Abstract: Systems and methods for testing steam traps or other similar devices in a hot water or steam system are described. A tester includes a wand that is handheld that can communicate with a handheld electronic device which in turn can communicate with a central monitor for storing and compiling readings as historical profile data. The wand includes a probe to physically contact the device to acoustically sense the performance of the device. The probe includes a probe tip and a stack of acoustic elements, an electrode, a stack mass, and a head to covert the acoustic signal into an electrical signal. The handheld device includes circuitry to process the information, interact with the user, and transmit information to and from the handheld electronic device and/or the central monitor.

Abstract: A downhole tool having an acoustic transducer for downhole measurements. A backing is in contact with an inner surface of the transducer. A first structure is coupled to a first housing. A second structure is coupled to a second housing. A member includes first, second, and third portions. The first portion is coupled to the first structure. The second portion is coupled to the second structure. At least one of the first and second structures is coupled to the member and has a degree of freedom relative to the member. The third portion extends longitudinally through the backing between the first and second portions such that compressional forces on the first and second housings are transferred through the first and second structures and the backing. A canister contacts an outer surface of the transducer and exerts radial forces on the transducer when exposed to pressures higher than atmospheric pressure.

Abstract: A compact, rugged and portable measurement cell design for the determination of sound speed in fluids at temperatures up to 250° C. and pressures up to 3,000 psi is described. Swept Frequency Acoustic Interferometry measurement for liquid sound speed determinations in liquids up to 250° C. is of both fundamental interest, as in the case of basic equations of state, and applied interest, such as for characterizing geothermal or petroleum down hole environments. Representative sound speeds for water, as a function of temperature and pressure, are in agreement with an internationally accepted standard for the sound speed of water.

Abstract: A method for measuring the deformation of elastomeric materials using acoustic signals involves obtaining a sample, positioning the sample in a sealable chamber, sealing the chamber, and setting a temperature and pressure inside the chamber. A test fluid may be introduced to the chamber. An acoustic signal is used to measure a characteristic of the sample, such as a dimension or a modulus. Repeated measurements may be made overtime to monitor changes in the sample in response to temperature and pressure. The acoustic signal may be generated by an acoustic transducer including a backing component including a fluorine-containing polymer in which metal particles are incorporated. The sample may be a non-metallic material. Conditions inside the chamber may be set to simulate a wellbore environment.

The chamber includes a first chamber being pressurizable to a first pressure and a second chamber pressurizable to a second pressure. The rock sample is positioned within the pressurizable chamber such that a first portion of the sample is exposed to the first pressure and a second portion of the sample is exposed to the second pressure. The second pressure is increased to a threshold pressure, maintained at the threshold pressure for a time period, and then decreased. The acoustic sensors detect one or more acoustic events occurring within the rock sample. In certain embodiments, one or more of the intensity, the spatial location, and the propagating direction for one or more acoustic events are determinable. The system includes the testing device coupled to a recorder.

Abstract: A sensor for detecting stress waves for use in a stress wave analysis system. The stress waves are preferably detected in a narrow frequency range of 35-40 KHz. At this range, stress waves from friction and impact sources typically propagate through machine structures at detectable amplitudes. In order to maximize the signal to noise ratio of stress waves, relative to background noise and vibration, the sensor of the present invention is designed and calibrated with a frequency response and damping features that are specifically tailored for stress wave analysis. The sensor is a multi-functional sensor that can measure a number of logically related parameters for indicting the mechanical condition of a machine. It is often desirable to measure both friction and one or more other parameters appropriate for indication of a machine's health, where all of the measuring capability is contained in one sensor. The multi-functional capability of the present invention significantly reduces the acquisition, installation, and maintenance costs of the condition monitoring instrumentation system.
