Abstract
The utility model discloses the pressure balanced Underwater Pressure sensor of a kind of rolling film chip, belong to sensor technical field, comprise housing and enclosure interior is divided into two chambeies and the rolling diaphragm be tightly connected with inner walls; The housing wall of compression chamber inside and compression chamber is respectively arranged with pressure transducer and differential pressure pickup, the housing wall of intake antrum offers inlet opening; Rolling diaphragm lower end is provided with the pallet be affixed with it, and extended in the direction vertical with its card of pallet have at least two to the L shape cursor slide of pallet extension, and inner walls offers the chute matched with L shape cursor slide.Measure two kinds of pressure respectively and improve measuring accuracy, the especially measuring accuracy of slight pressure, and adopt pallet to drive rolling diaphragm to compress to compression chamber, avoid hydraulic pressure excessive and easily cause diaphragm impaired, increasing its serviceable life.
Description
Technical field
The utility model relates to sensor technical field, in particular to the pressure balanced Underwater Pressure sensor of a kind of rolling film chip.
Background technology
Underwater Pressure sensor is widely used in the hydrospace detections such as tide detection, underwater robot job position mensuration; to the detection of the Underwater Pressures such as ocean; especially the detection of large pressure under deep-marine-environment; sensor must bear and measure the large hydraulic pressure at deep-sea; the change of hydraulic pressure can be measured again; this is that existing subsea pressure detects the difficult problem faced, and existing sensor is larger for the measuring error of the change of hydraulic pressure.
Utility model content
The purpose of this utility model is that providing one to bear measures large pressure, Measurement accuracy slight pressure can change the pressure balanced Underwater Pressure sensor of rolling film chip required, to solve the problem again.
For realizing the utility model object, the technical scheme of employing is: the pressure balanced Underwater Pressure sensor of a kind of rolling film chip, comprises housing and enclosure interior is divided into two chambeies and the rolling diaphragm be tightly connected with inner walls; Two chambeies of enclosure interior are respectively intake antrum and compression chamber, the housing wall of compression chamber inside and compression chamber is respectively arranged with pressure transducer and differential pressure pickup, the housing wall of intake antrum offers inlet opening; Rolling diaphragm lower end is provided with the pallet be affixed with it, extended in the direction vertical with its card of pallet have at least two to the L shape cursor slide of pallet extension, inner walls offers the chute matched with L shape cursor slide, and chute is arranged along the direction vertical with pallet card.
Further, described pallet is metal tray.
Further, described L shape cursor slide is two and distributes along pallet radial symmetry.
The beneficial effects of the utility model are, slight pressure change is measured by differential pressure pickup, i.e. compression chamber and extraneous pressure differential, reflect the slight pressure change of water pressure fluctuations, large pressure measured by pressure transducer, detect compression cavity pressure, the i.e. actual pressure of water, measure two kinds of pressure so respectively and improve measuring accuracy, especially the measuring accuracy of slight pressure, rolling diaphragm balancing water pressure, and adopt pallet to drive rolling diaphragm to compress to compression chamber, avoid hydraulic pressure excessive and easily cause diaphragm impaired, increasing its serviceable life and measurement range.
Accompanying drawing explanation
Fig. 1 is the cut-open view of the pressure balanced Underwater Pressure sensor of rolling film chip that the utility model provides.
Embodiment
Also by reference to the accompanying drawings the utility model is described in further detail below by specific embodiment.
Fig. 1 shows the pressure balanced Underwater Pressure sensor of rolling film chip that the utility model provides, and comprises housing 1 and is two chambeies with by housing 1 interior separation and the rolling diaphragm 2 be connected with housing 1 inner wall sealing; Two chambeies of housing 1 inside are respectively intake antrum 11 and compression chamber 12, the housing wall of compression chamber 12 inside and compression chamber 12 is respectively arranged with pressure transducer 4 and differential pressure pickup 5, the housing wall of intake antrum 11 offers inlet opening 14; Rolling diaphragm 2 lower end is provided with the pallet 3 be affixed with it, extended in the direction vertical with its card of pallet 3 have at least two to the L shape cursor slide 31 of pallet 3 extension, housing 1 inwall offers the chute 13 matched with L shape cursor slide 31, and chute 13 is arranged along the direction vertical with pallet 3 card.Pallet 3 is supported in housing 1 by the L shape cursor slide 31 be supported in chute 13.
L shape cursor slide 31 is preferably two and along the distribution of pallet 3 radial symmetry, pallet 3 is metal tray.
During use, by hawser or subsea equipment, sensor is placed into pressure region to be measured, during placement, water enters intake antrum 11 from inlet opening 14, and under the effect of water pressure, pallet 3 drives rolling diaphragm 2 to move in housing 1.When pallet 3 moves, diaphragm rolls along housing 1 inwall and pallet 3 outer wall, and the resistance in this process is very little, and rolling diaphragm 2 can move to compression chamber 12 direction, thus compression.Steadily, large pressure measured by pressure transducer 4, detects pressure, the i.e. actual pressure of water in compression chamber 12; Slight pressure change measured by differential pressure pickup 5, i.e. compression chamber 12 and extraneous pressure differential, reflects the slight pressure change of water pressure fluctuations.
The foregoing is only preferred embodiment of the present utility model, be not limited to the utility model, for a person skilled in the art, the utility model can have various modifications and variations.All within spirit of the present utility model and principle, any amendment done, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
