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yong於yu對dui旋xuan轉zhuan或huo往wang複fu式shi機ji器qi部bu件jian進jin行xing非fei接jie觸chu式shi速su度du測ce量liang，通tong過guo機ji器qi元yuan件jian的de每mei次ci旋xuan轉zhuan產chan生sheng電dian壓ya脈mai衝chong來lai工gong作zuo。探tan頭tou的de位wei置zhi使shi其qi可ke見jian激ji光guang束shu麵mian向xiang測ce試shi對dui象xiang，測ce試shi對dui象xiang上shang貼tie有you一yi小xiao條tiao自zi粘zhan鏡jing反fan射she膠jiao帶dai。然ran後hou，該gai反fan光guang貼tie紙zhi將jiang激ji光guang能neng量liang反fan向xiang散san射she到dao接jie收shou器qi，接jie收shou器qi將jiang其qi轉zhuan換huan為wei無wu抖dou動dong信xin號hao，可ke以yi輸shu入ru到dao測ce量liang或huo存cun儲chu記ji錄lu儀yi。

LUYOR表示，ROLS-5PW可以在高達300000rpm的轉速下運行，這對於增壓器測量以及低速測量（取決於分析係統）也足夠用於風力渦輪機和船舶推進係統等應用。
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.
