A remote tone burst pulser for an electromagnetic acoustic transducer utilizes a circuit having a direct current power source which is provided to a main capacitor. A high power, high speed insulated gate bipolar transistor or metal oxide-semiconductor controlled thyristor is operatively ...
The signal from the sample clock 36 is also applied to a sample pulser 42 which generates a sampling pulse on the sample control line 43 during each cycle of the sample clock signal. The sample pulse signal on the sample control line 43 is coupled to the sample input (S input) of each...
In a mud pressure pulse system, the drilling mud pressure in the drill string is modulated by means of a valve and control mechanism, generally termed a pulser or mud pulser. The pulser is usually mounted in a specially adapted drill collar positioned above the drill bit. The generated pressu...
The increasing use of a variety of ultrasonic transducers in on-site industrial non-destructive testing and evaluation applications has increased the need for a more compact high power tone burst pulser coupled with a low noise receiver in a robust, environmentally secure, compact package. Typical ...
