The WellSens Gen II surface controller unit is a robust and reliable multi-channel signal conditioner. It is
compatible with Opsens’ harsh environment interferometric fiber optic pressure and
temperature sensor, the OPP-W. It can operate over a wide temperature range from -40
to +60 °C. Its small foot print, low power consumption, ease of use and its competitive
cost make it the solution of choice for oil fields or industrial process applications.
