In this video I use my home made low-pressure transducer along with the PicoScope featuring custom scales. Looking at your backpressure from the driver's seat sure beats looking at a mechanical gauge hanging under the truck! Enjoy! Ivan P.S. Let me know in the comments if there is any interest in a custom-tailored pressure transducer kit, and if you want to see a video describing the custom kit and its capabilities 😃 Wed, 13 May 2026 15:50:41 GMT https://validator.w3.org/feed/docs/rss2.html PeerTube - https://stream.echo6.co https://stream.echo6.co/client/assets/images/icons/icon-512x512.png https://stream.echo6.co/videos/watch/90098d7d-151f-45fa-bf20-0b27c058bfc5 All rights reserved, unless otherwise specified in the terms specified at https://stream.echo6.co/about and potential licenses granted by each content's rightholder.
