激光转速探头简化了转速测量

LUYOR正在推出ROLS-5PW型激光测速探头，该激光转速探头可以使高速旋转机械的测试更安全、更简单。

ROLS-5PW激光转速探头是一款小巧坚固的IP60级激光转速传感器，用于对旋转或往复式机器部件进行非接触式速度测量，通过机器元件的每次旋转产生电压脉冲来工作。探头的位置使其可见激光束面向测试对象，测试对象上贴有一小条自粘镜反射胶带。然后，该反光贴纸将激光能量反向散射到接收器，接收器将其转换为无抖动信号，可以输入到测量或存储记录仪。

使用反射胶带意味着探头可以放置在距离测试对象7米的地方，因此工程师在测试许多不同类型的高速机械时可以保持安全距离，包括从飞机涡轮机到洗衣机等各种测试对象。该装置的紧凑尺寸也使其适用于访问包含在受限区域内的机器部件。

LUYOR表示，ROLS-5PW可以在高达300000rpm的转速下运行，这对于增压器测量以及低速测量（取决于分析系统）也足够用于风力涡轮机和船舶推进系统等应用。

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.
