7642 High temperature extensometer

17642 High temperature extensometerProduct Introduction:

High-temperature extensometerforDeformation measurement of materials in tensile testing under high temperature environment.These extensometers use high-temperature capacitive sensors and do not require any cooling. They will operate at the maximum temperature limit of most environmental chambers used in material testing.7642Type is suitable for testing composite materials, metals, and high-temperature polymers in tensile, compressive, or cyclic testing. All units can move in both compressed and stretched states. Advanced extensometer accompanyingDT6229controller. The standard output is0-10VDCAnalog signal, factory calibrated through extensometer. 7642It can easily interface with most existing test controllers and can be directly connected to data acquisition systems or chart recorders, or directly connected toPC.7642Can be used for strain control testing, such as low cycle fatigue testing（LCF）.

II7642 High temperature extensometerFeature:

2.1High temperature testing range: from room temperature to700℃.

2.2The standard quick connect kit allows for one handed installation onto the sample.

2.3Durable double bending design enhances strength and performance，It is much stronger than a single bending design, which also allows for cyclic testing at higher frequencies.

2.4The hardened tool steel blade is easy to replace，Each extensometer comes with a spare kit.

2.5Used by the user before leaving the factoryVoltage output (traceable to)NPL）The electronic products have undergone comprehensive calibration.

2.6Standard units comply withASTM B-1Grade accuracy requirements. Includes test certificates. Can be provided upon requestISO 9513 0.5Level Test Certificate
