  • Accessories

1. This instrument is a floor structure, using PC control technology, automatic temperature control, automatic timing, real-time display of the displacement, and automatically record the displacement curve, print report.

2. Simultaneous display time and displacement, time and temperature curve during the test, providing practical basis for the study of the characteristics of asphalt mixture rutting research units.

3. The instrument can be tested under the test temperature of 45 C ~ 85, wheel pressure is 0.7MPa, the standard test time is 60min.The instrument adopts high accuracy displacement sensor, The precision is more than +0.05mm .The data resolution is high and the speed is fast.

4. Using absolute temperature sensor collect temperature, PWM modulation way for temperature control, high temperature stability, no overshoot, long time test, no temperature drift(The effect of the temperature shift of the general thermocouple temperature sensor on the test data is eliminated).

5. Using high-precision A / D (16 bit), D / A (16 bit) module, ensure that the displacement measurement and temperature control accuracy and resolution. Constant temperature box adopts outer circulation heating mode, the temperature field is uniform.
