Portable Ultrasonic Flaw Detector JV-MFD500

Alat Uji keretakan merupakan alat uji untuk mengukur retakan baik kedalaman maupun lebar keretakan. Dalam beberapa bidang diantaranya alat uji keretakan dirancang untuk mendeteksi ada tidaknya kecacatan (flaw).

Salah satunya dengan cara menggunakan deteksi suara (ultrasound) yang dapat mendeteksi saat material tersebut diuji.Retak sendiri didefinisikan sebagai dari satu kesatuan yang rusak dan membentuk garis terbelah pada material tertentu dan dapat menjadi indikator ketidak sempurnaan suatu material yang dapat mempengaruhi kualitas dan kekuatan produk material itu sendiri.

Alat Uji keretakan digunakan sebagai alat yang dapat memberikan data informasi nilai dari retakan yang terjadi, sehingga data dapat digunakan untuk kepentingan analisa kualitas dan kekuatan material sehingga pengguna dapat menentukan standar yang diinginkan.

• Rectification: Positive half wave, negative halfwave, full wave, and RF DB Step: 0dB, 0.1 dB, 2dB, 6dB step value as well as auto-gain mode


• ALARM: Alarm with sound and light

MEMORY: Total 100 configuration channels store all instrument operating parameters plus DAC/AVG curve; stored configuration data can be easily previewed and recalled for quick, repeatable instrument setup. Total 1000 datasets store all instrument operating parameters plus A-scan. All the configuration channels and datasets can be transferred to PC via USB port.

FUNCTIONS:

• Peak Hold: Automatically searching the peak wave inside the gate and hold it on the display.


• Equivalent diameter calculation: find out the peak echo and calculate its equivalent diameter.


• Continuous Record: Record the display continuously and save it to the memory inside the instrument.


• Defect Localization: Localize the defect position, including the distance, the depth and its plane projection distance.


• Defect Sizing: calculate the defect size


• Defect Evaluation: Evaluate the defect by echo envelope


• DAC: Distance Amplitude Correction


• AVG: Distance Gain Size curve function


• Crack measure: Measure and calculate the crack depth
