进口双金属温度计Product description:

The bimetallic thermometer includes a thermometer housing, the left end of the inner wall of the thermometer housing is fixedly connected with a glass plate, the inner part of the glass plate is provided with a pointer, the center of the lower surface of the thermometer housing is fixedly connected with a threaded rod I, the lower surface of the threaded rod I is fixedly connected with a heat conducting rod, and the lower part of the bimetallic thermometer is provided with a connecting device, which includes a threaded tube, The lower end of the outer side of the threaded tube is connected with a casing by thread. A connecting rod is fixedly connected at the circumferential edge of the lower surface of the casing. The bottom support device includes a bottom plate, which solves the problem that when the existing bimetallic thermometer is measuring the temperature of a water body, a person needs to hold the thermometer to insert the heat transfer rod of the thermometer into the water body, and needs to maintain a certain insertion depth. The hand-held thermometer is easy to fatigue and shake, which leads to large measurement errors.

进口双金属温度计characteristic:

The bimetal thermometer combines two metals with different linear expansion coefficients, and one end is fixed. When the temperature changes, the two metals have different thermal expansion, which drives the pointer to deflect to indicate the temperature. This is the bimetal thermometer, as shown in the figure on the previous page. The temperature measurement range is ? 80 500C, which is applicable to the temperature measurement when the accuracy requirement is not high in industry. As a temperature sensing element, bimetallic sheet can also be used for automatic temperature control.

进口双金属温度计Principle:

The bimetal thermometer is equipped with a connection device. When the insertion depth needs to be adjusted, rotate the casing to make the bottom support device and the floating support device rise or fall relative to the bimetal thermometer, so as to change the length of the heat transfer rod under the bottom plate, and then place the entire device on the water surface. At this time, the height of the bottom end of the heat transfer rod in the water body changes, so as to change the measurement depth, The variable can be easily controlled and the accuracy can be improved.
