Universal 3-zone furnace controller
For creep testing in an extended temperature range, exact temperature control along the specimen throughout the full duration of the test is essential. The temperature controller developed by ZwickRoell and proven for many years, ensures precise, reproducible, and user-independent temperature control of the specimen during every test. The universal 3-zone furnace controller meets all requirements of the current international test standards such as DIN EN ISO 204, DIN EN ISO 6892-2, ASTM E139, ASTM E21.
Specimen temperature measuring device
For temperature measurement directly on the specimen the ZwickRoell creep testing systems are equipped with a specimen temperature measuring device.
For creep tests normally up to three thermocouples are used, which are connected to the specimen. With the connection of the thermocouples it is ensured that the specimen temperature is measured on the correct location throughout the duration of the test.
Load string for tests up to +1,500°C
For creep testing in high temperatures, ZwickRoell offers high-temperature load strings up to +1,500°C.
The load string consists of:
- Pull-rod mounting
- Pull rod
- Specimen adapter
The high-temperature load string transmits the force from the high-temperature specimen adapters in the furnace to the pull-rod mountings outside the furnace. For creep tests in extended temperature ranges the pull-rods and specimen adapters therefore have to hold up to special thermal loads. Metallic high-temperature pull-rods are ideal for use up to +1,200°C and ceramic high-temperature pull-rods up to +1,500°C.
The differentiating advantage of extensometers featuring non-contact measurement is that they can be used right up to break without risk of damage, even with specimens that are critical in this respect. Sensitive specimen remain unaffected and with the laserXtens the need for time-consuming specimen marks is eliminated. Especially in an extended temperature range, non-contact extensometers provide a defining advantage over contact extensometers, since the access to furnace and temperature chambers can be sealed with view windows. Additional features such as another measurement axis for transverse strain and determination of strain distribution are further unique qualities that only a non-contact measuring system can offer.
With the wide selection of non-contact extensometers, our engineers are happy to help you find the right product for your application.
Contact extensometers for creep testing are available for tensile as well as compression and flexure tests. In addition to different accuracy classes and measurement ranges, extensometers for extended temperature ranges are also available. A distinction is made between side- and axial-attaching extensometers, which are suitable for special test types such as crack propagation testing. Depending on the specimen shape, different sensor arms are used. Well designed swivel units allow for easy operation and fast test-readiness.
