An apparatus and method determines ultrasonic measurement parameters of ultrasonic measurements to be performed on a mechanical system, where the ultrasonic measurements are performed using a portable ultrasonic measurement device. The ultrasonic measurement parameters consist of information used in configuring the portable ultrasonic measurement device to make the ultrasonic measurements. The measurement parameters are used to configure an ultrasonic measurement device that uses an ultrasonic sensor to measure ultrasonic characteristics of the mechanical system, where the ultrasonic characteristics are indicative of an operating condition of the mechanical system. The apparatus includes a processor for generating user instruction messages that query a user concerning specific characteristics of the mechanical system on which the ultrasonic measurements are to be performed. The user instruction messages also provide response options from which the user chooses in responding to the instruction messages. The apparatus includes a user communication device that receives the user instruction messages generated by the processor, and communicates the user instruction messages to the user.

A portable digital ultrasonic monitoring system and method for use by an operator in detecting the ultrasonic waves and temperature variations produced by sources such as leaks in pipes, arcing, electrical corona and machinery defects is provided. The digital ultrasonic monitoring system includes a microprocessor based system in a hand held elongate housing that digitally analyzes and stores information received from its sensors. The digital ultrasonic monitoring system provides a referenced decibel output reading of the signal strength of the received ultrasonic signals. In addition, a heterodyned type audio signal that is related to the sensed ultrasonic signals is provided to the operator through a pair of headphones. The portable device has user input keys that allow the operator to select from a variety of different operating modes. A display displays a variety of different readings depending upon the operating mode of the device.

A device detects an emission source of a vibration signal against a background of noise, where the vibration signal is produced by a mechanical system and has one or more frequency components. A sensor senses the vibration signal and produces a sensor signal corresponding to the vibration signal. The sensor has a mechanical frequency selection structure for mechanically resonating at desired frequencies and for mechanically attenuating a frequency component of the vibration signal having a frequency outside the desired frequencies. The mechanical frequency selection structure thus produces a mechanically-tuned sensor signal. Electrical frequency selection filters electrically attenuate a frequency component of the mechanically-tuned sensor signal having a frequency outside the desired frequencies. The electrical frequency selection filters thus produce an electrically-tuned sensor signal. The device has at least one amplifier with gain for producing an amplified signal corresponding to the electrically-tuned sensor signal.
