Description
Technical field
This utility model relates to armarium and Laboratory Instruments field, is specifically related to metal bath optical temperature measurement device.
Background technology
Metal bath, also known as dry bath device, is a kind of conventional medical laboratory's terminal process equipment.This instrument can configure multiple module, can be widely applied to the preservation of sample, the preservation of various enzyme and the degenerative treatments of reaction, nucleic acid and protein, PCR reaction, the denaturation of electrophoresis and serum solidification etc..In the process, temperature control precision and the time of control are most important, are directly connected to the accuracy of experimental data.To the most accurate temperature control, it is necessary for obtaining fast and accurately the temperature of heated sample.
Existing metal bath, many employing contact type temperature sensors indirectly obtain the temperature by thermal modules.First, for accuracy and the sensitivity of thermometric, temperature sensor needs are fully contacted with heating board.Secondly, temperature sensor and heating board carry out sufficient heat exchange, make temperature sensor and heating plate reach thermal balance.Finally, read the electric parameter of temperature sensor, the electric parameter of temperature-sensing element is converted to the temperature value of correspondence, thus the temperature information of necessity is provided to control unit, coordinate control unit that heating board is carried out accurate temperature controlling.
Existing metal bath is heated module temperature by contact indirect mode measurements, it is impossible to quickly for control system offer by the real time temperature information of thermal modules.Because to obtain by thermal modules real time temperature information, then have to make to be rapidly achieved between temperature sensor and heating board thermal equilibrium state.There is certain space between typical temperature sensor and heating board, cause heat balance time between them to increase.Although other conduction material can be filled in installation process to accelerate thermal balance speed, but compared with heating board self-heating speed, still cannot synchronize completely.Thus reduce the temperature control sensitivity of system.
Secondly, existing metal bath passes through contact indirect mode thermometric, and indirectly measurement is by the temperature of thermal modules, but measures heating board temperature.Only when heating board, temperature sensor, it is fully achieved thermal balance by thermal modules three, could obtain by the accurate temperature information of thermal modules.Although being heated, module bottom surface contacts with heating board end face, but its structures shape heating board heating rate with cannot be accomplished Complete Synchronization by thermal modules heating rate, when heating board reaches design temperature, the module temperature that is heated is slightly below design temperature, place different thermal capacity by thermal modules time, its temperature difference is also not quite similar；Equal modules, under different ambient temperatures, in heating process, its heating board there is also difference with the temperature gap of the intermodule that is heated.
Finally, existing metal bath temperature sensor is difficult to install and change.In order to improve the accuracy of thermometric, need to imbed in heating board temperature sensor, simultaneously need to insert appropriate Heat Conduction Material between the space between sensor and heating board, to improve its thermal balance speed, reduce the temperature difference of temperature sensor and heating board.Owing to temperature sensor is buried in heating board, when temperature sensor changed by needs, in heating board aperture, residual packing is difficult to clear up, and causes the new temperature sensor cannot normal mounting.
