轉速計，又名轉速表、轉速儀，是機械行業的儀器之一，用來測定電機的轉速、線速度或頻率。常用于電機、電扇、造紙、塑料、化纖、紡織、汽車、飛機、輪船等制造業。大多常用的為手持離心式轉速計。

轉速計，又名轉速表、轉速儀，是機械行業的儀器之一，用來測定電機的轉速、線速度或頻率。常用于電機、電扇、造紙、塑料、化纖、紡織、汽車、飛機、輪船等制造業。大多常用的為手持離心式轉速計。美國Checkline旗下的轉速計一般為數字式，有接觸式和非接觸式兩種測量。非接觸式采用光電器件測量，無連接軸，對被測件無任何影響，提高測量精度。

例如Checkline YSL-2000HD型是一款接觸式&非接觸式轉速計，精準測量轉速，速度，表面速度和長度。適用于紗線，細絲，軸，電機，輪滑，傳送帶，造紙網和織物網。

The CHECK-LINE YSL-2000HD combines the functions of three separate instruments in one, easy-to-use device.

It accurately measures the speed and length of yarns, and other filaments using a unique "wrapper" roller. This precision roller directs the filament onto the low-inertia, U-grooved measuring wheel to maximize contact and eliminate filament slip and breakage.

The Check-line YSL-2000HD can also be used as either a contact or non-contact tachometer to measure rotational speeds of shafts, motors, pulleys, etc. or linear speeds of moving surfaces such as conveyor belts, webs of paper or fabric, etc.

Slide-on measuring heads make it simple to rapidly convert from one function to another
