TPCT-5A wheel tracking machine


STANDARD: EN 12697-22

Features:

1. It can be used as water immersion test.

2. It can test 2 specimens at the same time.

3. Automatic temperature control, automatic generation and save the test results, Convenient call history data, output test report.

4. Point to point data collection: the position of the upper and lower machine control system to ensure the deformation repetitive gathering space.

5. High resolution data acquisition, high speed.

6. Wiide temperature range, high precision, good stability, PWM modulation method is adopted to improve the temperature PID control, to ensure that the temperature without overshoot.

7. Using absolute temperature sensor to collect temperature, test without temperature drift for a long time (to eliminate the general thermocouple temperature sensor working temperature drift for a long time) on the test data.

8. Air circulation in the oven, high temperature control precision.

9. Displacement sensor with high precision, under the big range accuracy is less than + / - 0.05 mm.

10 Equipped with constant temperature box integration structure, easy to move.

11. Smooth operation, no noisy.

12. Available computer with touch screen independently control (optional).

13. Can preheat six test at the same time. 14. Small volume, covers an area of only 1.52 m × 1.1 m.


Software Features:

1. It can be set arbitrary time and temperature.

2.Real-time display time, temperature, displacement deformation and time curve.

3. It can display time and number of RCC.

4. Automatic calculation and print the rut dynamic stability.

5. Software for displacement sensor and temperature sensor calibration precision.

6. Self-diagnosis function, and can display the fault code, to ensure reliable operation.

7. Multipoint sampling on the deformation and improve the consistency of the experimental results.
