Embodiment Construction

[0017] Embodiments of the present disclosure will be more fully described below with reference to the accompanying drawings. Elements identified by the same or similar reference numerals refer to the same or similar elements. However, various embodiments of the present disclosure may be implemented in many different forms, and should not be construed as being limited to the embodiments set forth herein. Instead, it is provided to make the present disclosure thoroughly and complete, and the scope of the present disclosure is completely conveyed to those skilled in the art.

[0018] figure 1 It is an exemplary industrial process measurement or control system 100 according to an embodiment of the present disclosure. System 100 can be used to process materials to convert materials from lower value to more valuable and more useful products such as petroleum, chemicals, paper, food, etc. For example, the refinery performs an industrial process, can process crude oil into gasoline, fuel...

Abstract

A sensor body unit for a pressure sensor, comprising a metal shell and an insulation unit. The metal housing has a first cavity including a first conical inner surface. A portion of the first conical inner surface is concave. The insulating unit includes a first sealing portion within the first cavity and forming a seal with the first conical inner surface.

Description

Technical field [0001] Embodiments of the present disclosure relate to pressure sensors for industrial process measurement and control systems, and more particularly to sensor main units for differential pressure sensors. Background technique [0002] Embodiments of the present disclosure relate to such types of pressure transmitters for industrial process measurement and control systems, and more particularly to pressure sensors for pressure transmitters. [0003] The pressure transmitter is used in the industrial process control system to monitor the pressure of the process fluid in an industrial process control system, which provides output in response to process fluid pressure. The pressure sensor is typically coupled to the process fluid by an isolation device to prevent the pressure sensor from being exposed to the process fluid. The isolation device typically includes one or more isolation diaphragms, each of which is exposed to a process fluid; and one or more isolation f...
