Before being sold, all original ONIX models made at the Chelyabinsk plant are required to undergo verification. They also come with a certificate of conformity and a copy of the accreditation decision made by the State Register bodies.
Unit design
Except for the compact model 2M, standard ONIX sclerometers come with the following components:
- Spring block to ensure impact on the concrete surface. For ease of use, the tip of the block is equipped with a 4-point support, which allows you to securely install the device on any surface before starting measurements.
- Microprocessor with a wide-screen liquid crystal display for reading indicators and mode switching keys.
- Impact block and processor are connected by a cable through which the pulse signal is sent for processing before being displayed on the display.
- From the back The reader of the module is the compartment with the battery, and on the bottom – the connector for connecting the charger. There is also a socket for connecting a micro USB cable for communication with a PC.
- All electronic parts and body elements are designed for normal operation at an outside air temperature from -10 to +40 o C.
Every device comes with a handy zippered case that can be used to carry it around the facility to test load-bearing structures at various elevations when needed.
Description of the mechanism and operating principle
The ONIX sclerometers work by measuring the resistance of the material’s surface under impact in order to ascertain the hardness of the material.
The following algorithm serves as the foundation for the device’s operation:
- When impacted by a metal ball located in a spring block, the kinetic energy of the device is transferred to the concrete structure.
- Concrete has a certain hardness, as a result of which it resists impact, absorbing only part of the energy.
- The remaining energy in the form of elastic rebound is transferred back to the spring block.
- Electronic sensors record the parameters of the tested surface and transmit the information to the processor.
- The microcomputer processes the received data using a two-parameter scheme, after which the device interface displays the numerical values of concrete strength in the usual form.
The tests are conducted in multiple iterations, with the impact of the shock pulse being applied successively in multiple locations on the same surface, due to the heterogeneity and increased porosity of the material. Typically, there are spaces between neighboring control points that are between 100 and 500 mm apart.
Instructions for use for different models
Regardless of the modification, the standard sclerometer "ONIKS" is not all that different from other devices in the same class. The following actions must be taken in order to get the right measurement:
- The impact module cable is connected to the information reader.
- The device turns on by holding the power key for 2 seconds.
- The required parameters are set on the reader – units of measurement, impact load range, concrete class.
- The spring block is cocked before the impact by moving the lever on the body until the lock is triggered.
- The impact block is applied to the test structure, pressed by all 4 support points.
- By pressing the button, the spring forcefully pushes out a metal ball, which has an impact effect on the concrete surface.
- Immediately after the impact, the reader display shows the numerical values of the material"s resistance to compression in kgf/cm2, or in MPa.
- The operation is repeated for several zones on the test structure. There is no need to rewrite the values, since the device"s RAM remembers up to 50 thousand. last measurement results.
- During office processing of the results, the device is connected to a PC via a cable or via Bluetooth communication.
- With the application installed on the computer, the operator reads the readings in the form of an electronic table.
With a type 2M device, the algorithm is precisely repeated; however, this time, the impact is generated by the same device, which then shows the numerical values of the impulse rebound.
When utilizing the "ONICS-2.6" flaw detection equipment, a graphic representation of the heterogeneity of the concrete structure—which is how real flaws are identified—can also be seen on the screen.
Decoding the readings
Since the necessary conversions are carried out automatically, modern electronic sclerometers frequently display the readings on the screen already in the form of ready-made numerical values. It only takes a few easy steps to read the device’s readings:
- The main function of the metrological equipment is to establish an accurate relationship between the magnitude of the impact rebound and the strength of the concrete surface.
- If only the elastic rebound values are displayed on the screen, you must refer to the table, which is attached to the operating manual for the sclerometer.
- The graph shows the curve of the rebound in mm and the resistance of concrete in kgf/cm 2 .
- According to the actual value of the impact impulse, it is necessary to apply the ruler to the corresponding number on the abscissa axis and determine the point of intersection of the vertical line with the graph.
- Next, the ruler is applied to the intended point in the horizontal direction, until it intersects with the corresponding value on the ordinate axis.
Since the spring mechanism’s rebound value is automatically compared, most modern equipment does not require this kind of processing of the results, allowing the operator to see the concrete strength values right away on the screen.
Faults and errors
Since all modifications to the non-destructive "ONIKS" method of measuring the strength of concrete structures are high-precision devices, any errors in determining the material’s mechanical and physical properties are restricted to the tolerances specified by the manufacturer:
- The overall error of all devices in this category is +/- 2% of the obtained readings.
- In the case of operating the equipment at low or high temperatures, the manufacturer allows for the formation of an additional error within 0.5%-1%.
Any malfunction that could compromise the device’s accuracy is linked to either battery discharge or mechanical wear on the connecting cable.
Should the apparatus start generating blatantly inaccurate measurements, this could point to a malfunctioning processor. In these situations, you should get warranty repairs from the plant’s authorized dealers’ service centers.
Advantages and disadvantages
When in use, ONIX sclerometers provide users with the following indisputable benefits:
- The design of the device is based on a two-parameter algorithm for reading indicators, which allows achieving the utmost accuracy of measurements.
- The impact block has small dimensions and weight, is easy to cock and provides a concentrated impact on the concrete surface.
- The equipment can be operated with one hand, without the help of special protective equipment – the device is absolutely safe for the operator.
- If you have the skills to work with the equipment, the measurement speed is achieved up to 10-15 impacts per minute, which allows you to perform a large number of iterations and get a more accurate result.
- Electronic parts are covered with a shockproof case, reliably protecting them from dust and moisture.
- When impacted, the device does not recoil.
- Multi-point support base allows you to install the equipment on any horizontal and vertical surface, without distorting the measurement results.
In addition to their benefits, the "ONIX" devices have a few minor drawbacks as well.
