Often, people use a pendulum goniometer to determine the angle of a cutting tool. The measuring device greatly facilitates the work of a person. It is suitable for various types of instruments. The pendulum goniometer is called ZURI, sometimes the designation ZURI-M is found. The device is classified as a mechanical device.
The principle of operation of the pendulum goniometer
This measuring device works on the principle of the mass of the pendulum, which is directly connected to the pointing hand. The device has a common axis of rotation with an arrow.
How are rotation angles calculated correctly?
There are divisions on the circular scale of the pendulum goniometer. According to them, the angles of rotation of the pendulum are counted. When measurements are to be taken, the reference ruler touches the surface of the cutting tool being used. The ZURI pendulum goniometer has a special locking device for the position of the arrow.
Specifications ZURI
Measuring device ZURIdiffers from other measuring instruments in its technical characteristics:
- The desired device has a measurement range from 0 to 360 degrees.
- The price of the scale division is one degree.
- Dimensions do not exceed 100 by 20 by 90 millimeters.
- The relative humidity is 80 percent.
- Pressure ranges from 84 to 106 kPa.
- The service life of the device is five years. Much depends on the intensity of operation and compliance with its rules. While using the protractor, it is not recommended to drop it. Hitting him is also contraindicated. Otherwise, the measurement data will not be accurate. The error of 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 the work depends on the correct use of the device. Often people do not know how to correctly convert minutes to degrees. The number of divisions of the goniometer is correlated with the corresponding degree measure. For convenience, you can use the following values:
| Total goniometer divisions | 60 | 30 | 15 | 10 | 1 |
| Corresponding value in degrees | 360 degrees | 180 degrees | 90 degrees | 60 degrees | 6degrees |
A calculator is fine for transferring.
Where is the goniometer used?
This device is mainly used in industrial sectors. In this area, measurement accuracy is required. The pendulum protractor is often used in industries where other measuring instruments cannot be used.
Protractor is also indispensable in factories producing various tools. The ZURI device is used in construction. It is suitable for working in multiple planes.
Pros and cons of using
The pendulum protractor has the following advantages:
- It is a universal measuring instrument.
- It can be used vertically as well as horizontally.
- The device is quite easy to operate. It greatly facilitates the work of the masters.
- Two types of measurements can be made with one instrument.
- Protractor 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.
- Protractor can be used in hard-to-reach places.
- Wide measuring range. It is up to 360 degrees. Can be used in various fields.
Disadvantages of pendulum goniometer:
- It cannot be used for small parts.
- The device is not suitable for use in cold weather. It can only be used indoors.
As we can see, the devicehas no special drawbacks, and therefore is indispensable for measuring work in many areas of industry and production.
