Sensitivity of the ultrasonic flaw detector, for weld inspection

Sensitivity of the ultrasonic flaw detector

Detection sensitivity determines detection ability.

High detection sensitivity is good for detection, but very high sensitivity will make much noise wave and affect the precision, the Lack detection sensitivity will result in lower ability and miss defects.

In flaw detection, gain adjustment can be used to control the sensitivity of the instrument, measure the relative height of the signal, determine the size of the defect or measure the attenuation performance of the material, etc. Unit: dB. the gain adjustment of the flaw detector can be made simply by press the easy button.

sensitivity Leavings: more 50dB (for Deep 200mmФ2 flat-bottomed hole - this is a calibration block), the gain is adjustable, the ultrasonic flaw detector KUT680 sensitivity Gain：0 dB to 110 dB adjustable in selectable steps 0.1 dB, 2 dB, 6 dB.

How to set DB offset when you built curve? Surface compensation gain (DB Offset) refers to the compensation for flaw detection sensitivity due to the influence of the surface roughness of the workpiece. Adjustment range: -30dB ~ 50dB
