TL;DR
This paper introduces a web-based platform for real-time telemetry of material mechanical properties using a modernized tensile testing machine.
Contribution
The novel contribution is a cost-effective, multi-client web platform for real-time telemetry and control of mechanical property testing.
Findings
The platform achieved stable performance at 15 Hz with up to 15 simultaneous client connections.
Measurement accuracy was within ±1% for both force and extension, meeting ISO 6892–1 standards.
The system offers an affordable and flexible solution for modernizing traditional tensile testing machines.
Abstract
This paper presents a multi-client web platform for telemetry of mechanical property testing, built around an existing tensile testing machine as an approach to its modernization. Extension and force measurements are performed using potentiometers with analog outputs connected to a 24-bit analog-to-digital converter (ADS1256) integrated with a Raspberry Pi 5 microcomputer. The communication module enables data acquisition and timing, the organization of a wireless Wi-Fi network, the operation of web and DNS servers, and full-duplex information exchange via the WebSocket protocol. A specially developed web application with a graphical user interface allows researchers to observe the “force–extension” curve and numerical values in real time on personal digital devices without installing specialized software. The platform supports simultaneous multi-client access, which increases the…
