Barometer placement inside a nema4 enclosure

(1/2) > >>

sho23:
Is the placement inside of a (fairly) waterproof box hampers the sensor reading? Should I be running an air hose to the outside somewhere?

We've installed a few out there, and they do react, but perhaps that's simply because some of our penetration into said enclosure isn't perfect.

   It needs to breath to properly work, your enclosure creates a smoothing effect and a delay depending on how fast the air can leak in or out. If your sensor  has a port on it for a hose the proper thing to do would be to put tubing on it  going outside and then attached to a gill plate. You could just stick the hose out but if the wind is blowing the hose can act as a venturi and cause bad readings.

Excellent point as it would create a probable vacuum at times, at least enough to yo-yo the data.

If we need to put a pressure sensor inside of an enclosure, we toss at least two of these on the enclosure:

Drill a 1/16th hole in the bottom of the enclosure:
