Specific embodiment
The utility model is described in further detail below in conjunction with attached drawing.
Embodiment 1:
A kind of external contactless liquid level prior-warning device, referring to Fig.1, the present apparatus are mounted with two ultrasonic waves including built-in
The probe cassette 3 of level sensor receives, the control box 2 of processing and driving output for signal, status indicator lamp 1 and corresponding
Connection cables 4.Wherein, it controls on box 2 and is provided with 3 Aviation Connectors J1, J2, J3, and above-mentioned Aviation Connector is all made of GX12
Aviation Connector.Probe cassette 3 is connected by connection cables 4 with the second Aviation Connector J2 controlled on box 2, and first on box 2 is controlled
Aviation Connector J1 is connected by connection cables 4 with status indicator lamp 1.The remaining third Aviation Connector J3 of control box 2 passes through connection
Cable 4 is connected with plug 5, and plug 5 is powered for connecting power supply for whole device.
Working principle is as follows: referring to Fig. 2 and Fig. 3, probe cassette 3 is made of two supersonic liquid level inductors S1, S2.Two
Supersonic liquid level inductor S1, S2 are popped one's head in using supersonic liquid level, can be penetrated steel plate transmitting and receiving signal within 10 millimeters, are not necessarily to
Contacted with liquid you can learn that the correspondence probe installation location in hermetically sealed can liquid whether there is or not.When coolant liquid changes in tank
When, supersonic liquid level inductor S1 issues signal.Control box 2 receives the signal of supersonic liquid level probe S1 after treatment, if
The signal control converting unit set in control box issues state output driving signal, and status indicator lamp 1 receives above-mentioned driving
Realize that condition monitoring shows and makes feedback after signal.Control driving exports corresponding clearing lamp and informs user's coolant liquid
State.The working condition of clearing lamp is divided into following three kinds of situations:
(1) when coolant liquid FC3283 is normal in tank, green indicator light L3 is bright.
(2) when coolant liquid FC3283 is lower than normal position in tank, yellow indicator lamp L4 is lighted, and early warning coolant liquid needs to mend
It fills.
(3) when coolant liquid FC3283 is close to minimum work liquid level in tank, red indicating light L5 is lighted, and coolant liquid will consume
To the greatest extent, it is necessary to supplement at once.Wherein coolant liquid FC3283 is perfluamine.
Referring to Fig. 3, after power supply is accessed by third Aviation Connector J3, the bright expression control box 2 of the first LED light L1 must establish the beginning by cable
Work.When the first supersonic liquid level inductor S1 and the second supersonic liquid level inductor S2 enter without signal, signal control
Converting unit processed driving red indicating light L5 red units light, and control box red indicating light L5 lights instruction, indicate at this time without
It senses corresponding liquid level, needs to add immediately.When the second supersonic liquid level inductor S2 induced liquid being mounted on tank body, warp
For Aviation Connector J2 input signal to control box 2, the second LED light L2, which lights instruction, signal input, and it is single to control signal control in box 2
Member driving yellow indicator lamp L4, which is lighted, indicates pot liquid missing.The incoming control of first supersonic liquid level inductor S1 inductive signal
Box 2, green indicator light L3 are lighted, while green indicator light L3 signal being driven to issue, and indicate that liquid level is normal.First Aviation Connector J1
It is connected to signal lamp, retains a buzzer signal, can be configured according to user demand.
Above-mentioned specific embodiment is only the explanation to the utility model, is not limitations of the present invention, this
Field technical staff can according to need after reading this specification makes modification to the present embodiment, but as long as practical new at this
All by the protection of Patent Law in the scope of the claims of type.
