Measuring equipment covers more and more areas of application - from domestic segments to specialized areas in construction. In particular, it can be handheld devices, and massive multifunctional equipment that supports several measurement parameters at once. A special place on the market is occupied by an ultrasonic thickness gauge A1209, the list of tasks of which includes scanning the surface coating without destroying its structure. The device is small in size, but in terms of functionality it surpasses many professional devices that also measure with non-destructive testing.
Model Overview
The model is a compact device designed to determine the thickness of walls, coatings, vessels, boilers and parameters of various products made of metal. It is also worth noting the ability to connect the converter to the A1209 device. An ultrasonic thickness gauge, the photo of which is presented above, shows an example of combination with a complete signal converter. The addition of this device provides the ability to obtain more accurate information, and also opens up the possibility of working with corroded surfaces.
Special transducer models for servicing surfaces heated to 250 ° C are also included. Also for full operation, the device is equipped with a network adapter, a disk with software, a USB cable and an electronic unit. It is important to note the form factor in which this ultrasonic thickness gauge is made. Description A1209 can be represented as follows: a classic manual device for measuring thickness, complemented by mechanical controls, connectors for integrating sensitive elements and a display.
Specifications
With small dimensions, the device provides average performance and accuracy by the standards of a professional apparatus. The developers balanced the model in terms of technical and structural parameters, and ergonomic qualities. As a result, the A1209 tool turned out to be convenient and comfortable in operation. The characteristics of the ultrasonic thickness gauge of this modification can be represented as follows:
- The range of working thickness is from 0.07 to 30 cm.
- Measurement resolution - 0.1 and 0.01 mm depending on the measuring range.
- The measurement error is from 0.01 to 0.05 mm, depending on the thickness of the product.
- The speed range of ultrasound is from 500 to 20,000 m / s.
- Voltage - 3.7 V.
- The temperature regime for using the device is from -20 ° to +50 ° .
- Display type - color TFT with anti-reflective coating.
- The battery life is 9 hours.
- The dimensions of the device are 161x24x70 mm.
- Mass - 210 g.
Device features
The principle of operation of the device, which is based on a double echo pulse passing an acoustic signal through an object, is not innovative by today's standards. The developers singled out this model from the general series of similar devices by increasing accuracy and an additional option. As for accuracy, it was improved thanks to a proprietary system for adapting the device to surface imperfections. That is, the apparatus automatically calculates the curvature and roughness of the target product, makes the appropriate correction, and only after that implements the final scan. An additional option also distinguishes the A1209 model from the general segment. An ultrasonic thickness gauge with memory is equipped with a USB cable as standard, allowing it to be connected to a computer. The information recorded during operation in the device memory can be transferred to a PC and processed using special software. By the way, non-volatile memory allows you to store up to 50,000 measurements.
Device calibration
Before you start working with a thickness gauge, you should calibrate it. It is recommended to do this procedure every time after changing the converter, after changing the conditions of use and radically updating the settings. To start the calibration procedure, you must click on the button of the probe testing process. This mode will open automatically after changing the inverter. After this, the adaptation stage A1209 begins. The ultrasonic thickness gauge will be reconfigured to new operating parameters under conditions of automatic performance analysis. The calibration stage ends with a test supply of an echo signal, the processing of which will be carried out using an adjustment sample. This will make it possible to determine the accuracy of the data obtained with high accuracy.
User's manual
The device can be used in conditions of temperature from -20 ° to +50 ° , while the humidity coefficient should be up to 85%. Just before work, both the device itself with the transducers and the working surface must be cleaned. In the process of measurement, it is undesirable to slide the device along the working surface. If you plan to measure the surface over a large area, you should arrange the transducers in different areas of the test coating to improve the accuracy of the A1209 ultrasonic thickness gauge. The instruction also indicates the peculiarity of the approach to working with local point measurement sites. In such places, to improve scanning accuracy, it is recommended to use a converter with contact clean grease. Also, during the examination, it is worth remembering about the battery charge. Reducing its energy reserve to the minimum limits can affect the quality of the device.
Instrument Operation Modes
The basic mode is called “Norma”. In this state, the device can perform thickness measurements, control the functions of indicators and present fixed data to the display. The next mode is Memory. This is the mode of setting information saving parameters. The user can create different groups to save data, as well as edit specific records that the A1209 device registered. The ultrasonic thickness gauge also provides extensive options for setting up work with transducers. For this, the “Settings” mode is intended. It can also be used to adjust in detail the data storage parameters, power supply conditions, etc.
Product reviews
According to users, the thickness gauge was successfully made in terms of ergonomics and functionality. By the general standards of the line of its manufacturer, it has average working qualities, but operating practice shows that, within the framework of the basic capabilities, the device fully meets the stated requirements. Separately, the universality of the A1209 model is noted. The ultrasonic thickness gauge in the basic configuration is supplemented by several transducers, which simplifies the work with problematic surfaces and the control of heated objects. As for the shortcomings, measuring devices of this type rarely cost more than 50-60 thousand rubles. In this case, the price tag exceeds 80 thousand, which, however, can be explained including rich equipment.
Conclusion
The device is a solid solution for companies that are engaged in the maintenance of engineering and construction projects. With it, the operator will be able to check the thickness of the communication line, mounting structure or production workpiece. Both cost and technical specifications indicate the professional level of the A1209 ultrasonic thickness gauge. The manufacturer of this model is the company “Acoustic control systems”. This company is not the first year working on the creation of modern means of non-destructive testing. In general, its products have a positive reputation in various fields of application. As for the A1209 model specifically, it represents the middle class of an ultrasonic thickness gauge, the capabilities of which can be considered as an effective base for performing universal measuring operations. Of course, this option will not be needed for home use, but it can provide significant metrological support to professional construction organizations.
