LifeSens – Single Channel Signal Conditioner

Signal Conditioner Optimized for Measuring Physiological† Pressure.

The LifeSens is a compact signal conditioner specifically designed for measuring physiological† pressure. When combined with OpSens’ OPP-M fiber optic sensors, the LifeSens delivers outstanding pressure measurements with all the features required for life science applications.

The LifeSens benefits from OpSens’ White Light Polarization Interferometry (WLPI) technology (Patent # 7,259,862), providing the most accurate and reliable absolute Fabry-Perot cavity length measurements.

The LifeSens delivers pressure measurements at a rate of 250 Hz. An internal manometer automatically corrects for atmospheric pressure change. The system accepts the OpSens’ SCPROM connector that stores OPP-M sensor gauge factor. Upon mating the sensor, the gauge factor is seamlessly transmitted to the LifeSens conditioner.

The LifeSens 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 LifeSens 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.
