摘要： A temperature compensating circuit having a third temperature sensor element (RR) for detecting an ambient temperature disposed on the same substrate (10) on which first and second temperature sensor elements (Rx, Ry) are located, and a voltage across the third sensor element, generated by supplying a current thereto, is applied to the first and second sensor elements. Therefore, a voltage applied to first and second sensor elements is automatically changed corresponding to change in ambient temperature, and accordingly a difference in temperature between first and second sensor elements can be precisely detected in a form of voltage signal.

摘要： A capacitive pressure sensor includes first and second substrates, a groove, and first and second electrodes. The first substrate consists of an electrical insulating material. The second substrate consists of the same material as that for the first substrate and has a peripheral portion directly bonded to the first substrate. The groove is formed in a central portion of the surface of one of the first and second substrates. The first and second substrates oppose each other through the groove. The first electrode is coupled to a surface, of the first substrate, which opposes the second substrate so as to be movable together with the first substrate. The second electrode is arranged on a surface, of the second substrate, which opposes the first substrate so as to be parallel to the first electrode. The first and second substrate may consist of quartz glass or sapphire. The first and second substrates are bonded to each other at a temperature lower than the melting point of the substrate material without forming any bonding layer.

摘要： A zero point compensating circuit for a microbridge flow meter including an upstream thermal sensor means, a downstream thermal sensor means and a heater means located between said upstream and downstream thermal sensor is provided which comprises a first switch coupled to said heater for turning on and off the same and a current supply circuit coupled to said upstream and downstream thermal sensors for selectively supplying the same with a first current when said first switch is closed and a second current larger than said first current when said first switch is opened such that said upstream and downstream thermal sensors reach a temperature to which they are heated when said heater is on in no flow condition. Thus, an offset caused by discrepancy in the resistance value and thermal coefficients of resistance (TCR) of the upstream and downstream temperature sensors can be removed by the above circuit, thereby making it possible to achieve a precise measurement of small flow rates of a fluid of interest.

摘要： An electromagnetic flowmeter for obtaining a detection signal by sampling voltages generated from electrodes in contact with a conductive fluid flowing in a magnetic field at a predetermined timing includes an external noise detecting section, a pseudo-noise signal generating section, and a timing signal generating section. The external noise detecting section detects external noise, superposed on the fluid, from the electrodes. The pseudo-noise generating section supplies a pseudo-noise signal for a predetermined period of time if the external noise detecting section determines that no external noise signal is detected. The timing signal generating section generates a timing at which an excitation current for generating the magnetic field is generated, and the sampling timing on the basis of the pseudo-noise signal while the pseudo-noise signal is kept supplied, and causes the external noise detecting section to generate the timing at which the excitation current for generating the magnetic field is generated, and the sampling timing while no pseudo-noise signal is supplied.
