Description
Technical field
The utility model relates to temperature measuring device technical field, and what be specifically related to is a kind of couple sealing.
Background technique
Thermocouple is temperature measuring element conventional in temperature measuring instrument, and it directly measures temperature, and temperature signal is converted to thermal electromotive force signal, converts the temperature of measured medium by electric meter to.The profile of various thermocouples is often not identical because of needs, but their basic structure is roughly the same, is conventionally made up of major components such as thermode, insulating bush protective tube and terminal boxes, and common and Displaying Meter, record instrumentation and electronic controller support the use.
High-pressure bottle must be drawn thermocouple lead in the time carrying out inner wall temperature measurement from container inner wall, must be provided with lead-in wire fairlead at container wall, is the high pressure sealing that ensures container fairlead place, and installs special thermocouple lead sealing equipment.
