* The ECI 1118 also has a counterpart in the EBI 1135 model rotary encoder which retains the same slim design and high quality single-turn feedback while also offering the option for multi-turn capabilities via a battery-buffered revolution counter
. The revolution counter
can attain distinguishable revolutions up to 16 bits with an external battery connected.
Using a combined revolution counter
, and controller, the pump can be set to run for a predetermined number of revolutions.
Downie also explores the chemistry of solar cells and the fluid mechanics of a coffee-cup revolution counter
. Science teachers and inveterate tinkerers will find this book a joy.
Engineers attached a revolution counter
on the Humvee and a wheel counter on the fast-attack vehicle to calculate the vehicle's relative relationship to the target.
Based on American Gage Design standards introduced in 1945, dial indicator repeatability should be [+ or -] 0.2 of a graduation, accuracy should be within one graduation at any point in the measured range, and total spindle travel should be at least 2.5 turns of the dial, except special dials for monitoring variation from a high-noon zero position or single-revolution dials used to avoid measurement errors from misreading the smaller revolution counter
