例如Checkline CDT-2000HD型轉(zhuǎn)速計(jì)，兼有接觸式與非接觸式兩種測(cè)量方式，精準(zhǔn)測(cè)量轉(zhuǎn)速，表速和長(zhǎng)度?？蛇x用Checkline CDT-1000HD型。
CDT-2000HD運(yùn)用：
The CHECK?LINE® CDT-2000HD Combination Hand-Held Digital Tachometer combines the best features of both contact and noncontact models to accurately measure RPM, surface speed and length. When using the non-contact mode, rotational speed (RPM) is measured using a visible beam of light. The CDT-2000HD can be up to 24 inches away from the small piece of reflective tape that is affixed to the rotating element. In the contact operating mode, the speed is sensed by directly contacting the rotating device using the cone tip or surface speed wheel supplied with the instrument. The CDT-2000HD's rugged construction, portability and outstanding features make it an ideal choice for maintenance personnel, machine operators or others in a wide variety of machinery and material handling applications.
CHECK-LINE便攜式手持?jǐn)?shù)字轉(zhuǎn)速表CDT-2000HD，廣泛運(yùn)用于不同機(jī)械和材料處理應(yīng)用程序。集成接觸式和非接觸式兩種模式，測(cè)量更加精準(zhǔn)，可測(cè)轉(zhuǎn)速，線(xiàn)速度和長(zhǎng)度。在非接觸模式下，通過(guò)可見(jiàn)光束測(cè)轉(zhuǎn)速?？梢栽诰嚯x測(cè)量件小片放光帶24英寸的情況下測(cè)量。在接觸式模式下，運(yùn)用自帶配件錐頭和表速輪接觸旋轉(zhuǎn)裝置來(lái)感應(yīng)速度。CDT-2000HD機(jī)身結(jié)實(shí)、使用便攜和，是維修人員，機(jī)械操作員和用戶(hù)的理想之選。
