Facilitate fixing wireless pressure to become and send deviceTechnical field
The present invention relates to pressure transmitter field, be specifically related to facilitate fixing wireless pressure to become and send device.
Background technology
Pressure transmitter refers to be output as the pressure sensor of standard signal, it is a kind of instrument of accepting pressure variations and being converted in proportion standard output signals, the physical pressure such as gas, the liquid parameter that it can be experienced load cell is transformed into the signal of telecommunication of standard, and to supply with, the secondary meters such as indicator alarm, recorder, adjuster are measured, instruction and procedure regulation. Current pressure transmitter is wired connection mostly, need data line to realize the transmission of signal, so not only make data receiver inconvenience, and especially when this pressure transmitter is in relatively far away when outdoor, not only will expend a large amount of data wires, and relatively more easily there is signal Receiver Problem in data wire. Therefore, some wireless pressure transmitters have also been there are successively at present, still, existing wireless pressure transmitter price is relatively expensive, although really there are some problems in wired pressure transmitter, consider for price, most of users still select wired pressure transmitter.
Summary of the invention
The object of the present invention is to provide and facilitate fixing wireless pressure change to send device, this pressure transmitter improves the inner chamber of existing wired pressure transmitter, existing wireless module is placed in inner chamber dexterously, and do not affect the general layout of original inner chamber, install very conveniently, can effectively reduce the cost of wireless pressure transmitter.
The present invention for achieving the above object, realizes by the following technical solutions:
Facilitate fixing wireless pressure to become and send device, comprise that cavity and two are separately positioned on the end cap at cavity two ends, the lower end of cavity is provided with for cavity being fixed on to the connection base on pipeline, on cavity, be also provided with display for showing variable parameter and the connector for inlet wire, the middle part of described cavity is provided with parting bead, the two ends of described parting bead are provided with cushion block, cushion block, parting bead are all close to the inwall of cavity, the interior arc that is also provided with of described cavity, arc and cushion block are positioned on same perpendicular.
In this programme, by existing wired pressure transmitter is improved, especially cavity is improved, do not changing on the basis of original pressure transmitter interior, by parting bead, cushion block and arc are set in cavity, wireless module can be placed in cavity just, under the effect of end cap, wireless module is clamped, is fixed on the space place forming between end cap and arc, simultaneously, do not block inside cavity space due to parting bead and arc, therefore the heat in cavity can well be scattered and disappeared with the opening on end cap or pore; Cushion block, on the basis of playing a supporting role, is exceeded and is contacted with wireless module, makes the components and parts of wireless module can not be subject to too much compressing, and wireless module has been played to certain protective effect, also makes the heat of wireless module scatter and disappear preferably simultaneously.
Further, as preferred version, described cavity is cylindric, and the shape of cross section of cushion block is fan-shaped, and the center line of cavity is perpendicular to the cross section of cushion block.
Further, as preferred version, a described cushion block equates with the thickness of parting bead and the thickness of arc.
Further, as preferred version, two sides that described parting bead is relative with arc are parallel to each other.
The present invention compared with prior art, has the following advantages and beneficial effect:
(1) the present invention improves by the cavity to existing wired pressure transmitter, can hold existing wireless module, like a cork wired pressure transmitter is become to wireless pressure transmitter, compare current wireless pressure transmitter, price is lower, practicality is stronger, can meet the demand of general user to wireless pressure transmitter.
(2) the present invention by arranging parting bead, cushion block and arc in the cavity of existing wired pressure transmitter, by with the mating reaction of end cap, not only realize well wireless module fixing in cavity, also do not affect the radiating efficiency of wireless module simultaneously, can effectively improve the repacking space of wired pressure transmitter to wireless pressure transmitter.

Detailed description of the invention
Below in conjunction with embodiment, the present invention is described in further detail, but embodiments of the present invention are not limited to this.
Embodiment:
As Fig. 1, shown in Fig. 2, device is sent in the fixing wireless pressure change of convenience described in the present embodiment, comprise that cavity 1 and two are separately positioned on the end cap 2 at cavity 1 two ends, the lower end of cavity 1 is provided with for cavity being fixed on to the connection base 3 on pipeline, on cavity 1, be also provided with display 4 for showing variable parameter and the connector 5 for inlet wire, the middle part of cavity 1 is provided with parting bead 6, the two ends of parting bead 6 are provided with cushion block 7, cushion block 7, parting bead 6 is all close to the inwall of cavity 1, the interior arc 8 that is also provided with of cavity 1, arc 8 is positioned on same perpendicular with cushion block 7, wireless module is placed in cavity 1, and with cushion block 7, arc 8 is affixed, now the end cap 2 at cavity 1 two ends is screwed on, wireless module is fixed on after cavity 1, wireless module connects with the interior corresponding power line of cavity 1, existing wired pressure transmitter can easily be adapted as wireless pressure transmitter, wireless module is available circuit plate structure.
As preferably, the cavity 1 of the present embodiment is cylindric, and the shape of cross section of cushion block 7 is fan-shaped, and the center line of cavity 1 is perpendicular to the cross section of cushion block 7.
A cushion block 7 of the present embodiment equates with the thickness of arc 8 with the thickness of parting bead 6.
Parting bead 6 two sides relative with arc 8 of the present embodiment are parallel to each other.
The above, be only preferred embodiment of the present invention, not the present invention done to any pro forma restriction, and any simple modification, equivalent variations that every foundation technical spirit of the present invention is done above embodiment, within all falling into protection scope of the present invention.
