In order to guarantee the best possible performance for different applications, we use different technologies for our interrogators that are matched to the corresponding sensors. On the one hand, the systems based on gallium arsenide technology (semiconductor band gap) for the temperature sensors of the Opsens OTG series and COMEM TS sensors and, on the other hand, the systems based on white light interferometry (WLPI) for the OTP sensors.
Opsens CoreSens
Versatile and scalable, supports WLPI and SCBG sensors
The readout system offers high-speed measurements with deterministic synchronization across many measuring channels. With its EtherCAT® interface, several CoreSens units can be combined to form a measuring system with up to 1,300 measuring channels.
The CoreSens unit consists of two-channel fiber optic measurement modules in a rackmount chassis.
- The WLX-2(S) modules based on WLPI technology (White Light Polarization Interferometry) are used with fiber optic sensors based on WLPI from Opsens Solutions to measure temperature, pressure, strain or displacement.
- The GSX-2 modules based on SemiConductor BanGap (SCBG) technology are used with fiber optic temperature sensors (OTG sensors) with SCBG technology from Opsens Solutions to measure rapid temperature fluctuations.
Both module types can be combined in a single housing. Each module has two fiber optic measuring channels with a sampling rate of up to 1,000 Hz and two analog outputs.
Versatile, modular and scalable
The CoreSens unit is the latest generation of interrogator systems from Opsens Solutions. The device is modular and scalable. Dual-channel measurement modules can be added as required.
