Abstract
The utility model provides a high-precision pressure gauge with a temperature compensation function. The high-precision pressure gauge comprises a gauge housing, wherein a machine core, a pressure gauge pointer and a spring tube are arranged in the gauge housing; a machine core shaft is arranged on the machine core; the spring tube is connected with the machine core shaft; a fixed box is further fixedly arranged on the machine core shaft; an elastic compensation piece is arranged in the fixed box; one end of the elastic compensation piece is fixedly connected with the fixed box; and the other end of the elastic compensation piece is connected with the pressure gauge pointer. When the pressure gauge is used to measure pressure, the machine core shaft is driven by the spring tube, the fixed box is driven by the machine core shaft, the elastic compensation piece is driven by the fixed box, the pressure gauge pointer is driven by the elastic compensation piece to be aligned with a corresponding scale on a dial, and then a pressure measurement value can be read out. When the ambient temperature is changed, the elastic compensation piece can be correspondingly deformed to drive the pointer to rotate clockwise or anticlockwise, and the pointer displacement distance produced by rotation is proportional to the pointer displacement distance produced by the influence of the ambient temperature on the pressure gauge, so that the precision error caused by the influence of the ambient temperature on the pressure gauge is corrected.
Description
(1) technical field
The utility model relates to a kind of tensimeter.
(2) background technology
In use all there be the influence of an environment temperature to tensimeter indicating value precision in ordinarily manometer, when the every reduction of environment temperature or increase by 10 degrees centigrade (normal serviceability temperature between 20 degrees centigrade to 25 degrees centigrade), manometric precision will reduce or increase that (the pressure survey indicating value was higher when environment temperature was high more than 0.4%, the pressure survey indicating value was on the low side when environment temperature was low), at north cold area, the oil oil field, the refinery workshop, all there are the high and cold or high heat of environment temperature in spinning workshop and printing and dyeing enterprise or the like, and tensimeter is difficult to measure an accurate pressure value in these environment.
(3) summary of the invention
In order to overcome existing manometric above-mentioned deficiency, the utility model provides a kind of high-precision pressure table that remedies environment temperature to the band temperature compensation of gauge measurement influence.
The technical scheme in the invention for solving the technical problem is: a kind of high-precision pressure table with temperature compensation, comprise watchcase, be provided with movement, gauge hand and bourdon tube in the described watchcase, described movement is provided with machine mandrel, described bourdon tube is connected with described machine mandrel, also be installed with a fixed bin in the described machine mandrel, the compensation elastic component is arranged in the described fixed bin, one end and the described fixed bin of described compensation elastic component are affixed, and the other end of described compensation elastic component is connected with described gauge hand.
Further, described compensation elastic component is the Cyclotron bimetallic strip.
During gauge measurement, bourdon tube drives machine mandrel, and machine mandrel drives fixed bin, and fixed bin drives the compensation elastic component, and the compensation elastic component drives gauge hand, and gauge hand is aimed at the corresponding scale of index dial and read pressure measuring value.When environment temperature changes, the compensation elastic component can corresponding produce deformation and drive pointer clockwise or be rotated counterclockwise, the pointer displacement distance of its rotation and tensimeter pointer displacement distance influenced by ambient temperature is directly proportional, thereby has remedied tensimeter trueness error influenced by ambient temperature.
The beneficial effects of the utility model are: can remedy the measuring error that produces because of temperature factor, realize high precision.

Fig. 1 is a structural representation of the present utility model.
Fig. 2 is a partial sectional view of the present utility model.
(5) embodiment
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
With reference to Fig. 1, Fig. 2, a kind of high-precision pressure table with temperature compensation, comprise watchcase 1, be provided with movement 2, gauge hand 3 and bourdon tube in the described watchcase 1, described movement 2 is provided with machine mandrel, and described bourdon tube is connected with described machine mandrel, also be installed with a fixed bin 4 in the described machine mandrel, in the described fixed bin 4 the compensation elastic component is arranged, an end and the described fixed bin 4 of described compensation elastic component are affixed, and the other end of described compensation elastic component is connected with described gauge hand 3.In the present embodiment, described compensation elastic component is a Cyclotron bimetallic strip 5.
During gauge measurement, bourdon tube drives machine mandrel, and machine mandrel drives fixed bin 4, and fixed bin 4 drives Cyclotron bimetallic strip 5, and Cyclotron bimetallic strip 5 drives gauge hand 3, and gauge hand 3 is aimed at the corresponding scale of index dial and read pressure measuring value.When environment temperature changes, Cyclotron bimetallic strip 5 can corresponding deformation produces and drives gauge hand 3 clockwise or be rotated counterclockwise, the pointer displacement distance of its rotation and tensimeter pointer displacement distance influenced by ambient temperature is directly proportional, thereby has remedied tensimeter trueness error influenced by ambient temperature.
