Using above-mentioned technical proposal, the utility model utilizes one end diaphragm pressure-sensitive medium of differential pressure pick-up, another terminal membrane
Piece is communicated with outside atmosphere, is realized outside and is breathed freely, reduces influence of the condensed water to product, improve the precision of measurement.
Description of the drawings
Fig. 1 is the structural schematic diagram of the utility model.
Specific implementation mode
As shown in Figure 1, the condensation-proof transmitter of the utility model comprising pedestal 1, connector 2, sensor connecting piece 5
And differential pressure pick-up 6.
Wherein, the concrete structure of differential pressure pick-up 6 may refer to China's practicality of Authorization Notice No. CN204479229U newly
Type patent, one side end face have outboard diaphragm exposed to the atmosphere, and another side end face has to be connect with sensor connecting piece 5
Inner side diaphragm.Differential pressure pick-up 6 is attached by welding with sensor connecting piece 5.Connector 2 is then located at sensing
Between device connector 5 and pedestal 1, one end is welded with sensor connecting piece 5, and the other end welds for pedestal 1, the outboard end of pedestal 1
There is reaction diaphragm on face.The side of differential pressure pick-up 6 has connector 8, is connect with display 9 by the connector 8.In the connector
In 8.In the present invention, 9 angle of display is adjusted to improve degree flexible for installation and facilitating, connector 8 is rotary joint.It connects
First 8 inner chamber interior sealing has circuit board and pressure-sensitive silicon chip (not shown).
In the present invention, connector 2 and sensor connecting piece 5 constitute connector, have connection in the connector
The medium runner of the inner side diaphragm of differential pressure pick-up 6 and the reaction diaphragm of pedestal 1, medium runner is interior to be filled with pressure-sensitive medium, example
Such as silicone oil, fluorocarbon oil, vegetable oil.And the oil filler pipe 3 of connection medium runner is also welded with the week of connector 2.This is oil-filled
Pipe 3 is flexible tube.The groove circumferentially extended is offered with the week of connector 2, and groove is embedded in after oil filler pipe 3 is flexible
In, and the guard circle 4 that can block groove is additionally provided on connector 2, which is rubber washer.Oil filler pipe 3 is using
After can along storing in groove and be covered by guard circle, play it is beautiful, be not easy to hide dirty effect.
In addition, causing to damage to prevent the rear end pressure-sensitive diaphragm with outside connection from contacting with sharps, differential pressure pick-up 6
End face outside on be additionally provided with the protection cap 7 for covering outboard diaphragm, there is osculum on the circumferential surface of protection cap 7.
Above is exactly the utility model condensation-proof transmitter, is had the following advantages that using the above structure：
1, using differential pressure pick-up one end diaphragm sensed media pressure, other end diaphragm is communicated with air, prevents condensed water
Product Precision is had an impact；
2, wiring board is enclosed in inside differential pressure pick-up, using the diaphragm and atmosphere of differential pressure pick-up, wiring board with
