摘要： A manifold includes a body having generally planar inlet surface. The inlet surface includes a first inlet and a second inlet adapted for coupling to a pressurized process fluid. An outlet surface on the manifold is adapted for coupling to a co-planar transmitter and is at angle relative to the inlet surface. The manifold includes an equalizing valve surface opposite the outlet surface, and a perimeter therebetween. The outlet surface includes first and second outlets in fluid communication with the first and second inlets, respectively.

摘要： An in-line pressure transmitter for sensing an absolute or gage process pressure of a process fluid includes an in-line process coupling. The coupling has a mounting member which includes a substantially flat mounting face and a bore generally aligned with an isolation diaphragm assembly. The member is configured to mount to a flat process coupling.

摘要： An assembly for aligning and supporting an adapter flange for connecting fluid pressures to a pressure sensor body in place on the body and to keep the flange in an unsealed condition to prevent pressurizing the body and flange until installation of permanent fasteners. The support fasteners keep the flange oriented in its normal usable position, but the fasteners retain the flange spaced from the body sufficiently so that the flange will not seal. This will prevent accidentally pressurizing the flange and pressure sensor body until permanent fasteners have been installed. The pressure sensor body is provided with threaded openings for receiving permanent fasteners and the body and flange are shipped with at least one extra set of permanent fasteners different in length from the fasteners used on the flange to permit adding adapters for a process correction. The threaded openings in the body are counter bored an amount selected so that when a different thickness adapted is used for process correction, only the correct length fasteners will be capable of being threaded into the body bores.
摘要翻译： 用于对准和支撑适配器凸缘的组件，用于将流体压力连接到位于本体上的压力传感器主体，并将凸缘保持在非密封状态，以防止加压主体和凸缘，直到安装永久紧固件。 支撑紧固件保持凸缘定位在其正常可使用位置，但是紧固件将凸缘保持足够的距离，使得凸缘不会被密封。 这将防止意外加压法兰和压力传感器主体，直到安装永久性紧固件。 压力传感器主体设置有用于接收永久性紧固件的螺纹开口，并且主体和凸缘运送有至少一组额外的永久性紧固件，其长度与法兰上使用的紧固件的长度不同，以允许加工用于过程校正的适配器。 身体中的螺纹开口被反向钻孔，所选择的量使得当适合的不同厚度用于过程校正时，只有正确长度的紧固件才能够被穿入身体孔中。

摘要： A cable protector comprises a cylindrical reel sleeve having an opening in the side wall, and one open end. A cable that is loosely, helically wound around a central axis to form a coil is inserted into the sleeve with one connector of the cable extending out through the bottom, and the other connector of the cable either retained in the interior of the sleeve or passing out through the opening of the side wall for connection to a second circuit board. The reel sleeve protects the helically wound cable from external damage, and the connector from the center can be coupled to a circuit board in a first transmitter housing, and retained in the protector to prevent damage to the cable during assembly of the housings. A second transmitter housing mounts a shroud that rotatably mounts the reel sleeve holding the cable, so that when the two transmitter housing sections are threaded together, the sleeve containing the wound cable will be guided into the shroud and will be permitted to rotate therein without damaging or twisting the cable as the two housing parts are threaded together or repositioned.

摘要： A pressure transmitter has a pressure sensor coupled to an isolator diaphragm by a fill fluid such as oil. According to the invention, means are provided for measuring the position of the isolator diaphragm and comparing the measured position with an expected position to give an indication of fill fluid leakage. Non-contact arrangements such as capacitive and ultrasonic techniques are disclosed for measuring isolator diaphragm position, as well as contacting arrangements such as switches. The fill fluid loss arrangement can be incorporated into a two-wire transmitter, which transmitter can be made to send a warning signal to a control unit when fill fluid loss is detected.
