Often people use a pendulum protractor to determine the angle of the cutting tool. The measuring device greatly facilitates the work of a person. It is suitable for different types of tools. The pendulum protractor is called ZURI, sometimes the designation ZURI-M is found. The device is classified as a mechanical type device.
The principle of operation of the pendulum protractor
This measuring device works according to the principle of the mass of the pendulum, which is directly connected to the indicating arrow. The device has a common axis of rotation with an arrow.
How are the rotation angles measured?
On the dial of the pendulum protractor there are divisions. The angles of rotation of the pendulum are counted on them. When you need to take measurements, the control ruler touches the surface of the used cutting tool. In the pendulum goniometer ZURI there is a special locking device for the position of the arrow.
Technical characteristics of ZURI
ZURI measuring device differs from other measuring devices in its technical characteristics:
- The desired device has a measurement range from 0 to 360 degrees.
- The scale mark is one degree.
- Overall dimensions do not exceed 100 by 20 by 90 millimeters.
- Relative humidity is 80 percent.
- Pressure varies from 84 to 106 KPA.
- The service life of the device is five years. Much depends on the intensity of operation and on compliance with its rules. When using the protractor, it is not recommended to drop it. Blows to him are also contraindicated. Otherwise, the measurement data will not be accurate. The error in such a device can be up to one dozen degrees, which is very significant.
How to convert minutes to degrees on a goniometer?
Many people wonder how to use the goniometer. This is really very important. The result of work depends on the proper use of the device. Often people do not know how to correctly convert minutes to degrees. The number of divisions of the protractor is correlated with the corresponding degree measure. For convenience, you can use the following values:
Total divisions of the goniometer | 60 | thirty | fifteen | 10 | 1 |
Corresponding value in degrees | 360 degrees | 180 degrees | 90 degrees | 60 degrees | 6 degrees |
A calculator is quite suitable for translation.
Where is the goniometer used?
This device is mainly used in industrial sectors. In this area, accuracy must be observed. The pendulum goniometer is often used in industries where other measuring instruments cannot be used.
The goniometer is also indispensable in factories producing various tools. ZURI device is used in construction. It is suitable for multi-plane operation.
Pros and Cons of Using
The pendulum goniometer has the following advantages:
- It is a universal measuring device.
- You can work with it in the vertical plane, as well as in the horizontal.
- The device is quite simple to operate. It greatly facilitates the work of masters.
- Two types of measurements can be carried out using one instrument.
- The goniometer has a low error. You can get reliable information that will be important in future work.
- The device weighs little. It is convenient to carry.
- The goniometer can be used in hard to reach places.
- Wide measuring range. It is up to 360 degrees. It can be used in various fields.
Disadvantages of the pendulum protractor:
- It cannot be used for small parts.
- The appliance is not suitable for use in cold weather. It can only be used indoors.
As we can see, the device does not have any special drawbacks, and therefore is indispensable for measuring work in many areas of industry and production.
