ACOUSTIC CONTROL SYSTEMS Ultrasonic thickness gauge A1208 1.3 ARRANGEMENT AND OPERATION 1.3.1 Arrangement Figure 1 The thickness gauge consists of an electronic block (Figure 1) with replaceable piezoelectric transducers. The device is connected using cables. The colour TFT display is located in the upper part of the indication panel of the electronic block. It is used to display the measurement results and current information necessary to control the thickness gauge. The display enables to monitor the measurement process visually by means of color-coded indication. Under the display there...

Ultrasonic thickness gauge A1208 ACOUSTIC CONTROL SYSTEMS 1.3.2 Operating principle The operating principle of the А1208 thickness gauge mainly includes the measurement of time needed for the ultrasonic waves to pass the tested object from one surface to another and the subsequent conversion of the measured values into the thickness parameter. An ultrasonic transducer is used to emit the ultrasonic pulses into the TO and receive their reflections. The US transducer is placed on the surface of the TO where the thickness shall be measured. The ultrasonic transducer has a sharp emitting and...

Ultrasonic thickness gauge A1208 ACOUSTIC CONTROL SYSTEMS 1.3.5 The device keyboard The keyboard of the thickness gauge (Figure 9) contains 11 functional keys and the ON/OFF key. The main key functions: The ON/OFF key is used to switch the device on and off. NOTE: IF NO KEY IS PRESSED AND NO MEASUREMENT IS PERFORMED WITHIN 10 MINUTES, THE DEVICE IS AUTOMATICALLY SWITCHED OFF. NOTE: IF NO KEY IS PRESSED AND NO MEASUREMENT IS PERFORMED WITHIN 2 MINUTES, THE SCREEN BRIGHTNESS IS AUTOMATICALLY REDUCED TO THE MINIMUM VALUE OF 20 %! The functional keys (F) carry out various actions, depending on...

ACOUSTIC CONTROL SYSTEMS Ultrasonic thickness gauge A1208 The device is intended for operation under the environmental conditions specified in the Section 1.1.2. 2.2 PREPARING THE DEVICE FOR USE 2.2.1 Preparation of the surface Please clean the surface of the object to be tested, remove all dirt and sand and any corrosion, also remove all loose rust and put more liquid than in case of a smooth surface. Cleaning of the rough corroded surface allows to prolong the transducer service life and to increase the measurement accuracy. To define the thickness of the object to be tested...
