Description
Oxy-EVO Oxygen Analyzer
Precise purging is essential for controlling weld quality, particularly when welding high-alloy, corrosion-resistant materials. The Oxy-EVO oxygen analyzer can be connected to controllers for monitoring ID purge quality as part of the programmed weld schedule parameters. The entered oxygen value (in ppm) in the controller is arbitrary. If not otherwise imperatively prescribed, a value of < 30 ppm is generally sufficient at the beginning of the welding process. Welding will not commence until the measured value drops below the programmed threshold. The analyzer is calibrated to measure in the for welding relevant range below 30ppm up to +/- 2ppm precise.
The Oxy-EVO Oxygen Analyzer is equipped with a measuring cell made of zirconium oxide to help reduce the amount of required maintenance. The screen on the device is a 3.5″ touch panel with a simple navigation menu. Includes a color display for figures outside of the setpoint values.
This device includes both a digital and analog interface while also incorporating a Bluetooth transmitter to help the Oxy-EVO Oxygen Analyzer communicate with controllers and other PLC’s
Includes a USB interface to allow for the storing and retrieval of information form the device.
Equipped with user adjustable alarm limits and thresholds. In addition to the alarms there are also audible key tones to correspond with the actions made on the digital interface.
Oxy-EVO can be used for the following measurements:
• Oxygen content in inert gases (e.g. argon, helium, nitrogen)
• Oxygen content in forming gases (e.g. H2 2%, 5% & 10% in argon or N2)
• Oxygen content in special gases (e.g. argon-nitrogen-hydrogen gas mixtures)
• Differential pressure inside pipes (PPA extension, optional)
The analyzer is operated via a touch screen.
