Optical Shear (OS) Series | OSU-1001-H2U (Half Width 2 Rack Units)
The OSU-1001-H2U AC/DC Differential Optical Sensor Unit is an integrated fiber optic and electronic system that provides the ability to measure mean and fluctuating quantities of interest using a differential optical sensor, e.g., wall shear stress or pressure. The OSU provides a stable light source and fiber optics to transmit light to and from the sensor head as well as optoelectronics to convert the light reflected from the sensor head to a single analog voltage signal for output to a data acquisition system.
Two integrated rechargeable lithium ion batteries minimize noise due to EMI and provide up to 20 hours of continuous operation. The control unit makes use of transimpedance amplifiers and an instrumentation amplifier to enable measurement of both mean and dynamic components.
This control unit pairs with the following sensor.
