Abstract
The utility model provides a thermocouple verifying unit. Be provided with the ceramic vessel in the high temperature furnace, be equipped with in the ceramic vessel thermocouple with the fixed point metal block, the thermocouple pass through the two -conductor line respectively with temperature monitor and buzzer connection. The utility model discloses utilize the sensing temperature value of fixed point melting of metal temperature value demarcation thermocouple to this precision of proofreading the thermocouple. Suitable device as proofreading the thermocouple is used.
Description
Technical field
The utility model provides the device of fields of measurement, specifically thermopair verifying unit.
Background technology
For testing equipment, repeatability and the accuracy of temperature parameter are significant, and conventional temperature survey is with thermopair and infrared measurement of temperature, but cause thermocouple location to change due to unpredictable factor, temperature parameter drifts about, impact test progress or unstable product quality.The method determination device temperature parameter of usual employing two mutual comparisons of thermopair, but thermocouple readings is relevant with factors such as thermopair rigging positions, it itself is a relative value, and when being difficult to guarantee to proofread, strictly can repeat the position of thermopair at every turn, therefore, this method determination device temperature has certain limitation, can affect repeatability and the accuracy of device temperature.
Summary of the invention
In order to proofread the precision of thermopair, the utility model provides thermopair verifying unit.This device, by arranging ceramic vessel in high temperature furnace, places thermopair and fixed point metal, by hummer sounding and temperature indicator displays temperature value in ceramic vessel.Solve the technical matters that thermocouple temperature measurement value is demarcated.
The scheme that the utility model technical solution problem adopts is:
In high temperature furnace, be provided with ceramic vessel, at ceramic vessel built with thermopair and fixed point derby, thermopair is connected with temperature indicator and hummer respectively by two-conductor line.
Good effect, the utility model utilizes fixed point melting temperature metal value to demarcate the temperature sensor value of thermopair, proofreads the precision of thermopair with this.The suitable application of installation as check and correction thermopair.
Accompanying drawing explanation
Fig. 1 is structural drawing of the present invention
In figure, 1. temperature indicator, 2. hummer, 3. thermopair, 4. fix a point derby, 5. two-conductor line, 6 ceramic vessels, 7. high temperature furnace.
Embodiment
According to the figure, be provided with ceramic vessel 6 in high temperature furnace 7, at ceramic vessel built with thermopair 3 and fixed point derby 4, thermopair is connected with temperature indicator 1 and hummer 2 respectively by two-conductor line 5.
Use procedure of the present utility model:
The two-conductor line being installed with porcelain ring is placed in the bottom of ceramic vessel; its upper cover upper porcelain slice; ceramics is placed fixed point derby; the ceramic vessel connected, near fixed point metal, is put into high temperature furnace by thermocouple temperature measurement end, opens high temperature furnace power supply and starts to heat up; when metal molten, wire is connected; hummer sounding, this temperature is fixed point melting temperature metal, i.e. set point temperature; The now indicating value of immediate record temperature indicator reading and thermopair.After high temperature furnace cool to room temperature, change other fixed point metals, other temperature spots of check and correction thermopair.
Know-why:
Specific melting point metal is fixing, when special metal melts, is waiting synthermal lower thermopair that temperature value is shown, by illustrating that value and melting temperature metal value are compared, regulates the Temperature displaying value of temperature indicator, thus the precision of check and correction thermopair.
