DiTeSt Dual Reading Unit

Downloads

Reliable and high-performance Brillouin Interrogator (BOTDA/BOTDR) for field applications. Measure full strain and temperature profile over fiber optic sensing cables.

The DiTeSt is a unique tool for the evaluation of distributed strain and/or temperature over several tens of kilometers. It is a powerful diagnostic instrument for the identification and localization of potential problems. It allows the monitoring of local strain and temperature at thousands of locations using a single optical fiber and in just one measurement. Its inherent high stability and self-referenced principle of operation allows online or offline long-term monitoring of large structures.

The DiTeSt is a laser-based measurement system using an optical scattering measurement principle within the sensing fiber: Stimulated Brillouin Scattering. It can operate using dedicated fibers and cables as sensing elements. Stimulated Brillouin Scattering is an intrinsic physical property of the fiber material and provides information about the strain and temperature distribution experienced by the sensing fiber.

The DiTeSt-Dual provides four channels with fast and accurate strain and temperature measurements up to 60 km in BOTDA mode and up to 45km with single-end mirror-less measurement.

Multiple fibers can be automatically connected to the instrument through an integrated optical switch. The system includes an industrial PC and internal hard disk storage, allowing great versatility in terms of connections. The integrated software is user-friendly and allows an easy setup of the parameter through the use of self-configuration wizards. The system can operate interactively or in automatic mode, gathering data according to a schedule.

Compatible with SMARTEC DiView software for automatic data management and visualization
