Abstract
The utility model relates to a detachable temperature sensor, which is particularly suitable for measuring the cooling water temperature of a blast furnace. A protective shell is provided with a central blind hole; the left end of the central blind hole is provided with an internal thread; the outer cylindrical surface of the protective shell is provided with an external thread; a water-proof joint is fixed together with the protective shell through the internal thread; a temperature measuring element is inserted into a central hole of the protective shell; and the temperature measuring element extends into the inner bottom of the central blind hole of the protective shell.
Description
Technical field
The utility model relates to a kind of temperature sensor, is particularly suitable for the measurement of blast-furnace cooled water temperature.
Background technology
Blast-furnace cooled water temperature sensor usage quantity is more, because complex structure, price is higher, and because work under bad environment is fragile.The sensor of thermometric all is disposable embedding, if bad, has only all discarded.Owing to be disposable unit, use cost is higher.
Summary of the invention
In order to overcome the shortcoming of prior art, the utility model provides a kind of detachable temperature sensor, and it is simple in structure, and cost is low, can reuse.
The technical scheme that its technical matters of the utility model solution is taked is: the protection housing has central blind hole; The left end of central blind hole has internal thread; On the external cylindrical surface of protection housing external thread is arranged; Water joint is fixed through internal thread and protection housing, is installed with temperature element in the center pit of protection housing, and temperature element stretches into the central blind hole inner bottom part of protection housing.
1), simple in structure the utlity model has advantage:, cost is low; 2), can reuse reduction spare part cost.In the sensor use, no matter be lead wire fault or temperature element fault, because water joint is to be threaded with the protection housing, as long as take sensor apart, changing lead-in wire or temperature element can reuse; 3), sensor adopts two-wire system, compares former three-wire system, can simplify wiring, reduces fault.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the utility model is further specified.
Accompanying drawing is the utility model cut-open view.
Embodiment
Shown in accompanying drawing, protection housing 3 has central blind hole 6, and the left end of central blind hole 6 has internal thread 2, on the external cylindrical surface of protection housing 3 external thread 4 is arranged.Water joint 1 is fixing with protection housing 3 through internal thread 2, is installed with temperature element 5 in the center pit of protection housing 3, and temperature element 5 stretches into central blind hole 6 inner bottom parts of protection housing 3.
The material of said protection housing 3 and water joint 1 is a stainless steel.
