摘要： A digital based two wire proximity transmitter system and a method for calibrating the system, wherein the transmitter includes a customized linearization table uniquely generated during calibration to take into account the unique impedance properties of a particular probe/coaxial cable configuration. During calibration, the probe is positioned adjacent a calibration target. The calibration target is selected to have the same material characteristics as the target to be monitored during actual operation of the transmitter in the field. At a fixed distance between the probe and calibration target, the resonant frequency of the probe/cable system is determined. Thereafter, utilizing this resonant frequency to excite the probe, the voltage response of the probe/cable system is determined as the distance between the probe and the target material is incrementally changed. The voltage output is used to build a table for incremental distances, wherein each distance is characterized by a non-linear output that has been equated to a linear output. This uniquely generated table is subsequently downloaded into the transmitter for reference during monitoring.

The frequency measuring device includes a base member, a sensing line clamp attached to the base member that attaches to the sensing line support bracket, and at least one actuator attached to the base member. The actuator is positioned relative to the sensing line when the sensing line clamp is attached to the sensing line so that the actuator can strike the sensing line. A proximity probe attached to the base member measures vibration of the sensing line and outputs a vibration signal. A processor receives and processes the vibration signal from the proximity probe to determine the natural frequency.

摘要： A combination of an implement employed in a sports game to impact with a body, and a device coupled to the implement which measures the natural frequency and the relative amplitude of vibration of the implement resulting from the impact. The implement can be a game racket, bat, club or the like and the body impacted can be a ball. The lower the value of the natural frequency of vibration of the implement the more flexible the implement is when it impacts the ball, the greater is the amplitude of the vibration of the implement and the rebound of the ball has a lower velocity. One of the embodiments, called a FLEX METER is a frequency measuring device which employs a series of reeds mounted on a base member each reed being adjusted to vibrate at a maximum amplitude when a vibration having a designated frequency is applied to the base member. Each reed is identified with a designated frequency. A light emitting diode associated with each reed emits light when a reed responsive to the vibration of the implement has an amplitude sufficient to make an electrical connection to a closely positioned contact. The devices are all small in weight, size and are portable and convenient to use with the implement.

摘要： A “periodic signal parameter” (PSP) indicates periodic patterns in an autocorrelated vibration waveform and potential faults in a monitored machine. The PSP is calculated based on statistical measures derived from an autocorrelation waveform and characteristics of an associated vibration waveform. The PSP provides an indication of periodicity and a generalization of potential fault, whereas characteristics of the associated waveform indicate severity. A “periodic information plot” (PIP) is derived from a vibration signal processed using two analysis techniques to produce two X-Y graphs of the signal data that share a common X-axis. The PIP is created by correlating the Y-values on the two graphs based on the corresponding X-value. The amplitudes of Y-values in the PIP is derived from the two source graphs by multiplication, taking a ratio, averaging, or keeping the maximum value.
