摘要： A SAW-based micro-sensor apparatus for simultaneously monitoring acceleration/vibration and temperature utilizing a sensing element configured as a SAW device (e.g., SAW resonator or SAW delay line). The SAW device can be located in different locations on a substrate with respect to a thin piezoelectric diaphragm comprising an inertial mass. The temperature-compensated acceleration/vibration can be measured utilizing a frequency difference between an acceleration sensitive SAW resonator (e.g., SAW-g) and a temperature sensitive SAW resonator (e.g., SAW-T). The temperature can be measured utilizing a frequency shift provided by the SAW-T and a temperature reference SAW resonator (e.g., SAW-R). Similarly, the phase response of different reflectors of the SAW delay line can be utilized to differentially measure the acceleration/vibration and temperature.

摘要： The invention relates to a remotely interrogable SAW (surface acoustic wave) temperature sensor comprising. At least two resonators (T1, saw, T2, saw) have transducers having interdigitated electrodes connected to control buses of design such that they have different characteristic operating frequencies. A first resonator has a first surface acoustic wave propagation direction, parallel to one of the axes of the substrate, and a second resonator has a surface acoustic wave propagation direction making a nonzero angle (β) with the propagation direction of the first resonator. The control buses of the second transducer are inclined at a nonzero angle (γ) to the normal to the interdigitated electrodes of the second transducer so as to compensate for the power flow divergence of the acoustic waves along the second transducer.

摘要： A method of determining the temperature inside a combustion liner without making a direct measurement of the actual temperature. The technique is based on a measurement of the frequency of one of the transverse acoustic modes occurring inside the combustion chamber. The frequency is determined from the transverse geometric dimensions of the combustion chamber and the speed of sound in the gas inside the combustion chamber. The speed of sound in the gas is known from thermodynamics to be a function of gas temperature and gas properties. Thus, from a measurement of the resonant frequency and knowing the combustor dimensions and gas properties, the temperature can be determined with accuracy.

摘要： A detector unit of a thermometer of this invention is comprised of a pair of oscillators which are closely installed each other. We make a latch signal of a counter circuit for specially made crystal resonator whose number of proper vibration changes with temperature, and latch a counter value of a counter circuit for reference crystal resonator by said latch signal. We calculate the temperature by a microcomputer using the latched value from the said reference crystal resonator. The power consumption of an electric circuit of the detector unit is less than 0.6 mW under the condition of the supply voltage at DC 2.5V.

摘要： The interior space of a combustion chamber, boiler, or other such gas-filled chamber exhibits an acoustic response spectrum to acoustic energy excitation which includes plural maxima attributable to acoustic natural-vibration frequencies. The frequencies of these natural vibrations are dependent upon both the interior temperature of the chamber and also upon the normality or molarity of the gaseous contents of the chamber. One of these two variables, i.e., temperatures or else normality or molarity, is measured by conventional devices. The other variable is then measured using a pressure transducer generating an electrical signal indicative of the chamber interior's acoustic response spectrum, the transducer output signal being applied to a discriminator circuit which develops a measurement signal indicative of the value of the variable being measured. In this way, interior temperature can be continuously monitored by acoustic devices with high accuracy.
