Fiber optic Signal conditioner WellSens Gen II Robust & high reliability Multi-channel signal conditioner for harsh environment Description The WellSens Gen II is the next generation of surface controllers. The WellSens Gen II is a robust and reliable multi-channel signal conditioner. It is compatible with the harsh environment interfero- metric fiber optic pressure and temperature sensor, the OPP-W. The WellSens Gen II can operate in a wide range of ambient temperatures from-20°C to +60 °C. The wide operating temperature and low power con- sumption, make it ideal for remote applications oper- ating on solar panels or generators. The modular DIN rail design allows for seamless expansion with growing requirements. The high precision, small foot print, fast sampling rates and ease of use make it the solution of choice for oil field or industrial process applications. At the core of the WellSens is the White Light Polarization Interferometry (WLPI) proprietary technology†. This technology provides a means for making accurate and absolute measurements of the path length difference, which varies as a function of the parameters of interest (pressure or temperature), of any type of interferometric fiber optic sensors. † US patent 7,259,862. Patents pending in other countries. The WellSens Gen II is capable of a variety of interface and communications protocols which provides easy integration to DCS systems via RS-232, RS485, TCP/IP on ModBus or SCPI. It is also offered with an optional LCD display, internal data storage, and can be used independently for direct automation control with programmable alarms, relay logic, and standard ana- log voltage and currents I/O. The WellSens Gen II is a complete data acquisition and processing solution for any application monitoring temperature, pressure, strain, or displacement Use with WLPI fiber optic pressure, temperature, strain & displacement sensors • High Linearity, precision, with fast sample rates. • Expandable up to 128 Channels. • Modular DIN rail design. • Flexible -Supports current & future WPLI products (P/T, Displacement, and Strain sensors). • Wide operating temperature range. • Low Power - <12W for 2 channel (no display).
