Abstract
The utility model relates to a high temperature ultrasonic probe, which comprises a transducer, a suction cup connected with the transducer, and magnetic steel arranged on the suction cup. The utility model is mainly characterized in that the transducer casing comprises a contact head A, a heat elimination bar B and a mounting cavity C which are directly contacted with the wall of a container. The utility model solves the liquid level test problem when the container wall temperature is higher than 80 DEG C, thereby being applied to the test work of the external ultrasonic liquid level the high-temperature container.
Description
Technical field
The utility model relates to the tank fill level sensor, particularly a kind of external labeling type ultrasonic probe.
Background technology
The existing outer ultrasonic probe that pastes can only be applicable to vessel wall temperature less than 80 ℃ situation, can't satisfy the measurement when the external labeling type liquid level of vessel wall temperature during greater than 80 ℃.Its fault of construction is not have thermal component, thereby can not solve pyrometric problem.
The utility model content
The purpose of this utility model provides a kind of vessel wall temperature that can be used for and implements the high temperature ultrasonic probe that liquid level is pasted ultrasonic measurement outward greater than 80 ℃ device.
The purpose of this utility model is achieved in that a kind of high temperature ultrasonic probe, comprises transducer and the sucker that is attached thereto, and magnet steel is housed on the sucker, and the housing of transducer is made of the contact head, heat-radiating rod and installation cavity three parts that directly contact with chamber wall.
The purpose of this utility model can also realize like this: the heat-radiating rod of housing is partly with heat radiator.The transducer inner structure is: piece under radiation head, piezoelectric ceramics, electrode slice, the transducer is housed in the installation cavity of housing, by the bolt that is with heat-shrink tube its assembling is linked, the both positive and negative polarity of electrode slice is drawn by cable, waters envelope by watering the envelope agent on every side; Watering the envelope agent is equipped with packing ring, spring, briquetting, sealing gasket outward successively and presses mother to compress and seal by joint; Radiation head is pressed on the inner plane that is adjacent under female pressure at the installation cavity of housing by couplant and at spring, joint.
The utlity model has following advantage: by on transducer housing, increasing the heat-radiating rod that length is L, select the heat-radiating rod of different length according to the height of vessel wall temperature, can make transducer that cavity temperature is installed reduces to below 80 ℃, thereby ultrasonic probe can be worked under the condition of high temperature, solved the difficult problem of current elevated temperature vessel level gauging.

Embodiment
High-temperature probe described in the utility model by piece 6 under transducer housing 1, bolt 2, piezoelectric ceramics 3, electrode slice 4, heat-shrink tube 5, the transducer, sealing gasket 7, cable 8, joint press female 9, water envelope agent 10, sucker 11, magnet steel 12, radiation head 13, packing ring 14, spring 15, briquetting 16 and form.
Transducer housing 1 is made of three parts: wherein A is a contact head, directly contacts with the elevated temperature vessel wall; B is a heat-radiating rod, and its outside can process some grooves, forms heat radiator, enlarges area of dissipation, and its length L is by the temperature decision of detected chamber wall; C is the transducer installation cavity, inner transducer element and the holddown spring etc. installed.
Heat-shrink tube 5 is enclosed within on the bolt 2, and bolt 2 is assembled piece under the transducer 6, piezoelectric ceramics 3, electrode slice 4, radiation head 13 and tighten up.Radiation head 13 end faces borrow joint to press the strength of mother 9 and spring 15 to be close on the transducer installation cavity plane by couplant.
Cable 8 connection electrode sheets 4.Watering envelope agent 10 waters and is enclosed in transducer inside, protection transducer and attached cable 8.Cable 8 passes packing ring 14, spring 15, briquetting 16, sealing gasket 7 and joint and presses female 9 to draw.Joint presses mother 9 internal thread to be tightened on the transducer housing 1, and transducer is compressed.Joint presses mother 9 external thread to be connected with the Explosion-proof host that the user provides.
Sucker 11 and transducer housing 1 are by being threaded and glueing joint; Be inlaid with magnet steel 12 on it, lean on the suction of magnet steel 12 that probe is fixed on the chamber wall.
