    I used a 1" PVC quick disconnect and two plugs with a 35mm sensor. Works perfect.

    • @forkliftgeek10
      @forkliftgeek10  3 роки тому

      I don't think there would be a difference since the voltage produced would be AC.

    • @forkliftgeek10
      @forkliftgeek10  3 роки тому +1

      During testing though, you apply positive pressure and make sure the voltage goes up and with negative pressure the voltage goes below zero. If it was the other way you reverse the connection.

    Hi, I have been looking for a BNC connector like the one you used on this video.I ordered some on AMAZON but they are too small.
    I looked for the number on the package you have 21-37-1 but could not find it.

    Great video. You can buy these piezo sensors with an aluminium cover would they work just as well or would it affect the sensitivity?

  • @stanleynelson5102

    Hello, Your piezo sensor looks to be about 45mm diameter. Do you think we could get by with a 35mm diameter sensor. That size is readily available but larger sensors are not. Naturally the PVC fittings would have to be smaller as well.

    • @forkliftgeek10
      @forkliftgeek10  6 років тому

      +Bill Nelson i dont think there would be a problem with that. Although I've never tried it with a smaller piezo before. But the reaction of the sensor should be same.

    hello , do you think that can be use as a vacuum transducer? you know to check negative intake pressure

    • @forkliftgeek10
      @forkliftgeek10  8 років тому

      +david cisneros if you want to get the vacuum reading of each cylinder then the answer is no. This tool is used to see if the cylinders are drawing vacuum equally. If you want to be able to get the vacuum reading of each cylinder then a MAP sensor would be more appropriate. But you need an oscilloscope that can give great detail.

    • @david619dc
      @david619dc 8 років тому

      +ForkliftGeek that's what I thought , Ok so MAP or FTP would do huh.

    • @forkliftgeek10
      @forkliftgeek10  8 років тому

      +david cisneros yes a MAP sensor would give you a voltage reading corresponding to manifold pressure. But the reading is the average of all cylinders, to see each cylinder pull you have to zoom in quite a lot. That's why I said you need a scope that give great detail even when zoomed in. Fuel tank sensor is good for exhaust.

    I noticed piezo sensor had 3 wires then u must have removed the red one,my piezo has 3 spring loaded leads instead of hardwired ones like yours.question should I look for another smoke alarm or should I be OK soldering wires to piezo,my concern was solder heat,come to think about I might just use conductive adhesive Give me your opinion.this weekend I'm building one like yours and one with a fps and a few high psi transducers

    • @forkliftgeek10
      @forkliftgeek10  8 років тому

      +harvey jackass I've had to solder wires directly unto the piezo before and was ok so I don't see any problem with that. Fps works fine with exhaust pulses but u have to use a map sensor if you want to see intake vacuum pulses.

    • @alanw5879
      @alanw5879 4 роки тому

      If you use a map sensor, does it need a 5 volt reference to read correctly, or is it just the bending of a board or something in a map that changes resistance?

    • @forkliftgeek10
      @forkliftgeek10  4 роки тому

      The MAP sensor needs a 5v supply and a negative to work.

    Bro, your rubber hose is way too long, look at older engines with MAP sensors, they started out with longer vacuum hoses, then the sensors were moved closer to the manifold then the MAP was mounted on the manifold. The pressure pulses in longer hoses are baffled or softened and don't give a very accurate waveform. This post is for future readers of your nice video, thanks.
