LifeSens - Single Channel Signal Conditioner
From OEM/Life Science Solutions
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.
Product Details
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.
