CoreSens - The New Generation of Signal Conditioner

Designed for the most demanding applications requiring synchronised high speed measurement.

Precise and tailored to your needs, the CoreSens new generation of signal conditioner developed by Opsens Solutions offers high-speed measurements with deterministic synchronization over a large number of measurement channels. With its EtherCAT® interface, multiple CoreSens units can be grouped in single measurement system offering up to 1,300 measurement channels.

The CoreSens unit is built around dual-channel fiber optic measurement modules which are mounted in a rackmount chassis. The WLX-2(S) modules are used with Opsens Solutions WLPI-based technology fiber optic sensors for measuring temperature, pressure, strain or displacement. The GSX-2 modules are used with Opsens Solutions SCBG-based technology fiber optic temperature sensors (OTG sensors). Both type of modules can be mixed in a single chassis and each module has two fiber optic measurement channels each running at sampling rate up to 1,000 Hz and comes with two analog outputs.

Versatile,  Modular and Scalable

The CoreSens unit is the latest generation of Opsens Solutions’ signal conditioners equipped with state-of-the-art technologies. It is a scalable and modular unit with dual-channel measurement modules that can be added as function of your needs.

Highly versatile, the CoreSens supports a broad range of fiber optic sensors and offers measurement sampling rate up to 1,000 Hz. The integrated EtherCAT® fieldbus and interface ensures a true deterministic synchronisation of the multi-channel measurements.

The CoreSens support two different dual-channel modules:

  • WLX-2(S) for White Light Polarization Interferometry (WLPI) technology (Patent # US7,259,862) which provides accurate and reliable measurements of physical parameters such as temperature, strain, pressure and displacement
  • GSX-2 for SemiConductor BanGap (SCBG) technology for measuring fast temperature variations.

Tailored to your needs

The CoreSens is available in multi-module rackmount chassis configuration (up to thirteen WLX-2(S) and/or GSX-2 dual channel measurement modules per chassis) for great modularity. The Master EtherCAT® (CSC-M) or the Bridge EtherCAT® (CSC-B) control interface module can manage up to fifty CoreSens chassis to provide full control over a total of 1,300 measurement channels. A stand-alone unit configuration comprising a single WLX-2(S) or GSX-2 dual channel measurement module is also available.

ServSens: for easy Configuration and Data Acquisition

Opsens Solutions offers a simple and versatile web server application available with all CoreSens configurations. In the chassis configurations and with the CSC-M control unit module, the ServSens application runs in an embedded web server without the need to install any software on customer PC.

The ServSens application provides all the functionalities for system, module and sensor configuration and for real time data acquisition and storage.

Versatile and Open Interfaces

For more flexibility, users can connect the CoreSens system to their own EtherCAT® network (with CSC-B module) or Ethernet network (with CSC-M module).

CoreSens open interface architecture enables users to develop and use their own application interface on EtherCAT® or Ethernet-based communication link with the CoreSens unit. SCPI-like commands for easy programing are supported with both interfaces.

EtherCAT Capability

The EtherCAT® interface and protocol is the ultimate choice for true deterministic synchronisation of high-speed and multi-channel measurements.

Opsens Solutions is proud to offer this state-of-the-art real-time industrial fieldbus on Ethernet technology in all rackmount versions of the CoreSens products.

EtherCAT® is registered trademark and patented technology, licensed by Beckhoff Automation GmbH, Germany.

LogSens: CoreSens Stand-alone

The LogSens software is provided with the CoreSens Stand-alone system for use with the USB interface. The LogSens provides all functionalities for the configuration of the system, the module and the sensors, as well as for the acquisition and storage of data in real time.
