    Abstract: PROBLEM TO BE SOLVED: To provide a method, a device and a system for connecting a process variable transmitting apparatus to a two-line processing device that communicates with a control room. SOLUTION: The device used for the process control system comprises a first pair of electrically connected parts that is so composed as to be connected to a two-line process control loop. The loop includes a two line process variable transmitter. A second pair of electrically connected parts is so composed as to be connected to an input channel, having a multiple input channels. Electrical elements are connected serially in a loop that is used for digital communication with the two line process variable transmitter. COPYRIGHT: (C)2005,JPO&NCIPI

    Abstract: PROBLEM TO BE SOLVED: To reduce a stress generated on an isolation diaphragm by a mounting force of process coupling. SOLUTION: This process transmitter for measuring a process pressure includes a pressure sensor in a sensor housing. The isolation diaphragm for isolating a filled fluid from a process fluid is arranged at a space from a seal of the process fluid. The space reduces deformation of the isolation diaphragm caused by the mounting force. COPYRIGHT: (C)2004,JPO

    Abstract: PROBLEM TO BE SOLVED: To avoid creep of a metalized layer on a flexible diaphragm. SOLUTION: This pressure sensor is provided with a dielectric part moving in a hollow near a condenser electrode fixed to a fitting frame. This diaphragm is supported on the frame and the frame surrounds the hollow. The diaphragm has an outer surface receiving the pressure and an inner surface facing to the hollow. The fixed condenser electrode senses the movement of the dielectric part positioned nearby and generates an electric output expressing the pressure.
