What is a "phase angle" in a mechanical drawing?
What is a "phase angle" in a mechanical drawing?
(OP)
Hi all,
The following mechanical drawing is for a pressure sensor and recommends a 19mm hole with a 20 degree phase for mounting. What does a 20 degree phase mean?

Thanks,
Amr

Phase auf Deutsch = phase

Doug, I think it's fase.
Thanks Mikey - phase it is.

Ask for a drawing of the thing you must mount there.

@Jboggs: Because interestingly enough, I get quicker responses on the forum!

This thing looks like some sort of push fit?
The plug at the base is only 3mm deep with an OD of 18.4mm
does the phase refer to the final taper angle to stop this thing going all the way through the hole?
I think it's difficult because we only have one little bit of the drawing.
Remember - More details = better answers
Also: If you get a response it's polite to respond to it.

This is a very exact hole, 19mm + 0.033mm, - 0mm (H8)
Or in the attached do you think it is the angle marked 15 to 30o on the top left?

Using the word "Phase" instead of "Fase" is a translating error. The word "Phase" can have many different meanings in German. Anywhere from a period of time to electricity. That is why one should be very careful when using computer translations for technical terminology. The will kill you. In this case the correct word "Fase" -chamfer or bevel is pretty obvious.

I think it's pretty clear.
