Product Details

The dual column test stands offer a wide range of materials testing possibilities, with large testing areas and high stiffness frames. The dual column test stands are designed to measure medium or high force ranges on large materials where high precision is required. The dual column test stands come in bench mounted.

The powerful LD Series testing machines from Lloyd Instruments combine high performance, ease of use and superior flexibility. These universal materials testing machines are ideal for testing applications up to 100 kN (22480 lbf) and are designed for both routine quality control testing, automated testing and for performing complex multi-stage testing.

All LD Series testing machines feature an extra-large working area of 452 mm (17.8 in) and crosshead travel up to 1070 mm (42 in) extendable to 1669 mm (65.7 in).

The high stiffness frame incorporates a crosshead guidance system to prevent side loading of the test sample.

Interchangeable pancake load cells ensure high accuracy and optimize the test machines for tension, compression and cycling through to zero force measurements.

An advanced electrical design couples an AC drive with preloaded ball screws for better displacement accuracy.

The flexible NexygenPlus software interacts with Excel and Word, offering you the possibility of automatically transferring your test results directly into your own corporate templates.

A tablet option is available for the LD Series. When combining the LD Series tester with the tablet, the machine turns into a stand-alone test machine that loads all test data directly into the tablet eliminating the need for a computer. With an intuitive interface and quick-test functionalities, setting up a test, selecting test runs and exporting results takes only a few keystrokes. Test results can be exported into both pdf and .csv files.

Extensometers

General purposes Contacting Extensometers are designed for accurate strain and extension measurement of wide range of materials such as semi-rigid plastics, rubbers, wire, cable, textiles and many more, up to a maximum sample thickness of 25mm. These contacting extensometers are also available for Long Travel Extensometers ideal for use when testing high-elongation materials.

The Non-Contacting Video Extensometer is suitable for both the measurement of materials constants as well as long travel applications.

 

Pogo Test Frame

Lloyd Instruments offer POGO systems to provide large working area. The test frames are fitted below the machine base to allow testing of very large samples with the added benefit of optional elevated and ow temperature testing capacity. POGO test frames are available for all single and dual column bench-mounted test machines.

 

Safety Shield

Splinter shields for use with materials testing machines are available to protect the user when testing brittle samples which are liable to fragment. The shields help prevent sample splinters from leaving the test area when performing a test.

Shields for dual column test stands are fully hinged and can be easily opened, allowing full access to the test area from the front or back of the machine. The machine automatically detects whether the doors are open or closed, ensuring the shield is always securely closed before it will perform.

The safety shield can be ordered from factory or locally fabricated.

 

Thermal Cabinets and Furnaces

There are two models of high precision heating and cooling thermal cabinets; the TC540 heating cabinets (40°C to 300°C) and the TC550 heating and cooling thermal cabinets (-70°C to 300°C) used with liquid nitrogen (Customer to provide) for cooling.

For high temperature test applications, we offer the TCF950, a high temperature vertical split furnace with a temperature range from 50°C to 950°C.
