Gravate -type sensor (OpticalGratingtransducer) refers to the sensor that measures displacement with the principle of raid grid stripes.The grating is a parallel parallel -parallel -parallel carvings on a long strip -shaped optical glass, with the density of the carvings of 10 to 100 lines/mm.The stacking stripes formed by the grating have optical magnification and the average effect of error, so it can improve the measurement accuracy.
Grav sensor installation
When installing the grating sensor, you must first consider the installation environment. The condition that the possibility of the grating sensor may be generated during the work of the machine is included in the consider range before determining its installation position.Generally, the main light grid ruler of the grating sensor is installed on the motion component of the machine, and the reading device of the grating sensor is installed on a fixed component.This is just a way of installation commonly used by people. If you want to change this installation method, as long as your installation is feasible, it is okay.
Grav sensor advantages
1. This sensor has a very good ability to resist electromagnetic interference, which can complete the measurement of various aspects very smoothly.2. The electrical insulation performance of the fiber grating sensor is very high -quality. It is relatively safe and reliable in use, and it does not require any other power to drive. ThereforeUse in products, such as gasoline and chemical companies.
Grav sensor price
The general price is about 160 yuan, and the price on the market may be a bit different.
Application of grating sensor
It has been more than two hundred years since the foundation of the grating. In 1978, a group of researchers in a communication research center in Ottawa, Canada for the first time in the optical fiber mixed with vermiculite.A magical effect, light sensitivity effect.After discovering this effect, it was written by the stationed waves at the time and made into the worlds first grating.After the nineteenth century, the side writing technology of a technical research center in the United States was precisely because of the unremitting efforts of these scientists that the grating technology made great progress.At the same time, with the continuous progress of science and technology, the manufacturing technology of grating is also continuously improved, and the application of various fields is also popular.
The working principle of the grating sensor
When indicating that the grating is slowly moving, the tape grating of the sensor will produce stacked grid stripes.The characteristics of this stack of grid stripes are distributed in accordance with the laws of sine, and these stripes will appear bright and dark.
