch screen runs software “Virtual Controller” developed by SITEL Control. In its multiple windows it is possible to monitor and check:
• The correct aiming of the pyrometer (it displays which of the 14 sensors is actually measuring the welding stripe).
• Working parameters configuration (It is possible to setup all values for power regulation and alarms).
• Pipe temperature (Instantaneous value of the welding stripe temperature).
• Working mode (if the pyrometer regulates automatically the welding temperature or not).
• Status of the preset alarms.
• Indication of welding power applied by the system referred to the one set manually with the potentiometer.
• Indication of the work program preselected.
• Indication of the file name used to acquire and store the temperature data.
• Graphic display in real time of temperature with indication of alarms thresholds.
The reordered data of temperature of the various production lots can be downloaded by an USB key or removable hard disk from the port on the control cabinet or directly by ethernet connection.
