Specifications for the TKG100/TKG150 Ultrasonic
Thickness Gauges
Size:
5" (127 mm) (L) x 3" (76.2 mm) (W) x 1.25" (31.75 mm) (H)
Weight:
8 OZ (.23 kg)
Thickness range:
0.008 - 20 inches (0.20 mm - 508 mm), depending on
material, temperature and transducer selection
Material velocity calibration range:
0.200-
0.7362 in/μS (0.508
-18.699
mm/μS)
Temperature:
Gauge Operating: -4° F to 122° F (-20° C to 50° C) Surface
temperature of material: Depending on probe used, from -5° F to 1000°
F (-20° C to 537° C)
Battery life:
Up to 200 hours (40 hours with backlight on)
Battery type:
2 "AA" Alkaline
Display:
128 X 64 Graphics LCD monochrome
Information displays:
LOS, min, max, large reading while displaying min
at the same time, velocity, zero, calibration, units, freeze, unfreeze, %
battery life remaining, gain - low, std, high, echo-to-echo symbol
(option)
Resolution:
0.001" (0.01 mm), 0.01" (0.1mm)
Accuracy:
Basic Accuracy is 0.004” but on clean smooth steel an
accuracy of 0.001” is not uncommon. The more corrosive the
environment, and pitted the surface under test, the closer to the 0.004”
accuracy one can expect to be. As noted, a higher accuracy can be
obtained when measuring on cleaner steel.
Probe recognition:
Via pick list from a menu
Delay line zero measurement:
Auto at power up with listed numeric
value. Ideal for correcting delay line wear/curvature and for transducer
acoustic drift at elevated temperatures
Package:
Custom, splash-proof, high-impact plastic with rubber,
illuminating keypad for go/no-go testing
Bandwidth:
0.5-20 MHz (-3dB)
Units:
English/Metric/Microseconds
Gain:
Low, Standard and High for varying test conditions
Measurement rate:
4/sec and 20/sec in fast mode
