Structural features of the RM-25M
Tearing machine RM-25M is a test rig, which consists of a two-cylinder loading device and pump. The devices are equipped with the RM-25M modernized grips with hydraulic specimen grips for easy handling with the car and improves its performance.
Tearing machine RM-25M is equipped with a modern digital measuring system ASTM-Digital "Standard", which provides an indication of the applied force and the speed of loading of samples, as well as the fixing of the maximum load.
Tensile testing machines RM-25M in their work allow the following error:
- When measuring the load - ± 1%;
- While maintaining the speed of loading - ± 20% of the measured value.
The unit price of the least significant digit siloizmeritelej device RM-25M is 0.01 kN. Working stroke of the active capture - at least 150mm. The range of loading rates - 0.2 kN / s - 25kN / s.
In tensile testing machine RM-25M greatest distance between the supports by the bending test is not less than 160 mm, and the length of rollers - 60mm.
Tearing machine RM-25M uses a mains voltage of 380 V and a frequency of 50 Hz, and the device power consumption is less than 1.5 kW.
