Abstract

This utility model relates to the field of pressure transmitter technology, and in particular to a high-temperature resistant pressure transmitter, including a support plate, an outer protective assembly on the top of the support plate, and a heat dissipation assembly on the top of the outer protective assembly. Through the coordinated use of a mounting box, an integrated telescopic rod, a stop plate, a buffer spring, and a protective pad, the mounting box protects the transmitter's exterior. After adjusting the integrated telescopic rod, the pressure gauge is fixed using the stop plate. The buffer spring between the side plate and the stop plate provides a shock-absorbing effect during fixing. Furthermore, the outer surface of the stop plate is equipped with a protective pad to prevent instability during fixing. The mounting box and the support plate use a snap-fit ​​design for easy installation and disassembly, thereby improving work efficiency. A temperature detector facilitates internal temperature monitoring, allowing operators to easily understand the values. Starting the fan provides heat dissipation for the internal components and the transmitter.
