HandySens-W single channel signal conditioner

Compact and robust single-channel signal conditioner for monitoring activities in the field

The HandySens-W is a compact and portable 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 HandySens-W 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 HandySens-W unit is the latest generation of Opsens Solutions’ signal conditioners equipped with state-of-the-art technologies. Highly versatile, it supports a broad range of fiber optic sensors and offers measurement sampling rate up to 250 Hz.

The HandySens-W is equipped with a large and practical 5.0’’ touchscreen display and can be battery operated for remote monitoring projects. The single channel signal conditioner can be controlled directly using the touchscreen display or remotely using Ethernet Interface 10/100 Base-T and/or USB for real-time data acquisition. The unit is equipped with internal storage to provide the required autonomy in remote locations.
