Bellows on - line monitoring device

The utility model discloses a bellows on - line monitoring device, include: closing plate, closing plate are installed in the middle of adjacent bellows, can seal bellows, stay tube, stay tube are installed on the platform truck, can fix bellows, the threading pipe, the threading pipe is installed on the stay tube, flexible thermal resistance, the first end of flexible thermal resistance connectswith the first terminal filament of threading pipe, and the second end of flexible thermal resistance can pass the threading pipe and insert to the inside of bellows. The utility model discloses owingto installed the closing plate that sealed bellows were used the adjacent bellows in the middle of, the inaccurate problem of monitoring point temperature display that the wind of having avoided effectively going here and there each other between the bellows of platform truck lower part leads to. In addition, replace the thermocouple with flexible thermal resistance, flexible thermal resistance has ...
