LBTC-190 Rebar Residual Deformation Tester

Description

Product Introduction:

The rebar mechanical splice residual deformation measuring instrument is primarily used to assess the residual deformation of rebar mechanical splice joints. It comprises two high‑precision electronic extensometers with consistent sensitivity, mounted symmetrically to directly measure the average deformation on both sides of the specimen, ensuring accurate measurement results. The device complies with the standard requirements of JGJ 107‑2016, “Technical Code for Mechanical Splicing of Reinforcing Bars.”

Key features:

1. The two extensometers feature adjustable gauge lengths ranging from 80 to 260 mm, with a measurement range of 10 mm.

2. Employs a microcomputer for high-precision measurement and data processing, features a color display with a sleek, user-friendly interface, and is powered by a lithium battery—no external power cord required.

3. The deformation values of the current test can be saved by number and retrieved by number.

4. Built-in high-capacity memory capable of storing 128 test records;

5. An elastic connection (e.g., a spring or an elastic band sleeve) is used between the bilateral extensometers and the reinforcing bars, ensuring convenient specimen clamping and long service life.

Technical Specifications:

1. Gauge length range: 30–270 mm,

2. Range: 10 mm;

3. Display resolution: 0.001 mm

4. Measurement of rebar diameter: φ5–φ40 mm

5. Accuracy Class: Class 1

6. Color screen display:

Average: Indicates the average of the two channels, Deformation 1 and Deformation 2.

Deformation 1: Indicates the deformation measurement value from the first extensometer.

Deformation 2: Indicates the deformation measurement value from the second extensometer.
