How to sanitarily measure vacuum in milk?

I would like to measure the vacuum inside of a tube which will contain air and milk. A vacuum pump attached to the tube will maintain a vacuum of around 15 inHg.

Are there inexpensive sensors I can use that will work in a milk environment and can be cleaned easily? I have never personally used an electronic pressure transducer and I worry that the milk will get into the inner workings of the transducer and either (a) ruin the transducer or (b) be inaccessible for easy cleaning.

I have found many inexpensive transducers on NXP.com, for example this one:

My concern with the sensors above is that the ported variants will be too difficult to clean and the non-ported variants look like they might have a small hole on the top of the sensor in which milk could get into (hard to tell from the line drawings if that is an open hole or a closed membrane).
