激光轉速探頭簡化了轉速測量
LUYOR正在推出ROLS-5PW型激光測速探頭,該激光轉速探頭可以使高速旋轉機械的測試更安全、更簡單。
ROLS-5PW激光轉速探頭是一款小巧堅固的IP60級激光轉速傳感器,用于對旋轉或往復式機器部件進行非接觸式速度測量,通過機器元件的每次旋轉產(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械時可以保持安全距離,包括從飛機渦輪機到洗衣機等各種測試對象。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)的機器部件。
LUYOR表示,ROLS-5PW可以在高達300000rpm的轉速下運行,這對于增壓器測量以及低速測量(取決于分析系統(tǒng))也足夠用于風力渦輪機和船舶推進系統(tǒng)等應用。
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.
