Abstract
The utility model relates to a surface temperature measuring vessel used for detecting a contact-type surface temperature sensor, which belongs to a test technology. The surface temperature measuring vessel comprises a temperature measuring tube (1) and a pressing device, wherein the temperature measuring tube (1) is a metal cylinder; the middle of the inner surface of the bottom of the temperature measuring tube (1) is provided with a rectangular sensor placing slot (2); and the pressing device comprises a beam (4) and 1 to 6 pressure lever assemblies arranged on the beam (4). The utility model can ensure that the temperature sensor and a heat-conducting object are in good contact, and thereby, the test error is lowered and the detecting accuracy is improved.
Description
Technical field
The utility model belongs to measuring technology, relates to a kind of surface temperature measurement ware that is used to examine and determine the contact surface temperature sensor.
Background technology
The method that provides according to vertification regulation, need the measured surface thermometer is put into a heat conduction object during calibrating contact surface temperature sensor, the heat conduction object is contacted with the Freezing point device that fills mixture of ice and water or constant temperature oven/groove, need the temperature of measuring by the conduction of heat conduction object.The heat conduction object generally is a copper sheet.Its shortcoming is: do not have stationary installation at the heat conduction object, can not guarantee that temperature sensor well contacts with the heat conduction object, introduce big test error easily, the accuracy of influence calibrating.
Summary of the invention
The purpose of this utility model is: provide a kind of temperature sensor that can guarantee to contact surface of good thermometric ware with the heat conduction object, to reduce test error, improve the accuracy of calibrating.
The technical solution of the utility model is: a kind of surface temperature measurement ware, it is characterized in that, it is made up of thermal bulb and hold down gag, thermal bulb is a metallic cylinder that lower port sealing, upper port are opened wide, the tube edge that one circle level is arranged in the upper port of thermal bulb, on the tube edge thermometer hole is arranged, there is the sensor mounting groove of a rectangle at the middle part of inside surface at the bottom of the thermal bulb tube, the bottom land thickness t=0.1～1mm of sensor mounting groove; Hold down gag is made up of crossbeam and 1～6 the depression bar assembly that is installed on the crossbeam, the two ends of crossbeam by screw retention tube along on, the depression bar assembly is by nut, spring and depression bar are formed, depression bar is the step axle of hypomere diameter greater than epimere, epimere end at depression bar is threaded, the epimere termination of depression bar upwards passes from the mounting hole on the crossbeam, nut is screwed on the screw thread of depression bar upper end, spring housing is at the epimere of depression bar, the lower surface of crossbeam is withstood in the upper end of spring, the step end face of depression bar is withstood in the lower end of spring, and the lower end of depression bar contacts with the bottom land of sensor mounting groove.
The utility model has the advantages that: it is good to guarantee that temperature sensor contacts with the heat conduction object, has reduced test error, has improved the accuracy of calibrating.Evidence, calibrating accuracy of the present utility model had improved more than 50% than originally.
