Adopting brand PC to control high precision hydraulic servo valve to drive hydraulic cylinder to realize such operations: parameters setting, data acquisition, processing and analysis, display, results print, setting the loading speed arbitrarily, control of loading rate, hold time, cyclic loading, etc.
With automatic stop function when specimen breaks(among them,destructive test for HT materials; cyclic, deformation and destructive tests for QT materials).
Comply with European standard EN124.
1) Max. Test force£º 1250kN
2) Measuring range of test force: 1%-100%FS
3) precision of test force: better than ¡À1%
4) adjusting range of test force speed:0.5¡«10kN/S
5) max. Piston stroke: more than 250mm
6) compression test space: 0¡«350mm
7) size of upper loading nose£º ¦µ250x40mm
8) protection function£ºAutomatic stop when exceeding 2%-5% of max. test force
9) it is automatic loading or un-loading by PC 12) the releasing speed of pressure: more than100kN/s
10)it can display loading ,automatic record peak value, adjusting the system error.
11)it can be measure displacement (loading from 0- Max ) precision 0.1mm
16)it can be measure deflection from underside of table geometric center, range
