激光转速探头简化了转速测量

LUYOR推出ROLS-5PW型激光转速测量探头，该激光转速测量探头可以使高速旋转机械的测试更安全、更简单方便。激光转速传感器ROLS-5PW用于旋转机械非接触式转速测量，测量范围为0RPM至300,000 RPM。激光转速监测传感器适用于风力发电机或船舶推进器之类的极低转速测量，以及增压器之类的ji高转速测量。工作距离为可达7米。

ROLS-5PW激光转速探头是一款小巧坚固的IP60级激光转速测量传感器，用于对旋转或往复式机器部件进行非接触式速度测量，通过机器元件反射的激光的传感器每次旋转产生电压脉冲来工作。激光转速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，可以输入到测量仪表或存储记录仪。

使用反射胶带意味着激光转速传感器ROLS-5PW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工程机械等各种测试对象。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 公司的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（取决于数据分析系统）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.
