That design is perfect… as long as you can maintain the seal around the wires… because now the electronic device out of the main air stream.? Now the connection to the air stream can be to a simple plastic barb (cut off so that it doesn’t protrude into the airstream pipe.? Just cut flush with the inside wall).? That is absolutely ideal.

Hi K9HZ,

How about this mod.? I placed the BMP180/280 in 3D printed carrier and placed that sub-assembly in a separate section of PVC.? The connector to the BMP module exit one side.? The hose barb at the end lets this module be replaced, if needed, while still being able to get accurate pressure readings.?

And we can put this module in the controller. It's similar to Gordon's with the addition of a part to hold the BMP in place.? I think we need to keep it in place as the pressure changes could bang it around and break wires or etc.

Virus-free.
