The invention discloses a module resistance sensor which comprises a shell, a first beam, a top cover and a second beam. The shell is hollow, the portion, close to the bottom end, in the shell is provided with the first beam, and the top cover is arranged at the top end of the shell; space between the shell and the top cover is filled with cooling oil, a thermocouple wire is inserted in the oil, a circular hole is formed in the top end of the first beam, and the bottom end of the second beam is installed in the circular hole; the top cover is provided with an inner pipe, the inner pipe is hollow, the top end of the inner pipe is opened, the bottom end of the inner pipe is sealed, and the sealed end is embedded in the top end of the second beam; a water inlet pipe is inserted into the opened portion of the top end of the hollow pipe inside the top cover; space between the hollow pipe inside the top cover and the water inlet pipe serves as water outlet space and a water outlet pipe is communicated with the hollow pipe wall inside the top cover; an elastic sensor is installed on a second beam body; the thermocouple wire is connected with the elastic sensor; the first beam is made of chromate-nickel-titanium alloy and the second beam is made of aviation aluminum.
Description
technical field [0001] The invention relates to a heat flow sensor, in particular to a mold resistance sensor. Background technique [0002] At present, temperature sensors are often used to measure temperature. The current sensor sensing form is relatively simple, and the most commonly used is a thermal resistance heat flow sensor. The method is to derive the heat flow from the relationship between the temperature difference of the thermocouple and the volume of the fluid. This method has poor precision, and the structure of the equipment is complicated and the cost is high. Contents of the invention [0003] Aiming at the defects of the prior art, the present invention proposes a modulo-resistive sensor. The technical scheme provided by the invention is as follows. [0004] A modulo-resistive sensor, comprising: [0005] A shell, the shell is hollow inside; a first beam is installed near the bottom of the shell, and a top cover is installed on the top of the shell; th...
