摘要： A differential pressure transmitter is an improvement over the drawbacks of conventional apparatuses and provides a differential pressure transmitter which compensates for adverse effects of a static pressure by using a static pressure detecting piezoresistive gauge. The transmitter includes a highly sensitive static pressure sensor with high outputs, and a composite sensor with small crosstalk between the static pressure sensor and a differential pressure sensor. The differential pressure transmitter is constructed of semiconductor sensor substrate and a fixed mount on which the sensor substrate is securely mounted; whereby the differential pressure of a fluid is detected by utilizing the difference in Young's modulus between the sensor substrate and the mount. The sensor substrate is processed on one side or on both sides to make a part of the sensor substrate thinner than the surrounding parts and thereby cause a peak stress due to a static pressure load to occur at the thin part, and a change in resistance of a semiconductor piezoresistive gauge formed at that thin portion is detected.

摘要： In an integrated multisensor used in a differential and static pressure transmitter, a pair of static pressure gages are formed on a static pressure detecting diaphragm and another pair of static pressure gages are formed at positions on a fixed portion which are near to the center of a differential pressure detecting diaphragm. The second term generated by a differential pressure appearing in a static pressure sensor is a function of a distance. Therefore, equal influence is exerted on each static pressure gage. Accordingly, by constructing a static pressure sensor so as to form a bridge circuit, a static pressure value free of the influence of a differential pressure can be detected, thereby making it possible to determine an accurate differential and static pressure.

摘要： A measuring and controlling system is provided which has a control function as well as a measurement function to perform the measurement and control of fluid amounts such as the flow rate, pressure, liquid level, weight and so on by itself in the same field. A pressure receiving unit is directly mounted on a pipe or a container, in which a fluid under measurement exists, in order to detect the temperature, differential pressure and static pressure of the fluid under measurement independently of each other. Means for storing the characteristic of fluids under measurement is provided such that the mass flow rate, weight and liquid level can be calculated. By providing the transmitter with the measurement and control functions, the measurement and control of fluid amounts such as flow rate, pressure, liquid level, weight and so on can be performed in a closed form, thereby making it possible to simplify a correction procedure for the static pressure and temperature, improve the responsibility, and enhance the control performance of the whole plant. Also, a measuring and controlling system can be realized which reduces a wiring amount for connecting with an upper level control unit.
