HYDRAULIC UNIT

Servo Hydraulic unit; fast loading feature and continuous high flow electric motor driven multi-piston pump, manifold with servo valve system and pressure relief valve, necessary connections and hoses and oil tank consists of.

CONTROL UNIT

Loading speed can be adjusted between 0.05 kN / sec and 30 kN / sec thanks to the “Sematron Touch V4 control unit with touch LCD. The electronic control unit has a 1000 Hz (1 kHz) data acquisition and processing capability and automatic calibration. The system has close loop loop and loading and unloading controlled experiments can be carried out on this side. In the system, sinusoidal, ramp load loading, constant load standby procedures can be performed. The electronic control unit has 4 analogue and 4 digital and 4 serial channels. Semi-dynamic applications can be performed at low frequencies and amplitudes. The sampling frequency for long-term Creep applications is adjustable.

CONTROL UNIT DISPLAY

10 inch touch capacitive display, easy-to-adjust user-friendly interface, built-in USB port to directly receive results directly from the LCD screen without using Pc and internet connection to control unit via external USB port to enable LCD control unit to communicate with computer, (optional, mini printer support and compatible with all HP printers), software update via USB, ability to save test results in excell and pdf format, print results directly from LCD (optional, mini printer support and compatible with all HP printers).

TYPE SYSTEM

4-column, 150×300 mm hydraulic loading system with fully automatic servo control consisting of loading system, mechanic spring and lockable creep system, piston and servo hydraulic power unit that can simultaneously test on 3 samples in cylindrical structure. consists of 6 absolute type position sensors and 3 compres- sion meters in order to measure the deformation on it.

CREEP TEST FRAME

After the desired load is reached, the sample is transferred to the mechanical springs in the load system by the under-table system. Thus, the loading is mechanically fixed during long-term creep tests. The body has 4 columns, welded and rigid structure. Creep test at constant load can be carried out simultaneously on 3 specimens with dimensions of 150×300 mm in cylindrical structure with load control.

LOAD MEASUREMENT

Load measurement and control is carried out with a load cell and 2% to 100% of the capacitor with class 1 or better sensitivity according to EN-ISO-7500-1 standard.

DEFORMATION MEASUREMENT FRAMES

150×300 mm in size Suitable for cylinder samples, made of light aluminum profile. 2 vertical and 1 horizontal deformation measurement sensors can be connected.
