One end of pull bar is repaid, the first compensation linkage center is fixed on movement, and the first compensation linkage other end connects the second compensation linkage
One end, the other end of the second compensation linkage is connected with movement, and movement top is provided with pointer.
Further, described bourdon tube uses multi-turn bourdon tube.
Further, it is provided with O-ring seal between described relief valve and watchcase.
Further, the length of described capillary is 1-4 rice, and the material of capillary can be that copper or aluminum snakeskin is soft
Pipe.
Further, the material of described thermometer bulb can select red copper or stainless steel it is therein any one.
Further, the range ability of described dial is：50-650℃.
The beneficial effects of the utility model：
1st, C-spring pipe of the prior art is different from, the utility model uses multi-turn bourdon tube, is effectively improved temperature
Degree meter antidetonation and stability, while bigger pressure can be also born, improve the service life of thermometer.
2nd, the utility model uses compensation linkage, when surface temperature is higher than 100 DEG C, plays certain compensating action, no
Influenceed by environment temperature, effectively increase the measurement accuracy of temperature.
