摘要： A process device for coupling to an industrial process for use in monitoring or controlling the process includes a device housing configured to physically couple to the industrial process. A process variable sensor is configured to measure a process variable and measurement circuitry coupled to the process variable sensor provides an output related to the sensed process variable. A piezoelectric transducer provides an electrical output related to pressure pulsations in the industrial process. Electrical circuitry in the housing includes an input configured to receive the electrical output from the piezoelectric sensor.

摘要： A system and method of monitoring a pressure, temperature, and/or vibration of a hostile environment without requiring the use of active electronics or an oscillator circuit in that environment The system and method interrogate a resonant pressure sensor (41 ) and a resonant or passive temperature sensor (43) connected to a transmission line (.15/17) and located at least 100 feet (30.48 m) away from a network analyzer (23). The system and method use the reflected frequencies from the sensors to determine the pressure, temperature, and/or vibration. If the sensors are networked by the transmission line (15/17) or a network filter, the reflected portion can include the reflected transmission energy. The applied signal and reflected portion travel along the transmission line (15/17), which Is preferably impedance matched to that of the system. If. a multi -conductor cable is used, the effects of the cable's length and temperature are compensated for via a system calibration when in field use.

摘要： A resonant sensor is disclosed which may be arranged to measure the pressure of a fluid. The resonant sensor comprises a diaphragm which may be exposed to a fluid; two supports provided on the diaphragm and a resonator having at least two beams with each beam being suspended between the two supports. The ends of each beam are attached to a corresponding support at more than one point. By attaching each end of the beams to a support at more than one point, the moments and reaction forces to which the support is subjected may be balanced so that distortion of the support and diaphragm due to vibration of the resonator beams is reduced. Consequently, the resonant sensor is able to provide more precise measurements.

摘要： Provided are a pressure measuring method where a pressure is measured with a simple method and with high reproducibility and an intraocular pressure measuring device that is capable of measuring an intraocular pressure only by being made to come in contact with an eyelid and with which a subject himself/herself can perform intraocular pressure measurement. The intraocular pressure measuring device is constituted of a measurer (1), a piezo driver, a terminal base, an information processing device, and a resistor. The measurer (1) is constituted of a vibrator (11) such as a bimorph vibrator, four rubber bases (12), a case (13) vibratable with the vibrator (11) and the rubber bases (12) received in the case, and a contactor (14) coming in contact with an eyelid (16). In intraocular pressure measurement, the contactor (14) is made to come in contact with the eyelid (16). The vibrator (11) is constructed from a bimorph vibrator where an electric current varies according to the inner pressure of an object to be measured in contact with the vibrator with a contact AC voltage applied to the vibrator. A pressure such as an intraocular pressure of the object to be measured is measured by measuring an electric current value flowing in the vibrator.
