激光轉(zhuǎn)速探頭簡化了轉(zhuǎn)速測量

LUYOR正在推出ROLS-5PW型激光測速探頭，該激光轉(zhuǎn)速探頭可以使高速旋轉(zhuǎn)機(jī)械的測試更安全、更簡單。

ROLS-5PW激光轉(zhuǎn)速探頭是一款小巧堅固的IP60級激光轉(zhuǎn)速傳感器，用于對旋轉(zhuǎn)或往復(fù)式機(jī)器部件進(jìn)行非接觸式速度測量，通過機(jī)器元件的每次旋轉(zhuǎn)產(chǎn)生電壓脈沖來工作。探頭的位置使其可見激光束面向測試對象，測試對象上貼有一小條自粘鏡反射膠帶。然后，該反光貼紙將激光能量反向散射到接收器，接收器將其轉(zhuǎn)換為無抖動信號，可以輸入到測量或存儲記錄儀。

使用反射膠帶意味著探頭可以放置在距離測試對象7米的地方，因此工程師在測試許多不同類型的高速機(jī)械時可以保持安全距離，包括從飛機(jī)渦輪機(jī)到洗衣機(jī)等各種測試對象。該裝置的緊湊尺寸也使其適用于訪問包含在受限區(qū)域內(nèi)的機(jī)器部件。

LUYOR表示，ROLS-5PW可以在高達(dá)300000rpm的轉(zhuǎn)速下運(yùn)行，這對于增壓器測量以及低速測量（取決于分析系統(tǒng)）也足夠用于風(fēng)力渦輪機(jī)和船舶推進(jìn)系統(tǒng)等應(yīng)用。

Laser Tacho Probe simplifies rotational speed measurement

LUYOR is launching the Laser Tacho Probe Type ROLS-5PW, which is said to make testing high-speed, rotational machinery safer and simpler.

A small, robust IP60-rated probe for contact-free speed measurement on rotating or reciprocating machine parts, the ROLS-5PW works by producing a voltage pulse from each rotation of a machine element. The probe is positioned so that its visible laser beam faces the test object, to which is attached a small strip of self-adhesive retro-reflective tape. This tape then backscatters the laser energy to a receiver that converts it to a jitter-free signal that can be input to a measurement or recording system.

The use of reflective tape means the probe can be positioned up to 70cm from test objects, so engineers can maintain a safe distance when testing many different types of high-speed machinery, encompassing everything from aircraft turbines to washing machines. The unit's compact size also makes it suitable for accessing machine parts contained within restricted areas.

LUYOR says the ROLS-5PW can operate at rotational speeds of up to 300,000rpm, which is sufficient even for supercharger measurements, as well as low-speed measurements down to standstill (dependent on the analysis system) for applications such as wind turbines and ship propulsion systems.
