The TSI RV 70 Series Phase Doppler Receiver has optimized optical design for the most reliable phase Doppler measurements over the widest dynamic range. The 72 mm optical aperture allows collection of signals even from a wide range of droplet sizes, with a smaller package size. Optimized optical design, including a non-integer detector spacing, allows phase Doppler systems based on this receiver to reject low-reliability signals from the incorrect scattering component.

With the original patented three-detector arrangement, no aperture masks are ever needed, making this receiver immune to the 'slit effect.' Comes with standard 300mm focal length lens. Lenses are available with focal lengths from 300mm to 1500mm. Please refer to the TSI Fiber Optic Probes Brochure for full details.
