Abstract
The utility model discloses a metal tube wall temperature admeasuring apparatus which includes a flexible circuit board, a temperature sensor chip connected with the flexible circuit board and a main circuit board; the flexible circuit board is thermally coupled with a metal sheet in a whole body; the main circuit board is also provided with a second temperature sensor; a microprocessor arranged on the main circuit board receives and processes the data measured by the temperature sensor chip and the second temperature sensor, and can transmit the data to a display module; and an insulating layer is arranged on the flexible circuit board and the temperature sensor chip. The metal tube wall temperature admeasuring apparatus has the advantages of simple structure, accurate measurement, good stability and small temperature change caused by the outside.
Description
Technical field
The utility model relates to a kind of temperature measuring set, more particularly, is a kind of temperature measuring set of measuring the metal pipe-wall temperature.
Background technology
What the measuring channel temperature was with the most use at present is to measure temperature by thermopair being welded in tube wall, so not only bother, and can only disposablely use the sticking card sensor that thermopair bonding machine cost height, also useful thermistor are made, and also can only disposablely use, the folder type thermometer that cost height, also useful thermopair are made, but exist low precision, when especially dut temperature and environment temperature differed greatly, it was subjected to extraneous thermal effect very big.
The utility model content
In order to solve the problems referred to above that prior art exists, the utility model proposes a kind of metal pipe-wall temperature measuring set, it is subjected to extraneous thermal effect little, is the metal pipe-wall temperature measuring set of a precision height, good stability.
The utility model can be solved by the following technical programs:
A kind of metal pipe-wall temperature measuring set, comprise a flexible circuit board, a temperature sensor chip that is connected with this flexible circuit board and a main circuit board, a described flexible circuit board and a sheet metal thermal coupling are one, also be provided with second temperature sensor on the described main circuit board, microprocessor that is provided with on the described main circuit board and circuit receive and handle described temperature sensor chip and second data that temperature sensor measurement arrives, and can be transferred to a display module; Described flexible circuit board and temperature sensor chip are provided with a thermofin.
As preferred embodiment of the present utility model:
Be one by a heat conduction glue-line thermal coupling between flexible circuit board described in the utility model and the sheet metal; Described thermofin is silica gel and Kapton adhesive tape; Described sheet metal is a copper sheet; The shell that also comprises a tool display screen, described sheet metal are arranged on the surface of contact of shell and metal pipe-wall; Described shell adopts clampable, can be clipped on the metal pipe-wall that needs to measure.
Since adopt above technical scheme, a kind of metal pipe-wall temperature measuring set of the present utility model, and its flexible circuit board with the tool temperature sensor chip is thermally coupled on the sheet metal, has guaranteed precision and the stability measured; Adopt heat-conducting glue, can reduce the thermal impedance of sensor and tested tube wall to greatest extent; By the design of second temperature sensor, it is a thermosensitive resistance type sensor, and it can solve the measuring error that causes heat to run off and cause because of sheet metal, and this thermosensitive resistance type sensor is responsible for measuring the temperature of surrounding enviroment.
