C# How do I get CPU load from application PID

Greetings :)
I have an application named Test.exe. Inside this application I can immediately get its own name and process ID like this:

string processName = Process.GetCurrentProcess().ProcessName;

int processID = Process.GetCurrentProcess().Id;

Using performance counters, inside Test.exe, I can get the CPU load of itself using the application name.

Now for the point. I run 10 instances of Test.exe. Each one has its own separate PID or process Identification Number assigned to it by the OS. I need to let each application of Test.exe sample it's own CPU load. Therefore I have to detect CPU load via the PID since there are 10 instances of the same application running.

Any pointers or samples much appreciated. :)
