  • Page 8: Introduction

    50 µm. 1.3 Measuring Procedure The working principle of QuintSonic 7 is based on the reflection of ultrasonic waves at the interfaces between the individual layers of a coating system. For measurement, a liquid or pasty couplant is applied on the sample at the point of measurement. The sensor is put on the measuring spot.

    For processing a signal emitted by an ultrasonic sensor, an appropriate reference signal is required. QuintSonic 7 autonomously checks the validity of the existing reference signal. If the reference signal is invalid, you will be asked to take a new reference signal (see screenshot below).

  • Page 42: Selecting A Couplant

    Main target is to ensure both, a maximum input of energy as well as a maximum output of energy (of the receiving signal). For this purpose, the couplant must feature appropriate acoustic properties. © ElektroPhysik QuintSonic 7 42 von 184...

  • Page 43: Checking / Carrying Out Calibration

    The suitability of the above listed couplants for this application has been carefully checked and approved by ElektroPhysik. If other couplants are used, user is responsible for measuring errors or damage to the sensor. Please note that any warranty claim will expire if the sensor is damaged by use of couplants other than those approved by ElektroPhysik.

  • Page 44: Taking Readings

    After measurement and if you want to take the gauge out of service, use a moist and soft cloth for cleaning the sensor surface. Dried up residue of couplant on the sensor is hard to remove and the sensor might be damaged when trying to clean from such residue. © ElektroPhysik QuintSonic 7 44 von 184...

  • Page 45: Measuring Procedure

    When taking repetitive measurements on the same spot, take care of the state of couplant. It must not dry up. If necessary, remove the used couplant and apply a new quantity. Make sure the couplant is evenly distributed over the measuring surface. © ElektroPhysik QuintSonic 7 45 von 184...
