Abstract

The invention relates to a miniature fixed-point temperature dynamic display meter, which mainly consists of an I-shaped frame, an LED (light emitting diode), a steel pin, a capillary, a battery, a copper box and mercury, wherein as shown as figures 1 and 2, the I-shaped frame, the copper box and the capillary form a communicating vessel, the steel pin is pricked on the capillary, a ceramic ring and the mercury are arranged in the copper box of the communicating vessel, an air chamber of the I-shaped frame is filled with compressed gas, a mercury column of the capillary backwards moves after the copper box is heated, and the contact between the mercury and the steel pin is broken, so that the original luminous LED is turned off, and the temperature dynamic change can be sensed according to the on-off state of the LED. The miniature fixed-point temperature dynamic display meter has the advantages that no moving component is used, the miniature structure is adopted, the performance is stable, durability is realized, the manufacturing is simple, the long-sight-distance observation is convenient, and the network display is realized.

Description

Technical field [0001] The invention relates to a miniature fixed-point temperature dynamic display meter, which is small in volume, large in measuring range and fast in heat balance, and is especially suitable for long-distance observation or network display of fixed-point temperature dynamics. Background technique [0002] The common glass rod thermometer is maintenance-free and has good repeatability of measurement results. Although it is widely used, it is fragile, has a long thermal equilibrium time, limited range, difficult reading, and cannot be used for network group measurement, which limits its use in industry, agriculture, and military affairs. , Wider use in life. Contents of the invention [0003] In order to overcome the existing deficiencies, a miniature fixed-point temperature dynamic display table is provided to people, which has 1. microstructure, simple manufacture, 2. network display, 3. strong overload capacity, 4. good repeatability of fixed-point tem...
