Large Platform Full Automatic Rockwell Hardness Tester MHRS-150-Z

Large Platform Full Automatic Rockwell Hardness Tester MHRSS-150/45-Zr, adopted the international advanced closed-loop sensor control technology, to achieve full automatic control and hardness testing process. The load system uses high-precision force value sensor and central controller to form a closed-loop loop to achieve full microsecond level tracking and control of the booster process.

The measurement system uses Japanese high-precision displacement sensor with a hardness value resolution of 0.1 HR and an accuracy of ± 0.15 HR. The position of the indenter is fixed, and the hardness test is carried out by moving up and down the platform. The overall movement of the large platform eliminates the gap generated during the lifting and lifting of the wire bar, greatly improves the accuracy and repeatability of the test, and also increases the stability and efficiency of the machine's work. Add foot switch function, a key type of measurement, saving a lot of manpower, convenient for use in the field.

Set up special management device for displacement sensor QEI

The original motherboard has no dedicated management device, and the CPU must continuously process the displacement sensor signal in person throughout the loading process.

After setting up a dedicated management device, the CPU only needs to read the data at the beginning and the end of the two time points. The CPU of the loading process can concentrate on the resource management force sensor and the loading motor, making the control faster and more accurate.

Introduction of Japanese High Precision Magnetic Grid Displacement Sensor

The original displacement sensor is a domestic grating displacement sensor. There is a lack of consistency, and it is necessary to match the equipment with other problems.

The Japanese high-precision displacement sensor has high consistency and is less affected by the environment. The life span can reach more than 150 million times.

The loading process of the traditional Rockwell loading process is slow. If the loading speed is to be controlled within the 8 seconds required by the national standard GBT230/T -91, In the figure, the red curve continues to overshoot and dismount at the total test force F to approach the total F phenomenon. The result of this is that the hardness meter must slow down the test speed, causing the detection time to be too long; Second, the overcharging phenomenon affects the test accuracy to a certain extent.

The device adopts a more advanced and suitable central processing chip to respond to the entire hardness test process at high speed. After each hardness test is started to the end, the central processing chip will process 18,000 to 30,000 sets of data at super high speed. Shorten the load action that the traditional electric charging hardness meter takes 8 seconds to achieve to 2 seconds. The blue curve in the figure shows that the speed of the loading process reaches a speed, and the force value is smooth and inrush during loading to the total test force, which improves the loading speed and accuracy of the electric charging hardness meter.
