Product Details

The TR220 Transceiver Probe provides the ability to make two-component velocity measurements in difficult to access situations. This unit may be combined with a TR120 to enable three-component measurements. The probe's 25 mm outer diameter, and fully sealed stainless steel construction make this the most compact and versatile LDV probe available. The TR220 operates in the backscatter mode, with receiving optics built in. The probe is equipped with a 110 mm focal length lens, with an optional 144 mm focal length lens available. The lens is user-replaceable and requires no adjustment or alignment. Please refer to the TSI Fiberoptic Probes Brochure for full details.
