Summary of the invention
The purpose of this utility model provides a kind of liquid tension mensuration thermostat that can overcome above-mentioned defective, accuracy rate height, excellent working performance.Specifically:
Comprise that pedestal, axle are movably arranged on sample stage and thermostat module on the pedestal, wherein sample stage adopts Heat Conduction Material to make, it is provided with the sample cave, it is characterized in that: the cooling assembly that thermostat module adopts polylith to be made by N type, two kinds of semiconductor materials of P type, its huyashi-chuuka (cold chinese-style noodles), hot side are all fitted with bottom surface, sample cave and are fixedly connected, and its positive and negative power end correspondence connects power supply through temperature control switch K.
Described liquid tension is measured and is used thermostat, and fitting around the huyashi-chuuka (cold chinese-style noodles) of thermostat module, hot side and the sample cave is fixedly connected, and the degree of depth in sample cave is not less than the degree of depth of fluid to be measured, is convenient control, and sample stage is provided with handgrip.
Described liquid tension is measured and is used thermostat, set up thermostat, comprise the temperature sensor, A/D converter, comparison control module and the driver module that are installed in the sample stage, wherein driver module adopts relay, its contact is a switch, the output terminal of temperature sensor connects the comparison control module through A/D converter, and relatively the output terminal of control module is succeeded electric apparatus coil.
Its principle of work is: be equipped with the cooling assembly that polylith is made by N type, two kinds of semiconductor materials of P type in the sample stage that adopts Heat Conduction Material to make, the temperature in cave is adjusted the positive and negative power end of thermostat module and being connected of power supply per sample, when its positive power source terminal energized, its hot side is just heated to the sample cave, otherwise absorbing and cooling temperature, the temperature constant that guarantees the sample cave is in setting value.After the sample cup that fills fluid to be measured was put into sample cave a period of time, the temperature of fluid to be measured was just invariable, is not subjected to the influence of environment temperature, guarantee the accuracy of measurement result, and simple in structure, cheap, temperature adjustment speed is fast, and thermograde is little, and is easy to operate.
Description of drawings
Fig. 1 is the structural representation of the utility model embodiment;
Fig. 2 is the principle of work block diagram that the utility model has attemperating unit.
Embodiment
Among the figure: 1, sample stage 2, pedestal 3, sample cave 4, thermostat module 5, temperature sensor 6, A/D converter 7, comparison control module 8, driver module 9, handgrip 10, stationary shaft 11, heat radiator
In the embodiment shown in fig. 1, sample stage 1 adopts aluminium matter Heat Conduction Material to make, wherein be provided with two sample caves 3, the bottom surface in sample cave 3 and thermostat module 4 are fitted and are fixedly connected, temperature by its control sample cave 3, and then the temperature of control fluid to be measured, temperature sensor 5 is installed in the temperature that is used for test sample cave 3 in the sample stage 1.Thermostat module 4 adopts two cooling assemblies of being made by N type, two kinds of semiconductor materials of P type, its hot side of cooling assembly in the middle of is wherein fitted with the bottom surface in sample cave 3 and is fixed, its bottom is provided with a stationary shaft 10 plug-in mounting axles and is fixed on the pedestal 2, be looped around its huyashi-chuuka (cold chinese-style noodles) of another piece around this cooling assembly and fit with the bottom surface in sample cave 3 and fix, and the bottom of this cooling assembly is fixed with heat radiator 11.
When its positive power source terminal during through temperature control switch K energized, its hot side is just heated to sample cave 3, on the contrary absorbing and cooling temperature.When the temperature constant in sample cave 3 when setting value is measured, fluid to be measured is put into the sample cave 3 that configures temperature in advance, control handgrip 9 makes sample cave 3 aim at analyzers, treats to begin to measure after the temperature constant to get final product.
Embodiment shown in Figure 2 sets up attemperating unit on basis embodiment illustrated in fig. 1, driver module 8 adopts relay, temperature sensor 5 is installed in the temperature that is used for test sample cave 3 in the sample stage 1, its output terminal connects comparison control module 7 through A/D converter 6, relatively the output terminal of control module 7 is succeeded electric apparatus coil, and the contact K of relay connects the positive and negative power end of thermostat module 4.The temperature signal that temperature sensor 5 detects outputs to comparison control module 7 after A/D converter 6 converts digital signal to, compare judgement by itself and setting value, and output control signals to driver module 8, triggers its action.When the temperature in sample cave 3 is lower than setting value, temperature control switch K is in 1 position, the positive power source terminal energized of thermostat module 4, its hot side is just heated to sample cave 3, on the contrary driver module 8 actions, temperature control switch K is in 2 positions, the negative power end energized of thermostat module 4, absorbing and cooling temperature, the temperature constant that makes sample cave 3 is in setting value, guarantee the accuracy of measurement result
