Engineers often want to monitor a shaft’s rotational speed but get bogged down trying to get sensors, signal conditioners, cabling, and bulky housings to work together. To solve this dilemma, ...

Electro-Sensors, Inc. announces the ST420, a loop-powered, stainless steel analog shaft tachometer. The ST420 requires no user calibration, providing a dependable shaft speed monitoring solution right ...

If you’re into anything even vaguely mechanical on the broad hacking spectrum, you’ve come into contact with things that spin. Sometimes, it’s important to know precisely how fast they are spinning!

Tachometers directly report angular speed. Some are simple processors that merely digest output from an external sensor or encoder; others are integrated units that combine an encoder or sensor and a ...
