Ultrasonic thickness gauge A&B Scan for testing rubber
thickness TM281
Product Description:
TM281 Series Color Screen with A/B-Scan Ultrasonic Thickness Gauge
Professional in Solving Various Difficult Thickness Measurement
Features:
2.4” color OLED, 320 X 240 pixels, contrast 10,000:1
Live Color A-Scan
Users could directly see the color waveform of the ultrasonic sound
(or A-scan) on the screen, which is quite important for the
occasions that we need to check the correctness of the testing
results. Many cases will cause wrong testing results or even
noreadings. We could find the causes easily through the A-scan.
Adjust the three parameters of GAIN, BLACKING, GATE, and then we
will get the right readings.
Live Color B-Scan
TM281 series thickness gauge has time base B-scan function. Move
the probe along the workpiece surface, then the cross -sectional
profile of the workpiece display, use for observe the underside
contour of the workpiece.It could be automatically capture a
minimum value of the B-scan image, and indicate the position of the
minimum by a red triangle. You can see any point thickness value of
the B-scan image by moving the pointer.
Through Coating Function No longer need to waste time to remove the coating
Now TM281D and TM281DL also have this widely acclaimed function.
It's realized by measuring the two continuous bottom surface of the
substrate. This mode also has more advantages:
- Exempt Zero Calibration
- High Stability, the measuring value is not influenced by the probe
pressure, the coupling layer thickness and the surface dust of the
workpiece.
- Zero Drift
More Practical Function :
Difference/Reduction Rate: Difference mode displays the difference between the actual value
and the normal value. Reduction rate calculates and shows the
percentage of the thickness reduction when the material becomes
thin. Typical application is to measure the metal material which is
due to bending and becomes thin.
Max./Min. Capture: On this mode, the current thickness, minimum thickness and the
maximum thickness will be shown on the screen at the same time.
Alarm Mode: Dynamic change the color of thickness readings when alarming.
Update Rate: Selectable 4Hz, 8hz and 16Hz. 4Hz for ordinary application, when
you need a quick scan, such as high temperature measurement, you
can choose higher update frequency.
Multi- Languages Available: Chinese, English, Japanese, French, German.
Standard TC510 Probe:
The probe is the heart of the instrument,TMTeck has the world’s
leading probe production technology. TC510 probe uses the high
performance piezoelectric ceramic chip, with integrated metal
die-casting shell, practical design of probe and cable separated,
regardless of costs to create high quality .
