激光轉(zhuǎn)速探頭簡(jiǎn)化了轉(zhuǎn)速測(cè)量

LUYOR推出ROLS-5PW型激光轉(zhuǎn)速測(cè)量探頭，該激光轉(zhuǎn)速測(cè)量探頭可以使高速旋轉(zhuǎn)機(jī)械的測(cè)試更安全、更簡(jiǎn)單方便。激光轉(zhuǎn)速傳感器ROLS-5PW用于旋轉(zhuǎn)機(jī)械非接觸式轉(zhuǎn)速測(cè)量，測(cè)量范圍為0RPM至300,000 RPM。激光轉(zhuǎn)速監(jiān)測(cè)傳感器適用于風(fēng)力發(fā)電機(jī)或船舶推進(jìn)器之類的極低轉(zhuǎn)速測(cè)量，以及增壓器之類的ji高轉(zhuǎn)速測(cè)量。工作距離為可達(dá)7米。

ROLS-5PW激光轉(zhuǎn)速探頭是一款小巧堅(jiān)固的IP60級(jí)激光轉(zhuǎn)速測(cè)量傳感器，用于對(duì)旋轉(zhuǎn)或往復(fù)式機(jī)器部件進(jìn)行非接觸式速度測(cè)量，通過(guò)機(jī)器元件反射的激光的傳感器每次旋轉(zhuǎn)產(chǎn)生電壓脈沖來(lái)工作。激光轉(zhuǎn)速探頭的位置使其可見(jiàn)激光束面向測(cè)試對(duì)象，測(cè)試對(duì)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(wú)抖動(dòng)信號(hào)，可以輸入到測(cè)量?jī)x表或存儲(chǔ)記錄儀。

使用反射膠帶意味著激光轉(zhuǎn)速傳感器ROLS-5PW可以放置在距離測(cè)試對(duì)象7米的地方，因此工程師在測(cè)試許多不同類型的高速機(jī)械時(shí)可以保持安全距離，包括從飛機(jī)渦輪機(jī)到工程機(jī)械等各種測(cè)試對(duì)象。該裝置的緊湊尺寸也使其適用于訪問(wèn)包含在受限區(qū)域內(nèi)的機(jī)器部件。

LUYOR 公司的ROLS-5PW可以在高達(dá)300000rpm的轉(zhuǎn)速下運(yùn)行，這對(duì)于增壓器測(cè)量以及低速測(cè)量（取決于數(shù)據(jù)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.
