Automatic Retrofit with MOE and Poisson's Compression

Gilson AC-207 Automatic Controller Retrofit with MOE & Poisson's for Concrete Compression Machine

Upgrade Your Manual Compression Machines with Gilson’s Automatic Controller Retrofit

Gilson’s Automatic Controller Retrofit is a cutting-edge solution for upgrading manual compression machines—both Gilson models and other manufacturers’ systems—into fully-automatic, precision-controlled testing machines. This retrofit brings accuracy, repeatability, and convenience to your concrete testing processes, ensuring compliance with ASTM and AASHTO standards. It is designed to streamline operations for testing concrete cylinders, beams, cubes, cores, and other sample types, while eliminating human error and inconsistencies in load application.

With advanced programming, the Automatic Controller handles specimen contact, pre-loading, rate of load application, break detection, and data acquisition. It eliminates variations in load rates and test execution, delivering reliable results every time. This retrofit ensures strict adherence to ASTM and AASHTO test methods, making it an essential upgrade for laboratories aiming for high efficiency and precision.

Easy Installation for Seamless Integration

The Automatic Controller Retrofit comes prewired and preassembled, simplifying installation. To upgrade your machine, simply remove the existing hydraulics and display interface, attach the Automatic Controller Retrofit, connect the new hydraulic hose and limit switch, and your setup is ready for on-site calibration. This hassle-free process minimizes downtime and allows you to quickly enhance your testing capabilities.

When ordering, you’ll need to provide the existing concrete frame capacity and piston diameter of your manual machine. This information ensures the correct sizing of the pressure transducer and enables us to perform initial factory calibration for optimal accuracy.

Compatibility with Dual-Frame and Specialized Machines

Dual-frame compression machines can also benefit from this advanced system. With the addition of an A/B switch, these machines are seamlessly upgraded to automatic operation. For those performing specialized tests, such as the ASTM C469 modulus of elasticity (MOE) or MOE and Poisson’s ratio testing on 4in or 6in (101mm or 152mm) cylinders, the retrofit includes one or two LVDT inputs. Additional extensometer testing fixtures for MOE and Poisson’s ratio testing are available for purchase.

Factory modifications are also offered to expand the capabilities of your system, ensuring it meets the specific needs of your lab.

Available Models

• AC-201, AC-203, and AC-205: These models upgrade manual compression machines to fully automatic systems. They are compatible with 110V, 60Hz or 220V, 60Hz power supplies. The AC-205 includes an A/B switch for dual-frame machine upgrades.
• AC-207 and AC-209: These models offer expanded capabilities, including MOE and Poisson’s ratio testing. The AC-209 features an A/B switch for compatibility with dual-frame machines.
