Description

Technical Field

[0001] The present application relates to the technical field of pressure transmitters, and in particular to an intelligent pressure transmitter. Background Art

[0002] Intelligent pressure transmitter is an automatic measurement and control instrument that integrates pressure sensing, amplification, linearization, temperature compensation, digital processing and communication. It consists of two parts: intelligent sensor and intelligent electronic board. It can be used to measure the pressure of liquid, gas or steam, and convert the pressure signal into a standard signal and output it to the control system. Intelligent pressure transmitter has the characteristics of high precision, strong stability and good anti-interference ability. It is widely used in chemical, electric power, metallurgy, petroleum, water treatment and other industries. It is an important measuring instrument for process control and safety assurance.

[0003] At present, intelligent pressure transmitters are generally divided into multiple structures for assembly. The connector is connected and installed with the pressure transmitter body by welding or fixed and installed by multiple sets of bolts. Although both installation methods have good connection and installation effects, the installation by welding makes it difficult to disassemble and separate the connector and the pressure transmitter body, which makes it inconvenient to inspect and maintain them. The fixed installation by multiple sets of bolts requires that multiple sets of bolts be installed or removed inside the connector and the pressure transmitter body during disassembly and assembly, which makes installation and disassembly more troublesome. Therefore, an intelligent pressure transmitter is proposed. Utility Model Content
