Abstract
It the utility model is related to magnetic induction liquid level field, and in particular to a kind of magnetic induction fluid level transmitter probe, the probe include：Metal tube and the pcb board being sealed in inside metal tube, the pcb board is provided with some sulculuses, pad is provided with the both sides of each sulculus, the sulculus is built-in with tongue tube, the pin of tongue tube is flushed and is welded on the pad with the pad, tongue tube can be so placed in groove, pin is just concordant with pad, directly welded, so as to solve above-mentioned bent angle process easily cause tongue tube fracture scrap, or pin loosen cause subsequently to use loose contact and bent angle process cumbersome, reduction production efficiency the problem of.
Description
Technical field
It the utility model is related to magnetic induction liquid level field, and in particular to a kind of magnetic induction fluid level transmitter probe.
Background technology
In the existing stage, the probe internally provided tongue tube module of magnetic induction fluid level transmitter and precision resistance, and have metal tube close
Envelope.When external magnetic ball float changes with liquid level, relevant position tongue tube will be closed and turned on so that the resistance value hair of detecting head output
Changing, then by circuit conversion into 4-20mA.In conventional detection head manufacturing process, tongue tube both ends by artificial bent angle into
After 90 degree, insert in PCB welding hole, then weld；Whole PCB is put into metal tube afterwards, last encapsulating constitutes magnetic strength
The primary structure of inductive sensing device.The problem of being produced during this has：1 bent angle process easily causes tongue tube fracture and scrapped, or
Person's pin, which loosens, to be caused subsequently to use loose contact.2, bent angle process is cumbersome, reduces production efficiency.
Utility model content
The defects of the purpose of this utility model is to be directed to prior art and deficiency, there is provided a kind of magnetic induction fluid level transmitter
Probe, on the basis of original PCB, a sulculus is opened in centre, the both ends of groove set pad.So tongue tube can be placed on groove
Interior, pin is just concordant with pad, is directly welded, so as to solve the above problems.
To achieve the above object, the technical solution adopted in the utility model is：
A kind of magnetic induction fluid level transmitter probe,
The probe includes：Metal tube and the pcb board being sealed in inside metal tube, the pcb board are provided with some small
Groove, pad is provided with the both sides of each sulculus, the sulculus is built-in with tongue tube, and the pin of tongue tube flushes simultaneously with the pad
It is welded on the pad.
Further, the metal tube is sealed by encapsulating.
Further, the pcb board back side also includes being used for the pad for welding precision resistance.
After said structure, the utility model has the beneficial effect that：A kind of magnetic induction fluid level transmitter of the present utility model
Probe, on the basis of original PCB, a sulculus is opened in centre, the both ends of groove set pad.So tongue tube can be placed on groove
Interior, pin is just concordant with pad, is directly welded, and tongue tube fracture report is easily caused so as to solve above-mentioned bent angle process
It is useless, or pin loosens and cause subsequently to use loose contact and bent angle process cumbersome, the problem of reduction production efficiency.

Embodiment
The utility model is further described below in conjunction with the accompanying drawings.
As shown in Figure 1 to Figure 3, a kind of magnetic induction fluid level transmitter probe described in the utility model,
The probe includes：Metal tube 6 and the pcb board 1 being sealed in inside metal tube 6, pcb board 1 are provided with some small
Groove 2, pad 4 is provided with the both sides of each sulculus 2, sulculus 2 is built-in with tongue tube 3, and the pin of tongue tube 3 flushes simultaneously with pad 4
It is welded on pad 4.
Metal tube 6 is sealed by encapsulating.
The back side of pcb board 1 also includes being used for the pad 5 for welding precision resistance.
After said structure, the utility model has the beneficial effect that：A kind of magnetic induction fluid level transmitter of the present utility model
Probe, on the basis of original PCB, a sulculus is opened in centre, the both ends of groove set pad.So tongue tube can be placed on groove
Interior, pin is just concordant with pad, is directly welded, and tongue tube fracture report is easily caused so as to solve above-mentioned bent angle process
It is useless, or pin loosens and cause subsequently to use loose contact and bent angle process cumbersome, the problem of reduction production efficiency.
Described above is only better embodiment of the present utility model, therefore all according to described in the utility model patent application range
The equivalent change or modification done of construction, feature and principle, be included in the utility model patent application range.
