The difference between transducer tip and measuring tip
The transducer has 2 ends.
Transducer tip is mounted to the one of the ends
The transducer tip is mounted via spring so it can be pushed/pressed in up to +/-2.048 mm, while the measuring tip is connected as a screw to the transducer directly or through extension bars as it has a thread.
The measuring tip is connected to the other end directly or through the extension bars.
