Gilson’s Automatic Controller Retrofit allows Gilson and other manufacturers’ manual compression machines to be upgraded to a fully-automatic operating system. The Automatic Controller is programmed to follow specification requirements for specimen contact, pre-loading, rate of load, break detection, and data acquisition for concrete cylinders, beams, cubes, cores, and other sample types. Variations in load rates and applications are eliminated, ensuring accurate, repeatable, and documented results that strictly conform to ASTM and AASHTO test methods. Each controller retrofit is shipped prewired and preassembled, making it easy to install and integrate with your current manual compression machine.
To install, remove the existing hydraulics and display interface, attach the Automatic Controller Retrofit, and connect the new hydraulic hose and limit switch, the setup is complete and ready for on-site calibration.
The existing concrete frame capacity and piston diameter of the manual machine are required at the time of order to properly size the pressure transducer and perform initial factory calibration.
Dual frame compression machines can also be upgraded to an automatically controlled system by including an A/B switch with the retrofit. Other systems requiring capabilities to perform ASTM C469 modulus of elasticity (MOE), or MOE and Poisson’s ratio testing on 4 or 6in (101 or 152mm) cylinders will include either one or two LVDT inputs. Factory modifications are also available.
AC-201, AC-203, and AC-205 easily upgrade manual compression machines to be fully automatic and operate on either 110V,60Hz or 220V, 60Hz depending on the chosen model. The AC-205 includes an A/B switch to upgrade dual-frame machines.
AC-207 and AC-209 are equipped with the ability to perform MOE and Poisson’s ratio testing. The AC-209 includes an A/B switch to upgrade dual-frame machines. Extensometer testing fixtures for MOE and Poisson’s ratio testing must be purchased separately.
