What thermocouple sensor output voltage values reflected is the difference of its measuring junction temperature and cold junction temperature, and thermocouple sensor cold junction is conventionally away from dut temperature point.By the measurement to cold junction temperature, carry out the actual temperature value of computation and measurement point, this process is called cold junction compensation.
The measuring method of conventional cold junction temperature is adopt cold junction terminal box or directly cold junction introduced in measurement mechanism.Cold junction terminal box is that cold junction tie point and temperature probe are all placed in terminal box, because temperature probe, cold junction tie point are in same temperature field, so the output-response of temperature probe the temperature of cold junction tie point.
Conventionally connector is comprised of plug and socket, and socket is fixed on measurement mechanism shell, and plug is connected with sensor wire.During measurement, plug is docked with socket, can complete being connected of sensor and measurement mechanism.
In thermocouple measurement application, common connector is all connected to plug 2 by cable by the output of the output of one or more thermocouple sensors 1 and the interior cold junction temperature survey sensor 6 of cold junction box 5.In use, plug 2 is docked with the socket 3 being installed on measurement mechanism 4, realize being connected of one or more thermocouple sensors 1 and cold junction temperature survey sensor 6 and measurement mechanism 4, connected mode is as Fig. 1.
Three, utility model content:
The utility model, in order to solve the weak point in above-mentioned background technology, provides the connector construction of the even cold junction temperature survey sensor of a kind of integrated thermal electric.
For achieving the above object, the technical solution adopted in the utility model is: the connector construction of the even cold junction temperature survey sensor of a kind of integrated thermal electric, comprise thermocouple sensor, plug, socket, measurement mechanism and cold junction temperature survey sensor, described cold junction temperature survey sensor is integrated thermometric device, described integrated thermometric device adopts single power supply, comprise three lines, described plug is connected with socket, socket is fixedly arranged on the shell of measurement mechanism, on described plug, be connected with cable grip, plug is connected with thermocouple sensor cable, it is characterized in that: described cold junction temperature survey sensor is arranged in cable grip, three lines of described cold junction temperature survey sensor are welded on three contact pins on connector plug 2 tops.
It is fixing that described weld adopts silica gel to fill.
Compared with prior art, advantage and the effect that the utlity model has are as follows: in some specific occasion, due to limited space, adopt the utility model, thermocouple cold junction survey sensor can be placed in to the inner space of plug, utilize the plug cable grip attached with it to form an enclosure space, played the function of cold junction box in traditional structure, can save the position that cold junction terminal box is installed, structure is small and exquisite, easy to use.
Four, accompanying drawing explanation:
