PicoSens single channel signal conditioner

Single channel, handheld signal conditioner for field activities.

The PicoSens 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 PicoSens 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 PicoSens is equipped with a large visible LCD display and can be battery operated. It comes with a standard ±5 V output and a RS-232 communication port for real-time data acquisition. The PicoSens can be controlled directly using the front-panel keypad or remotely using the standard RS-232 interface.

A rugged casing with a removable rubber boot provides good mechanical protection against intensive handling in tough environments.

The PicoSens is compatible with all Opsens Solutions WLPI sensors hence providing a multi-purpose tool for measuring various parameters.

With a 20 Hz sampling rate, a ±0.003 % full scale resolution and a ±0.01 % full scale precision the PicoSens delivers the performances needed for a wide range of critical measurement applications.
