Vibrating Reed Tachometers. Simply held against motor, turbine, pump, compressor, or other rotating equipment and the speed is shown by the vibration of a steel reed which is tuned to a certain standard speed.

A reed tachometer doesn't look like a normal speed measuring tachometer it's different.

It's purpose itself is to measure vibrations in the transverse direction.

But we keep the tachometer along the axis of rotation @Sohel.

Sohel said:   9 years ago
Transverse vibration occurs perpendicular to the axis and since we measure the speed with tachometer keeping it at right angle to the actual axis, thus the answer is C.

A tachometer is an instrument measuring the rotation speed of a shaft or disk.

Please explain it clearly.
