Installation
Sensor Mounting
The sensor connection is thru the coax cable to the sensor mounting isolator. It is the
responsibility of the installer to provide a mounting clamp that will correctly position the sensor
ring with respect to the torch tip. The mounting clamp should be designed for a center of torch to
center of isolator distance of 2 inches or 50mm so that that the sensor ring will be properly
centered and positioned around the torch tip. Additionally, the mounting clamp should provide a
good ground electrical connection between the sensor mounting isolator and the machine frame.
