Length and speed measurement gauge

摘要

The LaserSpeed~® 4000 length and speed measurement gauge uses Laser Doppler Velocimetry technology to measure the length and speed of any moving surface to an accuracy of +/-0.05 percent. This non-contact gauge also features Ethernet communication and configurable I/O for easy integration into any control or monitoring system. These were designed to be drop-in replacements for any type of mechanical tachometer.
