Abstract
The utility model discloses a telemetering thermocouple which comprises a thermocouple wire, a sheath and a conjunction box, wherein the sheath is connected with the conjunction box, the cold end of the thermocouple wire is connected to a terminal row in the conjunction box, and the hot end of the thermocouple wire is inserted in the sheath. The telemetering thermocouple further comprises a ceramic shield filled with silicone oil, wherein the conjunction box is arranged in the ceramic shield, the coupling end of the conjunction box and the sheath is provided with a seal bulkhead, a wireless signal emitter is arranged outside the ceramic shield, and the input end of the wireless signal emitter is connected with the terminal row. Since the conjunction box is arranged in the ceramic shield filled with silicone oil, the cold end of the thermocouple wire is under a stable ambient temperature and a compensation lead is not needed. The temperature signal tested by the thermocouple wire is sent out through wireless signal, thereby ensuring stable operation of thermocouple and substantially lowering manpower and material resources for maintenance.
Description
Technical field
The utility model relates to area of thermocouples, is specifically related to a kind of teletransmission thermopair.
Background technology
Thermopair is a kind of temperature element commonly used in temperature measuring instrument, thermocouple wire one end that two different metals are made connects and composes hot junction, the other end does not contact the formation cold junction, when different with cold junction environment temperature of living in when hot junction, there will be electric potential difference between two thermocouple wires, electric potential difference changes with temperature difference geometric ratio; Thermopair generally extends to constant temperature enclosure by cold junction by compensating wire in use, to guarantee the accuracy of measuring.When the coke drum of oil refining enterprise moves, internal temperature can reach 600 degree, the tower wall is enclosed with heat-insulation layer, the insulation layer surface temperature is no more than 50 degree, and after the coke drum decoking, internal temperature only has tens degree, the tower wall can produce the phenomenon of expanding with heat and contract with cold, heat-insulation layer can produce displacement, is inserted in the compensating wire of the thermopair on the tower wall often because the movement of heat-insulation layer damages, and needs to drop into a large amount of manpower and materials and is safeguarded.
Summary of the invention
The technical problems to be solved in the utility model is to provide a kind of teletransmission thermopair, and the thermopair that can solve on current coke drum is guaranteed measurement accuracy with compensating wire, and compensating wire often damages, and causes safeguarding the problem had high input.
The utility model is achieved through the following technical solutions:
A kind of teletransmission thermopair, comprise thermocouple wire, sheath, terminal box, sheath is connected with terminal box, the cold junction of thermocouple wire is connected in the terminal row in terminal box, sheath is inserted in the hot junction of thermocouple wire, also comprises ceramic case, in described ceramic case, is filled with silicone oil, described set of terminal box is in ceramic case, and the link of described terminal box and sheath is provided with seal plug; Described ceramic case outside is provided with wireless signal transmitter, described wireless signal transmitter input end splicing ear row.
The further improvement of the utility model scheme is, described wireless signal transmitter comprises signal acquisition module and wireless signal transmitting module, signal acquisition module gathers the voltage signal of thermocouple wire hot junction output through terminal row, be converted into the input end that discernible input signal is sent to wireless signal transmitting module, wireless signal transmitting module sends input signal by the wireless signal form.
The utility model advantage compared with prior art is:
By set of terminal box in being full of the ceramic case of silicone oil, make the thermocouple wire cold junction substantially under stable environment temperature, do not need the using compensation wire, temperature signal thermocouple wire is measured by wireless signal transfers out, guarantee the thermocouple stabilization operation, greatly reduce the human and material resources of safeguarding and drop into.
The accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
