Abstract
The utility model discloses a constant temperature inserting device suitable for multi-probe calibration. The inserting device comprises an insert main body connected with a temperature control heating furnace body. The insert main body is provided with a plurality of inserting holes, one of which is provided with a standard platinum resistor. The other inserting holes are provided with isolation supports, which can be used to isolate temperature probes to be calibrated or thermocouples from each other. The utility model is advantageous in that by adopting the above mentioned technical scheme, the structure is simple, the use is convenient, the simultaneous calibration of a plurality of temperature probes or thermocouples can be realized; by using the isolation supports, the thermocouple probes in the same inserting hole can be uniformly and tidily arranged; the non-uniform temperature distribution caused by the non-uniform heat conduction can be greatly reduced, and the calibration accuracy can be improved; the production cost of the device is low, therefore the temperature device verification can be reduced to a great extent, the probability of calibration failure can be reduced, and the production efficiency can be improved.
Description
Technical field
The utility model relates to a kind of constant temperature insert arrangement that is applicable to many probe calibrations.
Background technology
Need to carry out the temperature checking to temperature device (such as high temperature furnace, sterilizing cabinet etc.) in industries such as food and medicine, metallurgy, mechano-electronics.The temperature checking probe that the most generally adopts both at home and abroad at present is thermopair.Because the thermopair environment for use is abominable, should calibrate before checking.Generally be that working heat galvanic couple (usually 10-15 root) and a standard thermal resistance are placed in the constant temperature inserted block of thermostatic oven simultaneously during calibration, the constant temperature inserted block provides an isothermal environment.The constant temperature inserted block of present commodity thermostatic oven configuration both domestic and external in order to adapt to most customer requirements, is the large scale jack, and each inserted block has 4-6 jack, and diameter is about 6-10mm.And the industrial thermocouple that above-mentioned industry is used, every of common diameter is approximately between the 2-3mm.Each jack must insert 3-4 root thermopair when causing calibrating like this, and these thermopairs quantity and space distribution in jack is irregular, can form heat conducting unevenness, has finally increased the uncertainty of checking, thereby has caused calibrating unsuccessfully.
The utility model content
Technical problem to be solved in the utility model provides a kind of multiplex (MUX) of being applicable to and already verifies the constant temperature plug-in unit of using thermocouple probe.
In order to solve the problems of the technologies described above, the technical scheme that the utility model adopts is: a kind of constant temperature insert arrangement that is applicable to many probe calibrations, described insert arrangement comprises the plug main body that is connected with the temperature control heating furnace body, be provided with some jacks at plug main body, be provided with standard platinum resistance in one of them jack, be provided with the isolation mount of mutually isolating waiing upon school temp probe or thermopair in all the other jacks.
Described isolation mount is cross.
Described plug main body material is fine copper, and the isolation mount material is teflon.
The utility model adopts technique scheme, and is simple in structure, easy to use, can realize how calibrating simultaneously with temp probe or thermopairs; The employing of isolation mount is evenly distributed neatly the thermocouple probe in the same jack, greatly reduces the non-uniform temperature distribution that non-homogeneous conduction hot in nature causes, and has improved the degree of accuracy of calibration.Low cost of manufacture of the present utility model has reduced the cost that temperature device is verified to a great extent, has also reduced the calibration probability of failure, has improved production efficiency.

Embodiment
As described in Fig. 1 to Fig. 3, a kind of constant temperature inserted block device that is applicable to many probe calibrations of the utility model, this device comprises a cylindrical inserts main body 1 that fine copper is made, the jack 5 that to be provided with 6 degree of depth in the inside of plug main body 1 be modal length 90%, insert reference standard platinum resistance 2 when being provided with for calibration in one of them jack 5, so that the reference standard temperature to be provided.Be provided with cruciform isolation mount 4 in other five jacks 5, with each jack 5 quadrisection, each jack 5 can insert 4 temp probes to be calibrated or thermopair 3.
The material of this plug main body 1 adopts the fine copper material, fine copper is heat-conduction coefficient the best in the industrial common metal, can greatly improve the homogeneity of Temperature Distribution in this constant temperature inserted block, and the remarkable temperature hysteresis that reduces in intensification, the temperature-fall period, be conducive to obtain rapidly uniform and stable calibration temperature field.
The utility model compared with prior art, when not adding the plug-in unit device, the mortality that 15 calibration of thermocouple are calibrated simultaneously is about about 20%, the time of primary calibration is about 45 minutes to one and a half hours.After adopting the utility model, the mortality of primary calibration drops to below 5%, and radial temperature difference can be controlled in below 0.1 ℃.
The above has carried out exemplary description to the utility model by reference to the accompanying drawings; obviously the utility model specific implementation is not subjected to the restriction of aforesaid way; as long as adopted the improvement of the various unsubstantialities that method of the present utility model design and technical scheme carry out; or without improving design of the present utility model and technical scheme are directly applied to other occasion, all within protection domain of the present utility model
