Auto Control Retrofit with MOE and Poisson's for Dual Frames

Gilson AC-209 Automatic Controller Retrofit with MOE & Poisson's for Dual Frames for Concrete Compression Machine

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

Gilson’s Automatic Controller Retrofit transforms manual compression machines—whether from Gilson or other manufacturers—into fully automatic systems, significantly improving accuracy, ease of use, and compliance with industry standards. This retrofit is designed to meet the needs of labs conducting tests on concrete cylinders, beams, cubes, cores, and other sample types. By automating critical functions such as specimen contact, pre-loading, rate of load application, break detection, and data acquisition, the system ensures reliable, repeatable, and fully documented results that adhere to ASTM and AASHTO test methods.

Key Benefits of the Automatic Controller Retrofit

• Enhanced Accuracy: Eliminate variations in load rates and testing applications, ensuring consistent, precise results every time.
• Improved Efficiency: Quickly upgrade your existing manual machine to a fully automatic system with minimal downtime.
• Streamlined Installation: Each unit is prewired and preassembled. Simply remove the existing hydraulics and display interface, attach the Automatic Controller Retrofit, connect the new hydraulic hose and limit switch, and calibrate onsite.
• Versatile Applications: Capable of upgrading both single-frame and dual-frame compression machines. Options include configurations for ASTM C469 modulus of elasticity (MOE) testing and Poisson’s ratio analysis.
• Standards Compliance: Meets ASTM C39/39M, ASTM C78/78M, ASTM C109/109M, AASHTO T22, AASHTO T177, AASHTO T97, BS 1610, BS 1881, and more.

Custom Configurations

The Automatic Controller Retrofit is available in various models to suit your specific needs:

• AC-201, AC-203, AC-205: Upgrade manual machines to fully automatic operation. The AC-205 includes an A/B switch for dual-frame machines. All models are compatible with 110V, 60Hz or 220V, 60Hz power sources.
• AC-207 and AC-209: Designed for advanced testing capabilities, including MOE and Poisson’s ratio analysis. The AC-209 also includes an A/B switch for dual-frame machines. Extensometer testing fixtures for these tests must be purchased separately.

Ordering Information

When placing an order, provide the concrete frame capacity and piston diameter of the manual compression machine. This ensures the correct sizing of the pressure transducer and allows for accurate initial factory calibration. Dual-frame machines require additional components, such as an A/B switch, which can be included with your retrofit.

Features at a Glance
