Hey everyone I got a couple of old air pressure monitor pcbs, to salvage. I was wondering if anyone new what the blue device is. The only markings I can see are 001.

Seems to be the maker of your sensor, but I can not make out the part number on top, but maybe you can find it now.

Edit: sorry wrong part

Yeah I got the data sheet for the pressure sensor from allsensors it's the device beside it, it seems to be inline with the pressure sensor. The only markings visible is 001 on the top of it.

Do you know what the original use was?

I would guess a temperature sensor, often used with pressure sensors....

Looks like some sort of temp sensor, it was logging pressure temp and humidity, and I have the spec sheets for the pressure and humidiy. Now I just need to find what type of temp module this is.

I used to salvage all kinds of "stuff" & have the massive piles to prove it.  Since I forget what I have (some piles have been growing for 20 years), or can't find what I want (piles are here & there & even in forgotten places), nowadays I just order anything for $1 & get it with free shipping.  Of course I order spares & those go into the piles...

When in the dark remember-the future looks brighter than ever.   I look forward to being able to predict the future!

Well I only see two leads, (correct me if I'm wrong), so most likely a RTD.

See if you can ohm it out.

Provide further information?

 

  • Schematic of pneumatic connections (tubing) or a top view of the assembly.
  • Bottom view of the circuit board.

 

The blue device appears to have three tubing connections, a partly cylindrical body (for magnetic windings).

Could be a pneumatic SPDT reed valve for zeroing the other transducer.
