Abstract
The utility model provides a temperature transmitter with immersed liquid metal. A technical scheme is that the temperature transmitter comprises a transmitter body, that the bottom of the transmitter body is connected with a probe sleeve and an outer sleeve, that mercury liquid is filled in a gap between the probe sleeve and the outer sleeve, that a sealing ring is arranged between the liquid and a connecting screw nut. The temperature transmitter has a following effect. The mercury liquid is filled between the probe sleeve and the outer sleeve such that the temperature of a measured medium is transmitted by a probe in virtue of a characteristic of high heat transfer coefficient of the mercury. Therefore, measured temperature and actual temperature are consistent such that measurement accuracy is improved.
Description
Technical field
The utility model relates to temperature test instrument, is specifically related to liquid metals immersion temperature transmitter.
Background technology
The temperature transmitter that temperature test is used at present generally adopts sleeve pipe mode that temp probe is stretched in tested medium, first outer tube is welded on the container or tube outer wall of tested medium, outer tube is the blind pipe of an end opening, the outer tube that is threaded for probe sleeve that contains temp probe, but, between the probe sleeve that contains temp probe and outer tube, can not contact, because if produce contact, sleeve pipe cannot inject in outer tube, diametric(al) and length direction all need to install reliably than the less ability of outer tube, the problem that such mounting means brings is: between probe sleeve and outer tube, just have space and have air to exist, we know, the coefficient of heat conductivity of air is extremely low, be unfavorable for that the temperature between temp probe and measured medium is unified, also with regard to remote effect measuring accuracy.
Summary of the invention
In order to overcome the deficiency of background technology, the utility model provides liquid metals immersion temperature transmitter, adopts the way of contact of liquid metals to address the above problem by pipe.
The technical solution of the utility model is: liquid metals immersion temperature transmitter, comprise probe sleeve and outer tube that transmitter body, transmitter body bottom connect, in space between probe sleeve and outer tube, be filled with mercury metal liquid, between mercury metal liquid and attaching nut, be provided with O-ring seal.
The utlity model has following beneficial effect: by fill mercury metal liquid between probe sleeve and outer tube, make probe by the temperature of the high feature transmission measured medium of the heat transfer coefficient of mercury metal, record temperature and dut temperature and reach unified, improved measuring accuracy.
brief description of the drawings:
Accompanying drawing 1 is structural representation of the present utility model.
1-transmitter body in figure, 2-attaching nut, 3-O-ring seal, 4-probe sleeve, 5-outer tube, 6-mercury metal liquid.
embodiment:
Below in conjunction with accompanying drawing, the utility model is described in further detail:
As shown in Figure 1, liquid metals immersion temperature transmitter, comprise probe sleeve 4 and outer tube 5 that transmitter body 1, transmitter body 1 bottom connect, in space between probe sleeve 4 and outer tube 5, be filled with mercury metal liquid 6, between mercury metal liquid 6 and attaching nut 2, be provided with O-ring seal 3, O-ring seal plays sealing mercury metal and makes it can not evaporate and play heat insulation effect, and probe can not changed because of outside climatic environment.
Filling liquid mercury metal makes the heat conduction between probe and measured medium more direct, eliminate the problem of the air impact temperature conduction in conventional mounting method space, make probe by the temperature of the high feature transmission measured medium of the heat transfer coefficient of mercury metal, record temperature and dut temperature and reach unified, improved measuring accuracy.
