im from peru...thanks...I am a student and an oscilloscope like picoscope is unattainable for me, with inflation in my country everything has become expensive.... I am going to do my best to make myself a pressure transducer with honeywell.... greetings and successes teacher..............saludos desde peru

Great video !! Thanks for sharing mate!

Great video and comparison, Sean! I thank you for introducing me to this platform.

Love comparison videos.

Excellent. Keep it up.

Pretty power box!! No hot glue 🙂. RE: I just watched your $20 vibration analyzer it was fantastic too.

Thanks again for the break down. There is a Chinese version that works really well also. Similar to the WPS for about 300 bucks

Hi, That was an interesting video in which different sensors and scopes are featured. However, I was wondering if you get hold of a sensor from ATS - Bernie Thompson- and compare its response and vertical resolution with Pico's WPS500.

Thank you very much for this informative demonstration. I have some of these sensors and they are all 1/8'' NPT but in the market, I can't find any of the adaptors that you use in this demonstration. Can you please help me with this?

The higher compression pressure during snap throttle is from the ingestion of more air to the cylinder,it is not back pressure. With modern cylinder heads and intake manifolds flowing more air this is the result, more power.

Hi Why is the waveform different in the initial test before starting. Like the valves are not opening?

Can you please compare the wps to rotkee p16?

Ivan, at "Pine Hollow Auto Diagnostics" --- sells his own little kit. I forget what sensors he uses.

I am just wondering if you use the same Pico sofrware for the 12 byte and 8 byte scopes. Great video. I have just purchased a cheap Rotkee sensor and look forward to seeing its performance

For the 8-bit scopes, you’ll need the non-automotive version of Pico. You can get it at picotech.com.

BENXU-TECH make good sensors. Less stair stepping than my honeywell px3. $20 but there not absolute.

I want to get into in cylinder testing which one would you recommend?😊

Exelente aula poderia falar. Pouco devagar difícil acompanhar a tradução! Por favor

Back when the vantage scope came out I bought all the pressure transducers and cables. Haven't used them in years since the Vantage died. not sure how to wire it. Do you have description of pin out for the connector

I’m not sure the pin out. I’m pretty sure those snapon sensors alter amperage, not voltage. They likely switch between 5-20mA, which is a common range. With the pico, you can still use that setup, but you have to feed it 5v through 250 ohms. Then you can measure the voltage drop across the resistor and make either a math channel or create a “custom probe”. That sounds like a good project for another video!

@@siuautomotive That does sound like a great subject for another video. The SSI transducers you are using look identical to the ones I have, round three pin connector, shape of the body, everything. Do the SnapOn transducers you're talking about meet that same description? I've got a range of transducers that go from reading vacuum and low pressure on up to 5000 lbs. It'd be nice to make use of them.

Hi my scope doesn't support rollers for in cylinder pressure, engine rotation. Is there any software that allow to overlay that pattern to my measurements?

Muy buen video pero yo fabriqué uno y no logré q funcionara ni diera lectura

Vtc Cam advance increase compression.

Veo q tú lo fabricaste sería x el sensor de precion

Bom dia. Onde compro o sensor SSI P51-500-S-G-P

For those who read my reply about Rotkee transducers: they are bad, they brake after 10 uses: the black "ground" wire burns and melts. I checked the resistance of wires, check connections, checked clamps for power supply, etc, and established that transducer itself creates super-high current when pressure is 50 psi. As soon as pressure drops to zero, the burning stops. I posted reviews on Google sites about it.

Any chance of a comparison of the JH APT 100 clone of the WPS 500 tranducer? It comes with the adapters, and case. I have one, but haven't used it yet. Seems reasonably well built. kzread.info/dash/bejne/dJaeo62ldtGqctI.html

Hmmm, I’ll have to look into that. It really looks like a clone of the wps. For less than $300, it looks like a great deal. I do hate the fact that those China companies are cloning other companies great products though
