Acoustic transducer for rods |
| abstract |
An improved acoustic transducer for use on a cage. An acoustic transducer comprised of transducer elements disposed on an arcuate or arcuate member adapted to fit side-by-side around a saddle. The arcuate member is adapted to supply voltage to the transducer element by a conductor. One embodiment uses a metal arcuate member. Using the embodiment implemented as an acoustic source, the borehole acoustic mode is excited. Some embodiments provide phased array acoustic energy excitation / signal reception. The transducer is covered by a seal in a liquid-free configuration and uses a shield to protect the transducer. [Selection] Figure 3B |
