B737 cabin pressure sensor

[turboP]

Guys,

Tried to find out in all books I have, but no result. Does anybody know where the Cabin pressure sensors/ports (737) are exactly located? (there should be 2 AFAIK). thanks for replies.

On the CPC....If I remember well.A port to the Pack valve from the Aft wall of the FWD Cargo compt had a line each to each Packvalve.

737 classic or Ng? Control or warnings/ mask drop?

Classic or NG?
Do you mean cabin pressure sampling for control or cabin pressure warning and rubber jungle?

I was thinking ceiling of fwd e&e (like the NG) for alt warning.
Certain for NG, not certain for 737-3/400.
rubber jungle drop in j23 main e&e on NG if i remember correctly.
