SOLUTION: A first lead wire pair 1 to be connected with the first connecting terminal pair is provided. During operation through this first lead wire pair, a signal current flows and this signal current is the scale of a present measured value. Besides, a second lead wire pair 3 to be connected with the second connecting terminal pair is provided and during operation through this second lead wire pair, a feeding current flows. The value of this feeding current is larger than or equal to a minimum signal current and smaller than or equal to a maximum signal current.

摘要： PROBLEM TO BE SOLVED: To easily formulate a plan of an industrial plant and also to test the plant by memorizing a software device model having a complete image of a device including a parameter, the functionality and a sequence program in every device included in the software device model. SOLUTION: A plant contains three devices 10, 12 and 14 which are connected to a central control unit 18 via a bus 16. The devices 10, 12 and 14 memorize the software device models 20, 22 and 24 respectively. The models 20, 22 and 24 include all relative information on the devices 10, 12 and 14, i.e., all parameters, device functionality and the programs and sequence codes included in the devices 10, 12 and 14 and then load them into the unit 18. Thus, it's possible to easily formulate a plan of an industrial plant and to test the plant without actually operating many existing devices.

摘要： PROBLEM TO BE SOLVED: To execute remote control and/or operation of a field device in a run time environment by sending a program code describing the device function from the field device to a controller and then executing the program code in a run time environment. SOLUTION: A JAVA byte code of a memory 202 is generated by a JAVA compiler 204 by means of a JAVA source code of a file 203. An exclusive JAVA processor 205 executes the JAVA byte code via a field device, and the JAVA byte code is sent to a controller 208 via a field bus 206. In this example, the JAVA byte code is schematically shown on a connection line 213 and filed in a memory 202a. As the JAVA byte code is not dependent on a platform, an object related to parameter description can be used in the controller 208 in a JAVA run time environment and also via an adequate work plane.

摘要： PROBLEM TO BE SOLVED: To set the permittivity of an insert while ensuring high chemical resistance and sufficient mechanical strength for the insert by transmitting/ receiving a microwave through a metallic casing and arranging a dielectric insert in the metallic casing. SOLUTION: A microwave generated from a microwave generator is fed through a coaxial path 5 to the side of a casing 1 thence to an exciting element 6. An end element 7 has an inner space of the casing 1 up to a recess for receiving the exciting element 6 on the side opposite to a container and the inner space is filled fully. The end element 7 is provided with a conical part on the side opposite to the container. The inner space of the casing 1 touching the conical part is filled with a substantially tubular insert 8. The insert 8 is made of a dielectric composed of a composite material of fluororesin and ceramic. The permittivity of the composite material can be approximated by linear interpolation.

摘要： PROBLEM TO BE SOLVED: To facilitate the replacement of sensor assemblies, without changing an evaluation assembly and also to perform DC conductive separation of dielectric strength at low cost by initializing a sensor assembly, based on the data stored in a nonvolatile digital memory and sending a data set to the evaluation assembly via a serial interface. SOLUTION: A sensor assembly 10 includes a nonvolatile digital memory 40 to store all the data, which are necessary for the assembly 10 for acquiring the measurement data and for an evaluation assembly 20 for processing the measurement data. Therefore, the assemblies 20 can be replaced with no changes required to them. Furthermore, the data can only be sent to the assembly 20 from the assembly 10 in a single direction via a unidirectional interface 22. As a result, DC conductive separation of dielectric strength is performed easily between both the assemblies 10 and 20.

摘要： PROBLEM TO BE SOLVED: To provide an apparatus for achieving and/or monitoring a specified filled level in a container, capable of achieving a fixed phase difference between a received signal and a transmitting signal regardless of vibration quality, and capable of obtaining a received input signal faithful to a desired measured signal. SOLUTION: This apparatus is provided with a mechanical vibrational structure and a piezoelectric element 2 having at least three regions. The first(I), second(II), and third(III) regions of the piezoelectric element 2 has a transmitting electrode 21, a first receiving electrode, and a second receiving electrode respectively. The two receiving electrodes 22, 23 have the same shape, and are arranged symmetrically to each other and to the transmitting electrode 21. The first and second regions(I, II) has polarization in the opposite direction to that of the third region(III), and a received signal (E) is equal to the difference between a first signal (E1 ) of the first receiving electrode 22 and a second signal (E2 ) of the second receiving electrode 23.

摘要： PROBLEM TO BE SOLVED: To configure a measuring/monitoring apparatus such that the phase and the amplitude of a receiving signal have elapsing characteristics similar to those of a measuring signal by providing two receivers and receiving signal lines, connecting one receiving signal line with a transmitting signal line through an impedance and generating the differential signal between two receiving signals. SOLUTION: Electric receiving signals E1 , E2 of two receivers 24a, 24b are picked up through signal lines 241a, 2415 connected, respectively, with one electrode of the receivers 24a, 24b. The signals E1 , E2 are multiplexed through an operational amplifier 6 and a receiving signal E (E1 +E2 ) is delivered on a receiving signal line 61 along with the amplitudes of the signals E1 , E2 and the phase difference thereof. Phase of the receiving signal E is shifted by a constant value ΔϕR through an amplifier 7 and a phase shifter 8 and fed back to the transmitting signal. An electric impedance Z acts to maximize the amplitude only of the receiving signal E at the resonance frequency of the apparatus and the phase ΔϕR is subjected to abrupt phase variation of just 180 deg.. Consequently, the receiving signal has elapsing characteristics similar to those of actual transmitting signal.
