Description
The utility model relates to a kind of ultrasonic probe, is meant a kind of external labeling type ultrasonic solution bit switch probe especially.Be applicable to tank fill level carried out non-cpntact measurement that it belongs to intelligent ultrasonic liquid level sensor technical field.
As everyone knows, in traditional ultrasonic solution bit switch, be the outer surface that is installed in chamber wall at a distance of 1.5 meters to 3 meters transmitting probe and receiving transducer with two,, be not easy to install and maintenance just because of two probes are independently parts and make this level switch structure comparatively complicated.Especially when two probes are not in same level height, will cause this level switch can not accomplish in time and accurately to send alarm switch amount signal.
The purpose of this utility model is at above-mentioned weak point, existing level switch structure is improved, provide a kind of simple in structure, be convenient to the not receptor diameter constraint of installation, reliable working performance and the scope of application, the external labeling type ultrasonic solution bit switch probe that transmitting probe and receiving transducer are united two into one.
The purpose of this utility model is realized by following technical scheme, it comprises shell (1), receiving sensor (2) and emission sensor (3), emission sensor (3) is housed in the inner chamber of receiving sensor (2), two sensors all are on same the common axis, establish one deck spacer sleeve (4) between the outer wall of the inwall of receiving sensor (2) and emission sensor (3); Receiving sensor (2) and emission sensor (3) one ends are affixed with reception base (5) and emission base (6) respectively, the other end links to each other with little gland (8) with big gland (7) respectively, bolt (9) passes big gland (7) and links to each other with emission base (6) with little gland (8) and emission sensor (3) inner chamber, fix with nut, receiving sensor (2) and emission sensor (3) are connected as a single entity; Shell (1) is sleeved on outside receiving sensor (2) and the emission sensor (3), is connected with reception base (5).
The purpose of this utility model can further be realized that also gap location is established O-ring seal (10) between reception base (5) and the emission base (6) by following technical scheme; Receive base (5) and establish O-ring seal (11) with shell (1) connecting place; Receiving sensor (2) and emission sensor (3) all adopt piezoelectric ceramics or piezoelectric crystal material to make; Spacer sleeve (4) adopts nonmetallic materials cast such as epoxy resin or polyurethane to form; Establish a fairlead (12) on the shell (1); Draw two signal wires respectively on receiving sensor (2) and the emission sensor (3); Shell (1) one end is established a circle external thread (13).
Ultrasonic solution bit switch probe is installed in container (16) outside surface by support (14), that is needs the position of spacing alarm.
The utility model has the advantages that to have overcome the weak point that exists in the prior art to have that simple in structure, installation and maintenance are convenient, reliable working performance and a scope of application characteristics such as receptor diameter constraint not.This level switch probe is owing to be installed in container outer surface, and it is not subjected to pressure medium, temperature, proportion and corrupting influence, is specially adapted to the liquid level warning of inflammable, explosive occasion pressure vessel and non-pressure vessel.
In conjunction with the accompanying drawings and embodiments the utility model is described further:
Fig. 1 is an external labeling type ultrasonic solution bit switch sonde configuration synoptic diagram
Fig. 2 is that external labeling type ultrasonic solution bit switch probe is installed and technical schematic diagram
In the described external labeling type ultrasonic solution of the present embodiment bit switch probe, emission sensor (3) is housed in the inner chamber of receiving sensor (2), two sensors all are on same the common axis, establish one deck spacer sleeve (4) between the outer wall of the inwall of receiving sensor (2) and emission sensor (3); Receiving sensor (2) and emission sensor (3) one ends are affixed with reception base (5) and emission base (6) respectively, the other end links to each other with little gland (8) with big gland (7) respectively, bolt (9) passes big gland (7) and links to each other with emission base (6) with little gland (8) and emission sensor (3) inner chamber, fix with nut, receiving sensor (2) and emission sensor (3) are connected as a single entity; Shell (1) is sleeved on outside receiving sensor (2) and the emission sensor (3), is connected with screw with reception base (5).
Gap location is established O-ring seal (10) between reception base (5) and the emission base (6); Receive base (5) and establish O-ring seal (11) with shell (1) connecting place; Receiving sensor (2) and emission sensor (3) all adopt piezoceramic material to make; Spacer sleeve (4) adopts the epoxide resin material cast to form; Establish a fairlead (12) on the shell (1); Draw two signal wires respectively on receiving sensor (2) and the emission sensor (3); Shell (1) one end is established a circle external thread (13).
The utility model installation and know-why are as follows:
Ultrasonic solution bit switch probe (17) is installed in container (16) outside surface by support (14), that is needs the position of spacing alarm, and is close to container (16) outside surface.Support (14) connects agent by epoxy bond and permanent magnet (15) is fixed on container (16) outside surface, ultrasonic solution bit switch probe (17) is screwed on the support (14), makes container (16) the outside surface position that contacts with emission base (6) and reception base (5) scribble one deck couplant.
Ultrasonic solution bit switch probe (17) is close to container (16) outside surface by support, that is need the position of spacing alarm, between the secondary instrument (21) in ultrasonic solution bit switch probe (17), transmitter (19) and the pulpit, adopt transmission line (18) and transmission line (20) to carry out the information transmission respectively.Ultrasonic solution bit switch probe (17) is to be used to launch ultrasonic pulse and to receive the echo reflection pulse, and be processed into alarm switch amount signal by transmitter (19), transmitter (19) adopts blast resistance construction, be assembled with adaptation therein, the information that transmitter (19) provides shows automatically and reports to the police through secondary instrument (21), secondary instrument (21) adopts high performance unit sheet, and is provided with RS-232 interface.
