Torsion Calibrator Accessory – Model 3590-TORSION

This calibrator accessory is designed to be used with Epsilon Model 3590 and 3590VHR calibrators to perform axial-torsional calibrations and verifications.

38 EXTENSOMETER MODELS are available in many thousands of variations. Our focus on helping customers has led to the development of models to cover nearly any test method.

Operation of these, and all of Epsilon’s extensometers, are

VERIFIED TO APPLICABLE STANDARDS SUCH AS ASTM E83 OR ISO 9513

using in-house calibration systems that are calibrated with Epsilon’s laser interferometer system.

WITH OVER 30 YEARS OF SERVICE
to the materials testing community, you know we will be there to stand behind our products when your critical application requires it.

Epsilon’s 3590-TORSION Calibrator Accessory is designed for use with Epsilon models 3590 and 3590VHR Calibrators. It is designed for torsional calibration or verification of extensometers, including Epsilon axial-torsional models 3550, 7650, and 3550HT. The accessory includes a mechanical rotation subassembly and a calibrated and traceable linear displacement head.

Readings must be converted from displacement of the linear measuring head to torsional rotation of the calibration rig: 1.27 mm (0.050”) = 1 degree twist. The digital display reads in millimeters or inches and can be zeroed at the touch of a button.

0.001 mm (50 microinches) resolution of the displacement head.
±0.004 mm/25 mm (±0.00015 in/in) accuracy of the displacement head.
Torsional ±10 degree measuring range.
Includes 25.4mm (1”) diameter posts.
Digital display with selectable length units and a zero button.
The linear displacement head is calibrated and traceable in length units. Customers must convert linear displacements to rotational units.
Foam lined case for storage included.

Standards Labs in most countries have signed a Mutual Recognition Arrangement CIPM MRA. This includes the NPL in the UK, NIST in the USA and many others. This makes them effectively traceable to each other. Services of the NPL are equivalent to those offered by NIST and are recognized by NIST through this agreement of reciprocity.
