The test equipment of equal fields indispensability, for test and determine electrician, electronics and other products and material progress high temperature, low temperature or
Parameter and performance after the temperature environment variation of constant test.It therefore, is to guarantee to the calibration of environmental test device metering performance
Product quality provides the important means of authentic data in terms of design, the quality of product.
According to the technical requirements of " environmental test device temperature, humidity calibration specification " JJF1101-2003, arrangement measurement temperature
The measurement point of degree needs to be arranged on the fixation position in 3 layers of space；In the prior art, the temperature sensor of use is all flexible coupling
The temperature sensor of line needs sensor could be bundled in the fixed bit of calibrating standard requirement using the bracket with fixed point
It sets on a little, and the environmental test device being calibrated is typically all that a rectangular cabinet does not have fixed point.Therefore, use is existing
Technology cannot accurately arrange measurement point, be unable to satisfy the requirement that calibrating standard is accurately measured about setting fixed point.
In the prior art, the temperature sensor lead of use is generally four meters long, and each temperature sensor has 4 conducting wires；
For the environmental test device being calibrated, these conducting wires must all be penetrated from environmental test device measured hole or hermatic door could be complete
At measurement；These conducting wires not only cause environmental test device poorly sealed, and be routed it is cumbersome be easy to happen winding, need to spend
Many times arrange wiring, and working efficiency is very low.
Due to above many defects of the measuring device using the prior art, environmental test device can not be accurately measured
Environment temperature is not able to satisfy the technical requirements of " environmental test device temperature, humidity calibration specification " JJF1101-2003.
Summary of the invention
The utility model provides a kind of integrated temperature polling module, excessive to solve prior art measure traverse line, causes
Not the problems such as poorly sealed, flexible connecting line is not not easy to facility temperature measuring point rigidly, scene cannot quickly carry out detection operation.
The technical scheme adopted by the utility model is that: under 9 temperature sensors encapsulated by armouring stainless steel capillary
Portion is threadedly coupled by the mounting hole of upper housing with upper housing, has O shape between the lower part and upper housing inner surface of the temperature sensor
Sealing ring, the locking nut positioned at upper housing upper surface are connect with the lower thread of each temperature sensor respectively, which passes
Sensor is evenly arranged on upper housing upper surface, and circuit board is fixedly connected in the cavity of lower case by screw, wire jointing base welding
On circuit boards, the temperature measuring wire of each temperature sensor is connect with wire jointing base respectively, and the communication module on circuit board is also worn
Lower casing body sidewall is crossed, upper housing, lower case faying face have seal groove, and rectangular seal is placed in seal groove, upper housing, lower casing
Body is closely joined together by bolt.
The upper housing inner surface has seal groove, and the O-ring seals are placed in seal groove, the thickness of the O-ring seals
Degree is greater than the depth of seal groove；
The thickness of the rectangular seal is greater than the depth of seal groove；
9 temperature sensors include the temperature sensor one for being arranged in upper layer temperature measuring point, temperature sensor two,
Temperature sensor three and temperature sensor four are arranged in the temperature sensor five, temperature sensor six, temperature of lower layer's temperature measuring point
Spend the temperature sensor nine of sensor seven, temperature sensor eight and medium temperature measurement point.
The utility model has the advantages that structure novel, compact are integrally put into the temperature field of environmental test device, it can
To accurately measure the temperature change in temperature field, it is too many to solve prior art measure traverse line, influences environmental test device
Measurement data caused by overall tightness inaccuracy, flexible connecting line be not not easy to facility temperature measuring point rigidly, scene cannot be quick
The problems such as carrying out detection operation.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model；
Fig. 2 is the utility model section view.
Specific embodiment
