I have a 3bar moto map sensor, these things are TINY......for those of you who have them, where are you mounting them?

 

Go to radio shack or fry's and get a small project enclosure. Put it in there.

 

Hollow out a stock Map sensor housing like Madmax patented

 

Might try to do this if I can find the thread on it

I just went the 4 dollar radioshack project box route.

 

It's in my sig.

 

Pff no mounting required i just let it hand their

 

I'm pretty sure that the outside of the package needs to be exposed to atmospheric pressure to operate correctly. Could be wrong though. Wait, no, I'm right :



I *think* sealing that chamber could cause it to be inaccurate, but I'm probably just being paranoid.

Obviously it has a vacuum reference, but there could be offsets caused by pressures on the case. I know for a fact that if you say tighten the screws that hold them too much you will create wrong readings.

Just a thought before you bury one in epoxy or something.

I assume you guys are talking about the SMD type ones?

The motorola sensors are absolute...enclosing the case shouldnt pose a problem.

 

Fred, only gauge style sensors need P2 to be exposed to atmo. In the absolute pressure sensors, the P2 port is closed off and an almost complete vacuum is created behind the strain gauge sensor.
