Iam looking for an off-the-shelf capacitive ring sensor, that I can use for gap/height control in my gas/plasma CNC machine.
The only site I found so far is : http://www.agelkom.com.tr/ in Turkey.
Are there any products available in US?
Looking for a economical solution.
Capacitive sensor torch height controls are primarily used for oxy-fuel cutting applications only, however if the majority of your cutting is on materials thinner than about 5mm, then you can use capacitive height control with plasma. With plasma, the capacitive sensor seems to get affected more by splatter, and most of the capacitive THC systems do not have the ability to control a separate pierce and cutting height. Hypertherm produces a capacitive sensor that could be used with plasma.. it is designed for industrial high production use, and is probably not the lowest cost solution, but would likely be the most reliable. Here is a link:
i also have some similar issues. I have 2 IHT's M4000 CAP, on which 2 oxyfuel torches are installed.
I am thinking to replace one Oxyfuel torch with Plasma system. I know what all things are required, buti dont want spend 7000Euros on IHT's M4000PCS. Can someone guide me if i can use THC with may be a bigger CAP ring.
