Pressure monitoring in station

Authorities were quick to say that the latest "crunch sound" didn't result in
any pressure change in the station.

How do pressure monitors deal with temperature variations ? If they are so
precise that they can monitor the slightest pressure change, wouldn't they be
affected by an increase or decrease in temperature somewhere on the station ?

I imagine they are sensetive to "sudden" changes and trip on violation of
"expected limits"

I'm not sure what the ISS instrumentation sensitivity levels are.
Ground specs. are typically +/-0.1% full range for pressure and +/- 3
deg F for temp. Temp. changes resulting from small pressure changes are
in the noise.
