Description
Technical field
This utility model belongs to technology of instrument and meter field, and in particular to a kind of supersonic liquid level for penetrating tank skin measurement
Switch.
Background technology
Ultrasonic liquid level switch on sale on the market at present, including all producers of home and abroad, using the super of contact
Acoustic measurement principle.Using the ultrasonic liquid level switch of this measuring principle, the perforate on tank skin is needed, then ultrasound wave is passed
Sensor, is put in institute's perforate, and this ultrasonic sensor needs to contact with medium；By judge medium whether with ultrasonic sensor
Contact, realizes there is the measurement of liquid and aneroid to medium.
As ultrasonic sensor medium is contacted, easily cause the corrosion of ultrasonic sensor and damage；Impurity in medium,
The dirts such as precipitation, crystal are easily attached to the surface of ultrasonic sensor, easily cause ultrasonic liquid level switch wrong report or not
The phenomenons such as report.
Due to needing perforate, the difficulty increase such as the installation of instrument, maintenance, it is impossible to realize plug and play, that is, repair and use.If
Installing hole is not left in advance, cannot just carry out the installation and use of ultrasonic liquid level switch.And tank skin, open hole at more,
Potential safety hazard can be greatly increased.
Utility model content
In order to this utility model that solves the above problems provides a kind of ultrasonic liquid level switch for penetrating tank skin measurement, this
Ultrasonic liquid level switch is easier can Level Detection and control, cost performance is higher,
The technical solution of the utility model is：
A kind of ultrasonic liquid level switch for penetrating tank skin measurement, including ultrasonic liquid level switch, ultrasonic sensor, storage
Tank；The ultrasonic liquid level switch includes flush bonding processor, ultrasonic emitting circuit and ultrasound wave receiving circuit, embedded place
Reason device outfan is electrically connected by ultrasonic emitting circuit with ultrasonic sensor, and flush bonding processor input is passed with ultrasound wave
Sensor is electrically connected by ultrasound wave receiving circuit, and the ultrasonic sensor is affixed on storage tank outer wall.
The ultrasonic liquid level switch that tank skin measurement can be penetrated adopts advanced technology so that it is super that ultrasonic sensor is launched
Acoustic signals, can penetrate tank skin well, can be propagated well again in liquid；The ultrasound wave of this ultrasonic sensor transmitting
Signal, it is impossible to propagate in atmosphere, in slack tank state, because decaying in atmosphere very greatly, no signal is returned ultrasonic signal
Return；On the contrary when there is liquid status, propagation of the ultrasonic signal that ultrasonic sensor is launched through liquid, by ultrasound wave after return
Sensor is received；The comparison of ultrasonic signal when flush bonding processor is to two states, judges supersonic sensing
Whether device institute installation site completes signal output with the presence of liquid.
The beneficial effects of the utility model are：
（1）As this utility model can penetrate tank skin, belong to a kind of non-contact measurement instrument, possess non-contact measurement
Instrument is had the advantage that.
（2）Due to not contact medium, therefore it is not afraid of burn into and is not afraid of pollution, relative long service life, high precision.
（3）Due to being electronic instrument, without movable member, therefore also often safeguard without Jing and change adnexa without consumable accessory.
And the upgrading of electronic instrument, the replacement are also easy to so that measurement is reliable, cost is more saved.

Specific embodiment
In order that the purpose of this utility model, technical scheme and advantage become more apparent, with reference to embodiments, to this
Utility model is further elaborated.It should be appreciated that specific embodiment described herein is only to explain this practicality
It is new, it is not used to limit this utility model.
Below in conjunction with the accompanying drawings and specific embodiment is further described to application principle of the present utility model.
Embodiment 1
It is a kind of penetrate tank skin measurement ultrasonic liquid level switch, including ultrasonic liquid level switch 1, ultrasonic sensor 2,
Storage tank 3；The ultrasonic liquid level switch 1 includes that flush bonding processor 1-1, ultrasonic emitting circuit 1-2 and ultrasound wave receive electricity
Road 1-3, flush bonding processor 1-1 outfans are electrically connected by ultrasonic emitting circuit 1-2 with ultrasonic sensor 2, embedded
Processor 1-1 inputs are electrically connected by ultrasound wave receiving circuit 1-3 with ultrasonic sensor 2, and the ultrasonic sensor 2 is pasted
On 3 outer wall of storage tank.
As shown in figure 1, flush bonding processor 1-1, by ultrasonic emitting circuit 1-2, launches certain frequency and arteries and veins
Rush the signal of duration；This signal is converted to ultrasonic signal through ultrasonic sensor 2；Ultrasonic signal passes through tank skin, carries out
Propagate, reflection can also occur；The ultrasonic signal of reflection is received by ultrasonic sensor 2, is converted to the signal of telecommunication；This signal is passed through
Ultrasound wave receiving circuit 1-3, is embedded into formula processor 1-1 acquisition process；By the ultrasound wave for judging to have liquid and aneroid at tank skin
Signal is distinguished, output switch amount signal.
Specific embodiment of the present utility model is the foregoing is only, this utility model is not limited to, for
For those skilled in the art, this utility model can have various modifications and variations.It is all in spirit of the present utility model and former
Any modification, equivalent substitution and improvements made within then etc., should be included within protection domain of the present utility model.
