Abstract
The utility model discloses a thermostatic bath, which includes a bath body (1) which is a single cavity, and a stirring propeller (2) connected with an electric motor (3) which is mounted in the bath body (1). The utility model is characterized by simple structure, low cost, uniform and stable temperature of liquid medium in the bath body, little temperature difference, little temperature fluctuation, etc., the use effect is good, and technical indexes fully measure up to the national standards.
Description
Technical field
The utility model relates to a kind of device that is used for the proving temperature measurement instrument, especially a kind of calibration cell.
Background technology
The effect of calibration cell is by the temperature of liquid medium in the control cell body, makes to be used for proving temperature meter equitemperature measurement instrument in the workspace by temperature stabilization, even in the workspace.Existing calibration cell is generally two cavitys, upper and lower side between the cavity has circulation passage, and middle cavity is as the workspace, and is provided with motor and paddle in the middle chamber bottom, circulation by liquid medium in the cell body from middle cavity to the both sides cavity, thus reach the purpose of uniform temperature.The disadvantage of this groove is that maximum temperature difference and the temperature fluctuation in the cell body is bigger, and result of use is not ideal enough.And the structure more complicated, cost is also higher.
The utility model content
Technical problem to be solved in the utility model provides maximum temperature difference and little and simple in structure, the lower-cost calibration cell of temperature fluctuation in a kind of groove, to overcome the deficiencies in the prior art.
The technical scheme that the utility model adopted, it comprises cell body (1), and this cell body (1) is single chamber, and paddle (2) is housed in cell body (1), and paddle (2) connects motor (3).
Cell body in above-mentioned (1) shape can be square, rectangle, cylindrical, ellipse or triangle.
In above-mentioned cell body (1), be provided with well heater (4), be used for to the liquid medium heat temperature raising.
Also be provided with cooling tube (5) in cell body (1), cooling tube (5) connects refrigeration compressor, is used for the liquid medium cooling to cell body (1).
Compared with prior art, the utility model adopts the cell body in single chamber, and workspace and flat-temperature zone are integrated, not only relatively simple for structure, cost is lower, and the temperature of liquid medium is even, stable in the cell body, the temperature difference and temperature fluctuation are little, and the constant temperature effect is more satisfactory.Technical indicator is up to state standards fully.
Description of drawings
Accompanying drawing 1 is a structural representation of the present utility model.
Embodiment
Embodiment 1 of the present utility model: as shown in Figure 1, it comprises cell body 1, and cell body 1 adopts stainless steel to make, and is shaped as cylindrically, also can do squarely, rectangle, ellipse, triangle or other shapes.This cell body 1 is single cavity configuration, and paddle 2 is housed in cell body 1, and paddle 2 connects motor 3.Stirring arm 2 is installed in the middle position of cell body 1, perhaps is installed in the sidewall locations of cell body 1.Paddle 2 is used to stir the liquid medium in the cell body 1, keeps cell body 1 interior temperature even.Liquid medium can be any one in water, oil or the alcohol.Temperature for ease of liquid medium in the control cell body 1 also is equipped with well heater 4 and cooling tube 5 in cell body 1, cooling tube 5 connects refrigeration compressor.
Claims (4)
1. calibration cell, it comprises cell body (1), it is characterized in that: cell body (1) is single chamber, and paddle (2) is housed in cell body (1), paddle (2) connects motor (3).
2. calibration cell according to claim 1 is characterized in that: being shaped as of cell body (1) is square, rectangle, cylindrical, ellipse or triangle.
3. calibration cell according to claim 1 is characterized in that: be provided with well heater (4) in cell body (1).
