Background technology
Heat-treatment furnace is the general designation for the industrial furnace that metal works are carried out with various metal heat treatmets.Temperature typically relatively heats
Stove is low.Heat-treatment furnace can use the type of furnace of various heating furnaces, but require more strictly to control furnace temperature and furnace atmosphere etc..Atmosphere
One of installation requirement of sensor is：Measurement point can will correctly reflect heat treatment furnace atmosphere and temperature, and penetration enhancer enters beyond this point
Mouthful or stove in return air dead angle, or the position easily to collide when workpiece is come out of the stove.In the prior art atmosphere sensor typically by
Connector is directly fixed on the inwall of heat-treatment furnace, and necessary encapsulation process is carried out between connector and atmosphere sensor, when
Need regulation atmosphere detection depth then to dismantle connector and re-start installation, cause between connector and atmosphere sensor
Sealing property reduces, and dismounts inconvenience, wastes time and energy.
The content of the invention
