TKG150 Digital Ultrasonic Thickness Gauge/Datalogger by Extech
Extech offers Thickness Gauges designed in compact, handheld, rugged housing ideal for field use. The ultrasonic technology allows for non-destructive thickness measurements for primarily steel structures. Select models with digital thickness readout or live color waveform and datalogging function.
Features
- Wide measurement range: 5MHz probe: 0.040" to 20" of steel; 10MHz probe: 0.020" to 20" of steel (optional)
- Sunlight readable dot-matrix display with backlight
- Multiple transducer options for high temperature and difficult to measure materials
- Fast minimum feature to capture minimum thicknesses
- On screen display of 8 languages
- Splash-proof (IP54), high impact, compact housing
- Echo to Echo option to reduce coating errors
- 100K internal datalogger with export to Excel
- B-scan (visual cross section of test piece)
- Vibrate on alarm
Applications
- Boiler Tubes
- Pressure Vessels
- Storage Tanks
- Ship Hulls
- Containers
- Home Oil Tanks
- Pipes
- Steam Lines
- Compressors
- Shafts
- Bridge Pins
- Bond Inspection
| 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 |
| Differential Mode | Displays the difference from the actual thickness measurement and a user entered reference value |
| Alarms | Minimum/Maximum depth, vibralarm, audible/visual indications as well as keypad illumination |
| Illuminating keypad | F1 = Red, F2 = Yellow and F3 = Green for easy, go/no-go testing (Patent Pending) |
| Automatic probe wear indicator ( Transducer attendant) | Automatically informs the operator to replace the transducer (Patent Pending) |
| Ergonomics | User selectable left-handed or right-handed display changes via keypad (Patent Pending) |
| Backlight | Light Emitting Diode, On/Off or Auto ON based on valid readings or last key-press |
| Shut off | Auto, time out (after X minutes user programmable after no reading, loss of signal LOS, or no key press) |
| Scan mode | Displays minimum or maximum thickness value at 20 measurements per second (ideal for high temperature thickness reading and tracking the minimum depth alarm). Press Freeze to capture last valid minimum thickness readings prior to Loss of Signal (LOS), without reading the couplant upon lifting probe off the test piece |
| Carrying case | Custom molded pouch with wrist strap for either left- handed or right-handed operators (optional) |
| Shipping case | Hard plastic with high-density molded cut out for all accessories (optional) |
| Freeze mode | Freezes display |
| Hold mode | Holds display to retain last thickness reading in reverse video display |
| Standard TKG includes | Ultrasonic thickness gauge, DK-537 potted, 5 MHz 0.375 inch diameter, operational manual, cable, couplant |
| Warranty | Limited 2 year warranty |
