Do you already have an old manual dyno you'd like to introduce to the 21st century?

The default setup is for a direct drive of the shaft the brake acts against. reach out before ordering to discuss other options. Many people will have some reduction ratio to minimize rotational speed at the brake, and \u003cspan\u003eaccommodations\u003c\/span\u003e for that can be made in software before shipping out to facilitate painless setup. It will work with various brake setups, disk, band, hydraulic loads, etc. \u003c\/p\u003e\n\u003cp\u003eThis package includes a 50 KG load cell, and the default is for testing up to 40 HP small engines. If you are uncertain if this will work for you, again, reach out and we can figure it out together. Any load cell range can be used, meaning the applications aren't limited to small engines. If you want some crazy load cell and wild graph number options, let me know, I can make that happen. \u003c\/p\u003e\n\u003cp\u003eThere is approximately 8 feet of cable on the load cell and 3 feet on the hall effect sensor allowing for varied component locating schemes. Common Delphi Weather Pack connectors for dependability and expandability. Extension cords could be easily made with commonly available parts. Let me know ahead of time if you think you may need one.\u003c\/p\u003e\n\u003cp\u003eThe M3 screws that come with the it are slightly long, allowing you to mount the screen on any flat surface between 1\/16\"-3\/16\" thick.\u003c\/p\u003e\n\u003cp\u003eLast but not least, there is always the open source nature of the product that allows you to expand the capabilities in ways limited only by your imagination.\u003c\/p\u003e\n\u003chr data-path-to-node=\"5\"\u003e\n\u003ch3\u003e\u003cbr\u003e\u003c\/h3\u003e\n\u003ch3\u003e💻 Interface and Testing Modes\u003c\/h3\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003cp data-path-to-node=\"11\"\u003eThe UI is intuitive and easy to navigate, designed for immediate and consistent results.\u003c\/p\u003e\n\u003cul data-path-to-node=\"12\"\u003e\n\u003cli\u003e\n\u003cp data-path-to-node=\"12,0,0\"\u003e\u003cb\u003e7\" 800x480 Capacitive Touchscreen:\u003c\/b\u003e The large high-res display makes interacting with the Pit Row Dyno a breeze.

This mode also allows you to spend some time with the machine and get a feel for how to use it. Repeatability really comes down to user error after a while; the more you use it, the more consistent your pulls will become and thereby the data you get from them.
