Abstract
The utility model discloses a kind of resistance to heavy called putting-into-type liquid level meters, including liquid level gauge head and cable, the cable is connected with liquid level gauge head, pass through encapsulation process at the cable crust and the line outlet of liquid level gauge head, through-hole is offered on circuit board in the liquid level gauge head, one group of conducting wire in the cable is attached with through-hole, the utility model carries out binding with the through-hole on the circuit board in liquid level gauge head by using the conducting wire in cable and connect, through-hole is opened at the top of circuit board, it is provided by this root conducting wire and additional pulls power, the weight of liquid level gauge head whole is avoided to act on cable and the crust in liquid level gauge head exit, effectively prevent rear cable crust of long duration from causing drainage due to pullling relaxation, it plays a very good protection to internal circuit board.
Description
Technical field
The utility model is related to instrument, instrumentation field, specially a kind of resistance to heavy called putting-into-type liquid level meter.
Background technology
Called putting-into-type liquid level meter is based on the surveyed fluid pressure principle proportional to the height of the liquid, using advanced isolation
Type spreads silicon-sensitive element or ceramic capacitive pressure sensitive sensor is made, and static pressure is converted to electric signal, using temperature
Degree compensation and linear amendment are converted to a kind of pressure of measurement liquid level of standard electric signal (generally 4~20mA/1~5VDC)
Sensor, it is suitable for the liquid of the various media of the systems such as petrochemical industry, metallurgy, electric power, pharmacy, water supply and sewage, environmental protection and industry
Position measures.Exquisite structure, simple adjustment and flexible mounting means are user easily using providing a convenient.
But since called putting-into-type liquid level meter needs are put into water for a long time, provided by cable and pull power, and liquid
The total weight of position meter head is acted on the cable crust at its line outlet, is when the time limit of input is longer, at this
Cable crust is probably pullled relaxation, is caused drainage, is caused short circuit to the circuit board in liquid level gauge head in this way.
Utility model content
The problem of for background technology, the utility model provide a kind of resistance to heavy called putting-into-type liquid level meter.
To achieve the above object, the utility model provides the following technical solutions：A kind of resistance to heavy called putting-into-type liquid level meter, including
Liquid level gauge head and cable, the cable are connected with liquid level gauge head, at the line outlet of the cable crust and liquid level gauge head
By encapsulation process, through-hole is offered on the circuit board in the liquid level gauge head, one group of conducting wire in the cable and through-hole
It is attached.
As a kind of preferred technical solution of the utility model, the conducting wire being attached with the through-hole is using cable
Redundancy in line.
As a kind of preferred technical solution of the utility model, the through-hole is opened at the top of circuit board.
As a kind of preferred technical solution of the utility model, the through-hole is connected with conducting wire by the way of binding
It connects.
Compared with prior art, the utility model has the beneficial effects that：The utility model is by using leading in cable
Line carries out binding with the through-hole on the circuit board in liquid level gauge head and connect, and through-hole is opened at the top of circuit board, passes through this root conducting wire
There is provided it is additional pull power, avoid the weight of liquid level gauge head whole from acting on cable and the crust in liquid level gauge head exit,
It effectively prevents rear cable crust of long duration from causing drainage due to pullling relaxation, internal circuit board is played well
Protective effect.
Description of the drawings
Fig. 1 is the utility model surface structure schematic diagram；
Fig. 2 is the utility model circuit board and wire connection diagram；
In figure：1- liquid level gauge heads；2- cables；3- circuit boards；4- through-holes；5- conducting wires.
Specific implementation mode
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without making creative work
The every other embodiment obtained, shall fall within the protection scope of the present invention.
Embodiment：
It please refers to Fig.1 and Fig. 2, the utility model provides a kind of resistance to heavy called putting-into-type liquid level meter, including liquid level gauge head 1 and electricity
Cable 2, the cable 2 are connected with liquid level gauge head 1, pass through sealing at 2 crust of cable and the line outlet of liquid level gauge head 1
Processing offers through-hole 4 on the circuit board 3 in the liquid level gauge head 1, one group of conducting wire 5 in the cable 2 and through-hole 4 into
Row connection.
The utility model is carried out by using the conducting wire 5 in cable 2 with the through-hole 4 on the circuit board 3 in liquid level gauge head 1
Binding connection, through-hole 4 are opened in the top of circuit board 3, by this root conducting wire 5 provide it is additional pull power, avoid liquid level gauge head 1 complete
The weight in portion acts on cable 2 and on the crust in 1 exit of liquid level gauge head, effectively prevents 2 crust of rear cable of long duration
Drainage is caused because pullling relaxation, is played a very good protection to internal circuit board 3.
In addition to the use of normal wires in cable is not influenced, what the conducting wire 5 being attached with the through-hole 4 used
It is one group of redundancy in cable 2.
The above is only the preferred embodiment of the utility model only, is not intended to limit the utility model, all at this
All any modification, equivalent and improvement etc., should be included in the utility model made by within the spirit and principle of utility model
Protection domain within.
