Compression Testing Machine, Servo Valve Control
Request a Quote
HCT-A Series (600kN-3000kN)
The compression testing machine uses a servo valve for precise closed-loop control of force, displacement, and deformation.This configuration supports evaluation of compressive strength, elastic modulus, and Poisson’s ratio for cement, concrete, and rock specimens.
With appropriate fixtures and measurement accessories, the setup also performs concrete splitting tests and static modulus tests.
Standards
CS1, ASTM C39, ASTM C109, AASHTO T22, GB/T 50081(Part 6)
Features
- A monolithic cast-frame structure optimized by finite-element analysis ensures rational load distribution and excellent overall rigidity.
- The main hydraulic cylinder adopts a dual-acting piston design, providing high reliability under repeated high-load operation.
- The piston rod features a dual-layer nickel-chromium plating (0.1mm thickness), offering superior corrosion resistance and wear durability.
- The piston and rod are manufactured as a single forged component, providing exceptional impact resistance and extended service life.
- A high-accuracy column load cell provides excellent strength, stability, interchangeability, and repeatability, with a generous overload range and outstanding linearity.
- The protective enclosure is formed from a single curved polycarbonate panel, ensuring full visibility during testing while providing reliable operator protection.
- The system of the tester is driven by our DSP-based DTC-500 controller, featuring full-digital control, multi-channel data acquisition, accurate data processing, and user-friendly operation.
- The hydraulic power unit is equipped with a cartridge-style logic valve from SUN (USA), enabling intelligent pressure regulation and stable hydraulic performance.
