ACS UK1401 SURFER – Ultrasonic Pulse Velocity Tester (UPVT)

Alat uji kecepatan pulsa ultrasonik yang ringkas, ergonomis, dan mudah digenggam untuk inspeksi beton.

Perangkat ini terbuat dari plastik ringan yang tahan benturan dan dilengkapi dengan dua transduser bawaan dengan dry-point-contact serta basis tetap (150 mm). Ujung transduser yang tahan aus tidak terpengaruh oleh kondisi permukaan, sehingga tidak memerlukan gel kopling atau persiapan permukaan sebelum pengukuran.

Deskripsi

Alat uji kecepatan pulsa ultrasonik yang ringkas, ergonomis, dan mudah digenggam untuk pengujian kualitas beton.

Alat ini juga dilengkapi dengan indikasi suara saat sinyal ultrasonik diterima, serta memori non-volatile yang dapat menyimpan hingga 50.000 pengukuran (dengan fitur pengelompokan data). Selain itu, perangkat ini memiliki port USB untuk mentransfer data hasil pengukuran ke PC eksternal.

Aplikasi

Evaluation of the durability of concrete. The evaluation is based on correlation between time of propagation/velocity of longitudinal ultrasonic waves in concrete. Measurements are performed by the surface scanning with a fixed base.
Search for near-surface flaws in the concrete structures by abnormal decreasing of ultrasound velocity or increasing of the propagation time in the flaw area.
Evaluation of anisotropy in composite materials.
Evaluation of concrete curing during building of poured-in-place concrete method and sliding shuttering.
Evaluation of the load-carrying ability of concrete backbones and posts.
Evaluation of the depth of the outcrop cracks.
Evaluation of porosity and fissuring of the material.
Evaluation of the age of material if its physical properties change with time.
