摘要： A sensor system includes a plurality of strain gauges (12) and a passive compensation circuit (30). The plurality of strain gauges are configured to provide an output voltage indicative of a sensed pressure using an input voltage. The passive compensation circuit that includes a span resistor (R S1 ), first and second compensation resistors (R C1 , R C2 ), and a zero offset resistor (R TZ1 ). The span resistor is connected between an input voltage and the pressure sensor and is configured to control a range of an output voltage for a pressure range of the pressure sensor. The first and second compensation resistors are operatively connected in parallel with the pressure sensor and are configured to control current provided to the pressure sensor. The zero offset resistor is operatively connected between the first and second compensation resistors and the pressure sensor and is configured to control a base value of the output voltage for zero pressure.

摘要： Disclosed is a measuring device (100) for measuring a physical quantity. The physical quantity could be a pressure and/or a force. The measuring device comprises a circular sensing structure (102) comprising a membrane section (102A) which is deflected by force variations acting on the circular sensing structure (102). A first and second strain gauge are attached to the membrane section. The first strain gauge is configured to measure radial strain in a first surface area of the membrane section. The second strain gauge is configured to measure tangential strain in a second surface area of the membrane section. An increase in force acting on the sensing structure results in shrinking of the first surface area measured by the first strain gauge and stretching of the second surface area measured by the second strain gauge.

摘要： A monitoring system including a reading device electrically connected to a probe via a wired interface. The probe has a physiological sensor/transducer configured as a Wheatstone resistive bridge balancing circuit. Integrated within the housing of the probe to prohibit separation during use by a user is a memory device arranged in parallel with the sensor. Communication between the reading device and the probe occurs via a wired interface utilizing a same number of electrical wires between the reading device and the Wheatstone as would be required without the memory device. Control circuitry selects between one of two modes for accessing either data detected by the sensor or the memory device.

The body (10, 60) has an internal space and an introduction passage (110). The internal space is in communication with an outside of the body through the introduction passage (110). The sensing element (40) is disposed in the internal space of the body (10, 60) and capable of detecting pressure of air in the internal space. The projection part (63) is disposed in the internal space of the body (10, 60) or the introduction passage (110) of the body (10, 60), and inhibits liquid from entering the internal space.

摘要： A system and method for pressure measurement may include the ability to readily produce a pressure measurement system. In one general aspect, pressure measurement may include a signal-converting circuit that includes a coupler, a signal biaser, and a signal span adjuster. The coupler is operable to receive a pressure-representative signal, and the signal biaser includes a thermally-insensitive voltage divider that facilitates biasing the pressure-representative signal. The signal span adjuster is coupled to the coupler and the signal biaser and includes a thermally-insensitive voltage divider that facilitates adjusting the span of the pressure-representative signal.
