High Temperature XY Planar Biaxial Extensometer 1200 C or 1600 C)
Model 7651
Jinan Testing Equipment IE Corporation
Model 7651 extensometers measure combined in-plane strains in flat cruciform specimens tested in machines capable of simultaneous X and Y (perpendicular) axial loading and on standard flat samples tested in pure tension. All models are capable of bi-directional displacement in both axes and may be used for strain-controlled fatigue testing under fully reversed load and strain conditions at frequencies up to 10 Hz.All 7651 models mount rigidly on the load frame and incorporate slide mounting to bring the extensometer into contact with the specimen. The gauge length is set automatically before mounting on the test specimen, which allows for hot mounting after thermal equilibrium has been reached.These units are specifically designed to eliminate crosstalk between axes and to provide high accuracy, high resolution measurements. They incorporate capacitive sensors for low operating force and include electronics with programmable filtering and multi-point linearization for improved performance and accuracy. The overall design minimizes, and in many cases virtually eliminates, any influence from common lab environment vibrations.These water-cooled extensometers are equipped with high purity alumina rods with conical rod tips for specimen contact when testing to 1200℃(2200°F). Silicon carbide rods are used for the 1600℃(2900°F) high temperature option.

Miniature Axial Extensometers
Model 3442
Jinan Testing Equipment IE Corporation
Weighing as little as 8 grams, these miniature extensometers are designed to have very low operating force with minimal specimen influence. All use an improved version of Epsilon’s dual flexure design which makes them very rugged for their size. With a module height of 15.2 mm (0.6 inches), they will fit in the limited space between grips that is typical with small test samples. Gauge lengths can be as short as 3 mm or as long as 50 mm. A newly designed gage setting pin and assembly allows the gauge length to be set accurately and repeatably to ASTM and ISO requirements for all gauge lengths. Reengineered quick attach wire forms provide simple and secure specimen attachment. Wire forms for round and flat specimens are included, as well as flat, 3-point, and vee knife edges. The wire forms may be removed to enable mounting using elastic bands or springs. A tethering attachment point provides fall protection and enables counterbalancing of the extensometer’s weight when testing delicate specimens.Model 3442 extensometers are strain gaged devices, making them compatible with any electronics designed for strain gaged transducers. Most often they are connected to a test machine controller and Epsilon will equip the extensometer with a compatible connector wired to plug directly into the controller. For systems lacking the required electronics, Epsilon can provide a variety of solutions for signal conditioning and connection to data acquisition systems, chart recorders, or other equipment.

High Temperature Hot Mountable Furnace Extensometers (1200 Cor 1600 C)
Model 3549
Jinan Testing Equipment IE Corporation
The Model 3549 is a major advancement in the design of externally mounted, furnace extensometers. This new extensometer is designed to meet the stringent requirements of strain controlled testing as prescribed in ISO 6892, while introducing many new innovative features that help improve productivity with static testing applications (tension and compression testing) and long term testing such as low cycle fatigue and creep. The overall design reduces any influence from common lab environment vibrations. This unit also incorporates a new feature that allows the user to precisely set the contact force against the test specimen. This allows for even and repeatable contact force, limiting contact force induced errors. This extensometer mounts on a slide bracket (included) that can attach to the load frame of your test system; optional load frame mounting brackets are available. The gauge length for the 3549 is automatically set prior to mounting on the test specimen, which allows for hot mounting after thermal equilibrium has been reached.

High Elongation Extensometers
Model 3800
Jinan Testing Equipment IE Corporation
The main body of this unique extensometer remains stationary during testing, held in position by the adjustable magnetic base included. Only the very light, small traveling heads move as the sample elongates during a test. These attach to the sample with small spring clips. Each head pulls a cord out from the extensometer as the head moves. These models use high precision, low friction potentiometers, and, as a result, have a wide range of factory selectable outputs. The extensometer is driven by an excitation voltage and has output proportional to the input. They can be provided with high level outputs (approximately 2-8 VDC) or ones that mimic strain gaged devices (2-4 mV/V). When set to mimic strain gaged extensometers, the Model 3800 can be used with virtually any signal conditioning electronics designed for strain gaged sensors. The potentiometers employ a hybrid wire wound around conductive plastic, which provides excellent long term stability. The output from the extensometer is readily interfaced with most existing test controllers, and may be directly input to data acquisition systems and chart recorders. Please let us know at the time of order what type of output and connector you require.

Automatic Extensometer
SIE-560A/560SA
To determine the suitability of a material for an application where it is under load, measuring its elongation is important. Measuring elongation enables determination of the elastic modulus (reversible elongation in the elastic region) by measuring the small initial elongation range, and determination of elongation at specimen failure, by measuring larger irreversible elongation in the plastic region. Shimadzu’s SIE-560A series automatic extensometers accomplish both of these measurements with high accuracy, and provide automated functions that increase testing efficiency and test reproducibility. Ideal for testing a wide variety of materials, including metallic materials, plastics, and composites, the SIE-560A series complies with ISO 527, JIS K 7161, and ASTM D638 standards for plastics tensile testing. In addition, the SIE-560A series supports strain-rate controlled metallic material tensile testing measurements specified in ISO 6892, JIS Z 2241, and ASTM E4

Static Axial Clip-On Extensionmeters
The 2630 series and W-6280 series of extensometers offer speed of attachment and ease of use. The light-weight, rugged cross-brace design eliminates errors caused by physical distortion, while built-in protection ensures that damage is not caused by over-extension. The low operating-force arms of the extensometer reduce the possibility of knife-edge slippage when testing hard or smooth surfaced materials. The 2630 series extensometers can be installed or set in place accurately and consistently, with the gauge length locking device automatically releasing itself after attachment, ensuring speed and reliability of operation. This unique "cone-latch" mechanism also overcomes the problems associated with having to remove pins or clips prior to starting a test, or tests being conducted with the extensometer accidentally locked at gauge length. Because of their larger frame size, the W-6280 series extensometers require two handed operation to attach the instrument to the specimen, so these extensometers still rely on a pin to set the gauge length. All extensometers except the W-6235 allow the ability to measure both positive and negative strain allowing compressive or flexural test measurements.The 2630 series and W-6280 series extensometers include different gauge length and strain range options to suit a wide range of specimen characteristics. All 2630 series and W-6280 series extensometers comply with both the ASTM E 83 and IS0 9513 standards, and gauge lengths are available in metric or U.S. customary units. Calibration certificates are supplied, showing the individual performance of each unit at its factory calibration.Static strain measurement on a wide range of materials and specimens including metals, plastics and composites.
