Abstract
The utility model relates to a pressure transducer, comprising a casing. The utility model is characterized in that a corrugated pipe and a micro switch are arranged in the casing. One end of the corrugated pipe is provided with an opening which is communicated with the measured medium, and the other end sealed. The micro switch is arranged in the homolateral casing, and the opening end of the corrugated pipe is fixedly connected with the casing. The utility model has the advantages of simple structure, and flexible action. The utility model can not be damaged when the utility model is in the operating state for long time. The utility model is suitable for measuring various gas, liquid pressure, or vacuum.
Description
The utility model relates to a kind of pressure transducer.
At present, with the pressure in the pressure vessel as the detector switch amount, thereby realize equipment such as automatic washing machine, the cell culture incubator etc. of control purpose automatically, the detection working pressure sensor of pressure, existing pressure transducer, as be used in glued membrane formula pressure transducer on the automatic washing machine, it only is suitable for the work of the discontinuity of short time, long time continuous working can make glued membrane aging, causes control malfunctioning.
The purpose of this utility model provides a kind of novel pressure sensor, and it can overcome existing shortcoming in the prior art.
The purpose of this utility model is achieved in that it comprises a housing, it is characterized in that being equipped with in the housing corrugated tube and microswitch, corrugated tube one end opening, communicate with measured medium, other end sealing, and microswitch is housed in side body, corrugated tube openend and housing fixedly link.
During work, measured medium enters corrugated tube, make and produce pressure in its chamber, and under the effect of this pressure, make corrugated tube generation elastic deformation and elongate or shorten, make the microswitch action, produce electric signal, adjust the distance of microswitch and corrugated tube end, the scope of controlled pressure is changed accordingly.
The utility model is simple in structure, is active in one's movements, and can be in running order for a long time and can not produce damage, the utility model goes for the measurement of all gases, fluid pressure or vacuum.
The utility model is described in further detail below in conjunction with accompanying drawing.
Fig. 1 is the structure cut-open view of a kind of specific embodiment of the utility model.
Fig. 2 is second kind of example structure synoptic diagram of housing of the present utility model and base connecting mode.
Fig. 3 is second kind of example structure synoptic diagram of the mounting means of the utility model microswitch.
5 is housings among Fig. 1, corrugated tube 8 and microswitch 3 are housed in the housing, the lower end of corrugated tube 8 is an open type, is welded with pad 7, and O-ring seal 6 is housed, by base 9 O-ring seal and pad are pressed on the housing, realize fixing between corrugated tube and the housing, the corrugated tube upper port is sealed, and microswitch 3 is housed on it, microswitch is installed in the Jiong shape slide block 1, and the position of adjusting it by screw 2 and 4 is also fixing.
Be to adopt flange to connect between Fig. 2 middle shell 5 and the base 9, between O-ring seal 6 is housed, the corrugated tube lower end is welded with pad 7, is pressed between the flange.
Microswitch 3 is fixed in the slide block 1 among Fig. 3, and the adjustment of slide block 1 is by screw 2, and catch 10 is housed on the screw.
