Ultrasonic Sheet Strength Tester (SST-4000)

SST measures propagation speed of supersonic pulse in 16 directions (11.25 degree each) with 8 pairs of transmitter/sensor in the sheet, and calculates tow power of velocity V (km/s) of
each direction. Since V2 is very good correlating with 'Young's modulus', SST defines Tensile Stiffness Index "TSI = V2" and
calculates TSI of the machine direction ''TSlmd" and of the cross direction "TSlcd".
Also SST calculates Tensile Stiffness Orientation angles for maximum TSI direction "TSOpeak" and for minimum TSI direction "TSOdeep".
All measuring operation and data analysis are performed through a screen and a keyboard of a WindowsXP laptop PC.

Single sheet of A4 size (21 x 29.7 cm) or similar size is suitable for "SINGLE SHEET" measurement.
All key measured values and an oval graph are displayed in 15 seconds after measurement.
CD profile measurement can be done with an optional automatic feeding device. The profile is shown on the screen. Measuring interval is selectable between 10 and 1000mm.
Long MD sample is also measurable with an optional automatic feeding device showing the result on the screen.
Interval between 10mm and 1000mm is selectable, and maximum measuring point is 65000.
