Part or other parts.
As shown in Figure 1 to Figure 3, filled according to a kind of overtemperature protection of pressure sensor of the utility model embodiment
Put, to prevent pressure sensor 1 from being overheated when measuring the pressure of medium, the overtemperature protection system of pressure sensor includes：Base
2nd, Banjo pipe joint 3 and radiating tube 4.Base 2 includes：Screwed hole 21 and bottom outlet 22.Screwed hole 21 is opened in the top of base 2
Portion, and being connected with screwed hole 21 of can dismantling of pressure sensor 1；Bottom outlet 22 is opened in the bottom of screwed hole 21, and bottom outlet 22
Connected with screwed hole 21.Banjo pipe joint 3 is connected with medium.And the one end of radiating tube 4 connects with the side of bottom outlet 22, and dissipate
The other end of heat pipe 4 connects with Banjo pipe joint 3.Wherein, Banjo pipe joint 3 by the pressure of medium by radiating tube 4 and
Base 2 passes to pressure sensor 1, and radiating tube 4 is to the pressure of medium progress radiating and cooling.
Preferably, base 2 is cylindrical rod iron structure, and base 2 also includes turret head 23, and it is opened in base 2
Bottom, and the effect of six brilliance 23 is when installing pressure sensor 1, and turret head 23 can be blocked with spanner, fixes base
2, in order to install pressure sensor 1；Radiating tube 4 is steel pipe, and the internal diameter of radiating tube 4 is 5 millimeters to 15 millimeters, radiating tube 4
