AI Technical Summary
Technical Problem
Existing nitrogen spring pressure transmitters require connection to the sensor via a hose, which necessitates checking the hose for damage when detecting faults, thus reducing the efficiency of troubleshooting nitrogen springs.
Method used
An embedded nitrogen spring pressure transmitter is designed. By installing the transmitter body inside the piston rod and utilizing structures such as a connecting bracket, mounting bracket, retaining ring, auxiliary ring, and limiting plate, the sensor can be directly installed to directly detect damage to the nitrogen spring.
Benefits of technology
This improves the troubleshooting efficiency of nitrogen springs, avoids secondary inspections, enhances sensor installation stability, and prevents gas leakage.

Abstract
This utility model discloses an embedded nitrogen spring pressure transmitter, belonging to the technical field of pressure transmitters. Its key features include a transmitter body installed inside a piston rod, an external wire on one side of the transmitter body passing through the piston rod, a connecting frame fixed to the bottom of the transmitter body via threads, a mounting bracket rotatably connected to the outer circumference of the connecting frame, a rotating groove on the top of the mounting bracket, and the connecting frame located within the rotating groove. An internal thread is formed on the inner circumference of the piston rod, and this internal thread is threadedly connected to the mounting bracket. This utility model, through the mounting bracket and connecting frame, with the connecting frame fixed to the transmitter body and the connecting frame fixed to the piston rod, can directly detect damage to the nitrogen spring without requiring secondary inspection, thus improving the efficiency of nitrogen spring fault diagnosis.
