The SpeedTalker DN (UI) DeviceNet shaft-speed tachometer converts pulse-train frequencies from a wide range of single-ended or differential, single-channel, or quadrature sensors into rpm units.

Every Hot Rod should have a tachometer, and if yours didn't come with one you've got a ton of options. With a Benjamin as the budget, we decided to test seven models from Summit Racing to see how ...

The 2022 Nissan Frontier was unveiled last week and on first impressions, it appears to be far superior to the outgoing model. However, there is one oddity that has caught the attention of some social ...

The circuit shown in the figure below will have a display reading of “1999” for an input frequency of 33.33Hz (equivalent to 1999 rpm). The 0.0477µF capacitor (C1) should have a ...

The average modern car has a bewildering list of acronyms, and it starts from the moment you sit in the driver's seat. Upon turning the ignition or pushing the start button, a cacophony of dashboard ...

Ever since the first race cars were built, it's been helpful for drivers to know their engine speed. It may sound obvious, but engine power is always a function of engine speed, so accurately knowing ...

RPM stands for revolutions per minute, and in cars, it measures how many times the engine’s crankshaft makes one full rotation every minute and how many times each piston goes up and down in its ...

It’s the latest in instrumentation for the well-appointed shop — an acoustically coupled fast Fourier transform tachometer. Sounds expensive, but it’s really just using a smartphone spectrum analyzer ...

The circuit shown in the figure is a three-digit tachometer that lets you measure low-frequency events recurring at intervals of 0.235 to 15 seconds--that is, from 4 to 255 rpm. Thus, it's suitable ...
