Abstract
A downhole transducer assembly capable of being safely operated at a variety of pressures and depths may include a turbine rotatable by a fluid pressure differential rotationally fixed to a rotor in a generator. To reduce the rotational speed of the turbine and rotor, a pressure regulator may limit a fluid pressure differential by controlling the volumetric flow. One or more nozzles may be configured to automatically regulate a nozzle diameter, and therefore the pressure drop across the nozzle. A surge protector may be connected to the generator.
