Embodiment Construction

[0021] Objects and functions of the present invention and methods for achieving these objects and functions will be elucidated by referring to the exemplary embodiments. However, the present invention is not limited to the exemplary embodiments disclosed below; it may be implemented in various forms. The essence of the description is merely to assist those skilled in the relevant art to comprehensively understand the specific details of the present invention.

[0022] The present invention is aimed at that the existing plug-in flange type pressure transmitter is easy to be damaged by corrosion when measuring the pressure of highly corrosive medium (such as royal acid). A series of problems such as difficult control of the production process are provided, and a corrosion-resistant remote transmission assembly with a flange type measurement with an inserted cylinder and a remote pressure transmitter including the remote transmission assembly are provided. The remote pressure tr...

Abstract

The present invention provides a remote transmission module used for a remote transmission pressure transmitter. The remote transmission module comprises a remote transmission part and a tantalum mebrane (6), a tetrafluorohydrazine sleeve (2) and a tetrafluorohydrazine cover (4) coating the outer surface of the remote transmission part, and a fluororubber seal ring configured to seal the tantalummebrane (6), the tetrafluorohydrazine sleeve (2) and the tetrafluorohydrazine cover (4). The present invention further provides a remote transmission pressure transmitter having the remote transmission module. Compared to an original a remote transmission pressure transmitter made of tantalum materials. The remote transmission pressure transmitter reduces the production and usage cost and ensure the long-term, stable and safe work of an instrument.

Description

technical field [0001] The invention relates to the technical field of measurement, in particular to a corrosion-resistant flange-type remote transmission assembly with an inserting cylinder and a remote transmission pressure transmitter including the remote transmission assembly. Background technique [0002] A pressure transmitter is a device that converts pressure into pneumatic or electric signals for control and remote transmission. It can convert physical pressure parameters such as gas and liquid sensed by the load cell sensor into standard electrical signals to supply Secondary instruments such as indicating alarms, recorders, and regulators are used for measurement, indication and process adjustment. Pressure transmitter is the most commonly used sensor in industrial practice. It is widely used in various industrial automation environments, involving water conservancy and hydropower, railway transportation, intelligent buildings, production automation, aerospace, mi...
