RTSS-Videoextensometer

Product catalog summary

Overview: The document outlines the application and specifications of a Real Time Strain Sensor (RTSS) system used for tensile and compressive tests, focusing on measuring material properties and strain behavior. It is suitable for dynamic and high-speed tests, vibration analysis, and determining Young's modulus.

Applications: The RTSS system is designed for tensile tests, dynamic strain measurement, and cyclical/periodical tests. It is particularly useful in applications involving hydropulsers and resonance pulsators.

System Features:

Contactless, camera-based optical measurement system.
Measures longitudinal and transverse strain with a rate of up to 1000 Hz.
Strain data can be transferred via analogue signal or digital interface.
Flexible field of view ranging from a few millimeters to several meters.
Strain measurement range from 0.0001% (1µm/m) to over 1000%.
Suitable for all materials and testing machines without influencing the specimen.
Optional image recording and expandable to digital image correlation (DIC).

Technical Specifications:

Distance Resolution: 2µm @ 100mm FOW for HS Version, 1µm @ 100mm FOW for Standard Version.
Measurement Rate: 1000 Hz for HS Version, 70 Hz for Standard Version.
Analogue Output: +/- 10V; 16 bit.
Strain Range: 0.004% - 500% for HS Version, 0.002% - 500% for Standard Version.
Camera Resolution: 2.0 MPixel for HS Version, 2.8 MPixel for Standard Version.
Precision Class: ISO9513 class 1, with camera resolutions for accuracy class up to 0.2 available.

Product Variants:

RTSS: For quasi-static tensile tests with high accuracy (20 µm/m).
RTSS_HS: For dynamic applications with up to 1KHz measurement rate.
Multi-Camera-System: Allows simultaneous measurement of different specimen sides.

Limess Messtechnik & Software GmbH +49 2151 365 28 00 • www.limess.com • [email protected] RTSS (Real Time Strain Sensor) is a optical measurement system based on a digital camera and real time image processing. It measures the longitudinal and transverse strain between two applied lines with a rate of up to 1000 Hz. The strain data is transferred e.g. via an analogue signal or digital interface to the tensile test machines for further processing or controlling. Tensile Test: Determination of Young's modulus Dynamic strain measurement between two indicated lines or markers. Application: Hydropulser • Area of application: Tensile and compressive tests, measurement of material properties, true strain controlled tensile tests, investigation of strain behavior on dynamic tensile tests, cyclical/periodical tests, and dynamic high speed tests, vibration analysis, Young's modulus, resonance pulsators • Flexibel field of view from few mm to some m LIMESS - we measure to the limit
