MultiSens multi-channel signal conditioner

Multi-channel, multi-purpose signal conditioner for industrial applications

The MultiSens is a multi-channel, multi-purpose signal conditioner to be used with any of Opsens Solutions’ interferometric fiber optic sensors, i.e. the WLPI fiber optic sensors, for temperature, pressure, strain, and position measurements.

At the heart of the MultiSens is the Opsens Solutions’ White Light Polarization Interferometry (WLPI) technology (patent # 7,259,862) which provides a mean for making accurate and absolute measurements of the path length difference of any type of interferometric fiber optic sensors, whose difference varies according to the measure and of interest.

The MultiSens provides sequential readings over up to 8 measurement channels with a ±0.003% full scale resolution and a ±0.01 % full scale precision. It comes with a standard ±5 Volts output and a RS-232 communication port for real-time data acquisition. The MultiSens can be controlled directly using the

front-panel keypad or remotely using the standard RS-232 interface.

Compatible with all Opsens Solutions WLPI sensors, the MultiSens delivers the performances needed for a wide range of critical measurement applications.
