摘要： A method monitors an operational condition of an electric motor, and stores in a memory device general trend, prognostic, diagnostic, and hazardous event information indicative of the motor's operational condition. The method includes the steps of sensing characteristics indicative of the operational condition of the electric motor, such as vibration, temperature, magnetic flux, and the voltages applied to the motor's windings, and generating sensor signals related to the sensed characteristics. Upon the occurrence of a first circumstance, such when measurements of the motor's speed, winding temperature, and voltage, indicate that the motor is operating within its normal load profile, prognostic information is extracted from the sensor signals. The prognostic information provides a profile of the motor's operational condition over time without the influences of fluctuating loads, temperature, and voltage. Upon the occurrence of a second circumstance, such as when the motor's load factor is within a load factor range that is most common for the motor, diagnostic information is extracted from the sensor signals. The diagnostic information indicates the motor's operational condition when it is operating within its most common load zone. Upon occurrence of a third circumstance, such as an indication that the motor is operating abnormally, hazardous event information is extracted from the sensor signals and stored. The hazardous event information indicates the motor's condition at the time that a hazardous event, or fault, occurred. The general trend information is measured and stored at regular intervals to determine short- and long-term operational trends over time.

摘要： An apparatus and method for measuring a breakdown voltage between two electrodes separated by a dielectric. The output of a sensor perceiving the voltage across the two electrodes is transferred to a peak-hold circuit. A spark through the dielectric and across the two electrodes is detected, Restrikes between the electrodes are clamped by precluding further transfers of sensor output to the peak-hold circuit for a predetermined period of time subsequent to the detected occurrence of the spark.

摘要： A low power vibration sensor and wireless transmitter system has one or more sensors that sense parameters of a machine including vibration and produces dynamic signals representing the sensed parameters. The system converts the signals to a digital format, digitally filters the signals, and processes the signals. A processor determines a plurality of levels, which represent the characteristics of the signal such as the peak value of a predetermined set of data points of the digital signal. Together, the levels comprise a PeakVue waveform. The processor determines the peak level value for the PeakVue waveform. Also, a true root-mean-square is calculated as the signal is received at the processor. The peak level and the RMS value are communicated wirelessly by a communication module to a control protocol network such as a daisy chain HART or Fieldbus protocol network. The system power supply and the communication module power supply are separate and allow for low power operation.

摘要： Power saving features are employed in a machine monitor to reduce electrical power consumption and increase the life of an electrical power source (such as a battery) which is used to power the monitor. The monitor includes a microcomputer having a high operating speed and a low operating speed. Power consumption is reduced by placing the microprocessor in a low-power sleep mode when full power capabilities of the microprocessor are not needed. Power consumption is further reduced by operating the microprocessor at the low operating speed when a high operating speed is not needed. The monitor also includes a communications port in electrical communication with the microcomputer for communicating with a peripheral device, and sensors for sensing machine characteristics such as speed, temperature, flux, or vibration. Power switches are employed to remove electrical power from portions of the monitor electronics that are not being used or are not needed, and a DC/DC converter maximizes the amount of electrical power available for use by the monitor electronics. Power consumption is further reduced by the manner in which the monitor processes vibration signals to compute machine speed.
