Abstract
The utility model relates to an ultrasonic energy converter, in particular to a double-sensor ultrasonic energy converter, which comprises a sensor and an energy converter outer shell, wherein, a transmitting sensor is arranged inside a transmitting sensor outer shell, a receiving sensor is arranged inside a receiving sensor outer shell, and the transmitting sensor outer shell is connected with the receiving sensor outer shell through a connecting element. The utility model adopts an ultrasonic energy converter with a double-sensor structure, thereby overcoming the problem of the measuring blind area of the ultrasonic level meter. The utility model has the advantages of small measuring blind area, wide measuring range, high detection precision, good reliability, etc., thereby having the important practical value and wide popularization value.
Description
Technical field
The utility model relates to the ultrasonic transducer that a kind of ultrasonic material level meter uses, and particularly relates to a kind of dual sensor ultrasonic transducer.
Background technology
The ultrasonic transducer of ultrasonic material level meter use at present is the single-sensor transducer, inevitably like this brought immunity region for whole ultrasonic ripple level meter, the immunity region of ultrasonic material level meter is also referred to as ultrasonic material level meter " measurement blind area ", and we wish that " the measurement blind area " of ultrasonic material level meter is the smaller the better usually.But " blind area " of single-sensor structure ultrasonic material level meter is intrinsic, inevitably.The generation of measuring the blind area is because ultrasonic transducer is being subjected to the effect of high energy pulse wave excitation, produce the mechanical vibration of same frequency, when the high energy pulse wave excitation stops, because the mechanical vibration of inertia effect transducer do not stop, just be carved into mechanical vibration and stop constantly when the high energy pulse wave excitation stops, transducer can't receive the detection of reflected echo.So single-sensor transducer measurement range is less to be the ubiquitous problem of ultrasonic material level meter.
Summary of the invention
The technical problems to be solved in the utility model is to overcome existing single-sensor transducer can't receive detection of reflected echo, the less deficiency of measurement range immediately, and a kind of dual sensor transducer is provided.This dual sensor transducer in use, it is little to measure the blind area, antijamming capability is strong, measurement range is wide, the measuring accuracy height has good detection performance and practicality.
The technical scheme that its technical matters that solves the utility model adopts is: a kind of dual sensor ultrasonic transducer, comprise sensor and transducer enclosure, its structural feature is: described ultrasonic transducer is the combination of emission sensor and receiving sensor, described emission sensor places in the emission sensor shell, receiving sensor places in the receiving sensor shell, and emission sensor shell and receiving sensor shell link together with web member.
Adopt technique scheme, compare with the single-sensor transducer of prior art, the beneficial effects of the utility model are, have adopted the ultrasonic transducer of dual sensor structure, have overcome ultrasonic material level meter and have measured blind zone problem.The utlity model has that to measure the blind area little, measurement range is wide, the accuracy of detection height, and advantages such as good reliability have important practical value and promotional value widely.
Description of drawings
Fig. 1 is an outside drawing of the present utility model.
Fig. 2 is the cut-away view of Fig. 1.
Fig. 3 is the connection diagram of the utility model and ultrasonic material level meter.
Among the figure, emission sensor shell 1, coupling bolt 2, receiving sensor shell 3, emission sensor 4, receiving sensor 5, controller 6, cable 7.
Embodiment
Below in conjunction with drawings and Examples the utility model is described further.
Referring to Fig. 1, Fig. 2, emission sensor 4 is installed in the emission sensor shell 1, and receiving sensor 5 is installed in the receiving sensor shell 3.Emission sensor shell 1 and receiving sensor shell 3 are semicircular structure, the shell of two semi-circular structure is that emission sensor shell 1 and receiving sensor shell 3 upper and lower settings link together with coupling bolt 2, forms the dual sensor ultrasonic transducer of circular configuration.
Emission sensor 4 of the present utility model and receiving sensor 5 all adopt ultrasonic sensor, and the utility model can organically be connected with other controller and constitutes various measurement pick-up units.
In the embodiment shown in fig. 3, the utility model and controller 6 usefulness umbilical cable lines 7 are electrically connected, and form ultrasonic material level meter.
During work, the high-frequency impulse sound wave is sent by emission sensor 4, runs into testee (material) surface and is reflected and turns back, and the partial reflection echo is received sensor 5 and receives, and converts electric signal to.Owing to adopt the dual sensor structure, the high energy pulse wave excitation acts on emission sensor 4, when the high energy pulse wave excitation stops constantly,, receive reflection echo receiving sensor 5 all at initial (static) state because receiving sensor 5 is not received the effect of high energy pulse wave excitation at every turn.Therefore, receiving sensor 5 receives the detection of reflected echo at once.There is not immunity region in dual sensor transducer ultrasonic material level meter theoretically.
