High-resolution extensometer DT

axialfor process controltensile

Overview
ISO Class 1 compliant differential transformer type extensometers for tensile testing of metallic materials. The DT Series meets the accuracy and method requirements of international standards and is designed for precise strain measurement in standardised tensile tests.

Product type
Differential transformer type extensometers designed for tensile testing of metallic materials.

Features

• ISO Class 1 compliance — Conforms to ISO 9513 and JIS B 7741 Class 1 (±3 μm or ±1 % of specified value, whichever is larger). Also conforms to ASTM E83 Class C.
• Strain-rate control compatible — Supports strain-rate control test methods such as ISO 6892-1 (Method A) and JIS B 7741 (Attachment JB), enabling tests under controlled strain rates.

Applications
Intended for standardised tensile testing of metallic materials where high-accuracy strain measurement and compliance with ISO/JIS/ASTM standards are required (materials testing laboratories, quality control, R&D).
