Abstract
The utility model relates to the field of the calibration of thermocouples, and particularly relates to a simple and easy constant-temperature detecting device for a reference end of a thermocouple. The simple and easy constant-temperature detecting device comprises a freezing-point thermostat. The simple and easy constant-temperature detecting device is characterized in that a sealing plug is arranged in the freezing-point thermostat; the outside diameter of the sealing plug is matched with the inside diameter of the freezing-point thermostat; a thermometer is arranged in the center of the sealing plug; a first glass tube is sleeved outside the thermometer; more than eight holes are concentrically and uniformly arranged around the thermometer; and second glass tubes communicated with air are arranged in the holes. The thermometer is a second-class standard mercurial thermometer with a minimal scale mark of 0.1 DEG C. Compared with the prior art, the simple and easy constant-temperature detecting device has the beneficial effects that the structure is simple, the simple and easy constant-temperature detecting device is convenient and reliable, the difficult problem that the constant-temperature control effect of the reference end of the thermocouple is poor is solved, the numerical reading is more convenient and quicker, and the temperature control is more accurate.
Description
Technical field
The utility model relates to the thermocouple calibration field, particularly a kind of simple and easy thermopair reference edge Constant Temperature Detection device.
Background technology
Stipulate that in the thermocouple calibration rules thermopair reference edge will put the cover glass pipe, being placed on from start to finish in the verification process and filling with mixture of ice and water, temperature is that the variation of its freezing point thermostat temperature can not be above ± 0.1 ℃ in 0 ℃ the freezing point thermostat.In this process, because ununified regulation, so thermopair is generally all inserted in the glass tube of thermostat dispersedly; With examining with reading; Its weak point is: reading is not directly perceived, and temperature control is poor, often can not accurately reach the technical indicator of national measurement verification requirement.
Summary of the invention
The purpose of the utility model provides a kind of simple and easy thermopair reference edge Constant Temperature Detection device, overcomes the deficiency of prior art, solves thermopair reference edge thermostatic control weak effect, and reading is a difficult problem intuitively not, makes temperature control more accurate.
For solving the problems of the technologies described above, the technical scheme of the utility model is:
A kind of simple and easy thermopair reference edge Constant Temperature Detection device; Comprise the freezing point thermostat, be provided with sealing-plug in the freezing point thermostat, sealing-plug external diameter and freezing point thermostat internal diameter coupling; The sealing-plug center is provided with thermometer; Thermometer outer casing glass tube one evenly is provided with the hole more than 8 with one heart around thermometer, is provided with logical empty glass tube two in the hole.
Said thermometer is that minimum calibration is 0.1 ℃ a second-class standard mercury thermometer.
Compared with prior art, the beneficial effect of the utility model is: simple in structure, convenient and reliable, solved the difficult problem of thermopair reference edge thermostatic control weak effect, and make reading more convenient, temperature control is more accurate.
Description of drawings
Fig. 1 is the utility model example structure synoptic diagram.
Among the figure: 1-freezing point thermostat 2-sealing-plug 3-thermometer 4-glass tube one 5-glass tube two 6-thermopair reference edge 7-mixture of ice and water
Embodiment
Be described further below in conjunction with the embodiment of accompanying drawing the utility model:
Seeing Fig. 1, is a kind of simple and easy thermopair reference edge Constant Temperature Detection device example structure synoptic diagram of the utility model, is provided with sealing-plug 2 in the freezing point thermostat 1; Sealing-plug 2 selections sealing effect of heat insulation is cystosepiment preferably; Sealing-plug 2 external diameters and freezing point thermostat 1 internal diameter coupling, sealing-plug 2 centers are provided with thermometer 3, thermometer 3 outer casing glass tubes 1; Evenly be provided with 12 holes with one heart around thermometer 3; Be provided with logical empty glass tube 25 in the hole, in order to satisfy the technical indicator of national measurement verification requirement, thermometer 3 is that minimum calibration is 0.1 ℃ a second-class standard mercury thermometer.
During use, 12 thermopair reference edges 6 are inserted respectively in the glass tube 25, opening part seals with absorbent cotton; Glass tube 1 all contacts with mixture of ice and water 7 with glass tube 25, during reading, thermometer 3 is mentioned; Read to finish and put down, keep temperature, this device appearance is attractive in appearance neat; Easy to use, high insulating effect, temperature is grasped more accurate.
