Hydraulic system
It is an hydraulic installation and has a high performance valve directly controlled by the digital unit that grants the automatic control of the pace rate increasing the load, keeps a certain load and than controls the pace rate decreasing the load.
The setting of the pace rate is regulated by a very sensitive valve controlled by a step by step motor that allows a micrometric action on the pace rate granting excellent results in the control of the load. A laser position detector allows a rapid positioning of the piston and a very accurate touch point. This grants a touching sensitivity of test starting of about 0.1 per thousand of the maximum capacity. When used in conjunction with the C104NLP for the application of the side pressure, the hydraulic system permits to maintain the pre-load level with extremely high accuracy.
Electronic measuring system
The high performance control and data processing unit controlled by a 32 bit microprocessor can manage up to 8 high resolution channels for the control of load cells or transducers with strain gages bridge.
The unit contains two Analogical/Digital last generation converters with 24 bits resolution. The system processes the signals coming from the load cells and from the extensometers giving all the results required for a further processing following the most updated standards for this application.
Data acquisition and processing software UTM2 (Universal Testing machine 2) with License for Elastic Modulus on Rocks
The software has been developed on the working line of the already known software UTM-2 (windows menu). It contains the profiles of the main Standards used, but the user can modify and personalise the test profile, which will be effected in a completely automatic way by the testing machine.
