Hydraulic Universal Testing - UTM

Hydraulic Universal Testing Machine

Hydraulic Universal Testing machine is designed for the steel industry. The UTM600-2000 kN offers a unique solution for generating, filing, and displaying quality data. It is built around a specially designed testing machine, and it offers the user a fast and effective way of generating and presenting a quality report for steel and other materials. Additionally, it offers a data filing and retrieving system giving the user instant access to reports on any previously tested sample. Much more than just the test results can be included in the quality report. The TRAM QA software offers the user a simple way to incorporate all relevant quality parameters in a system of tables that can be set up for almost any application. It is ideally suited to quality assurance and process control as well as research and development. It is capable of performing a wide range of complex testing procedures and can be set up for relevant international or national standards e.g. EN 10002-1 or ISO 6892.

General specifications

The special machine design provides optimum stiffness resulting in accurate deformation measurements. An optional extensometer is often used. Testing is controlled from the computer after keying in sample identification. During the testing the load-deformation curve is simultaneously generated on the monitor. The machine is floor mounted.

The loading frame consists of a central cross head and a lower table. The central cross head is adjustable for clearance by means of a geared motor. Compression test is carried out between the central cross head and the lower table whereas tension test is carried out between the centre and upper cross heads. The unit has 6 pillars for better stability. A loadcell senses the force and the movement of the lower table (piston stroke) is measured by an encoder. Hydraulic grips for tension testing of round or flat samples are incorporated in the construction.

Standards

EN 10002	Tensile testing of metallic materials - Method of test at ambient temperature
EN 6892	Metallic materials - Tensile testing - Part 1: Method of test at room temperature
ISO 6892	Metallic materials - Tensile testing - Part 1: Method of test at room temperature

A PC with Tram-QA software makes the machine a powerful "automatic" system for generating, filing and displaying quality data for various productions. Simple to use software will enable the operator to grow familiar with the test machine after a very short time, even if he has no experience at all in operating a computer. The software is supplied in national languages as required.

Comprehensive electronic protection prevents the machine from overloading damage or driving out of limits. A simple calibration procedure is included in the software.
