Abstract
The utility model discloses a kind of monocrystalline-silicon pressure transducers with overload protection function, belong to sensitive components technical field.The utility model includes single pressure pedestal, chip, ceramic blanket, pedestal, protective device, isolation diaphragm, which is characterized in that the protective device is movable fixture, and the protective device is bellows;The bellows realizes the connection with single pressure pedestal by welding manner.When the utility model is had the advantages that by instantaneous pressure 1., the chip that can protect in monocrystalline-silicon pressure transducer is injury-free, enhances the shock resistance of monocrystalline-silicon pressure transducer;2. this product has many advantages, such as that structure is simple, easy for installation, low in cost.
Description
Technical field
The utility model relates to sensitive components technical field, specially a kind of monocrystalline silicon pressure with overload protection function
Force snesor.
Background technique
Existing monocrystalline-silicon pressure transducer generally includes single pressure pedestal, chip, ceramic blanket, bottom isolation diaphragm etc., the core
Piece is bonded in the ceramic blanket, and the said goods will cause the damage of chip when by greater impact power, and then influence pressure
The performance of sensor.In view of the above-mentioned problems, my company develops a kind of monocrystalline-silicon pressure transducer with overload protection function.
Summary of the invention
For disadvantages mentioned above existing in the prior art, the utility model is directed to the monocrystalline with overload protection function
Silicon pressure sensor;There is protective device, the protective device is bellows, and the bellows passes through welding in pressure sensor
Mode realizes the connection with single pressure pedestal.When sensor is by instantaneous pressure, above structure protects monocrystalline-silicon pressure transducer
In chip it is injury-free, enhance monocrystalline-silicon pressure transducer sensor shock resistance.
To achieve the goals above, the utility model adopts the technical scheme that
A kind of monocrystalline-silicon pressure transducer with overload protection function, including single pressure pedestal, chip, ceramic blanket, pedestal,
Protective device, isolation diaphragm, it is characterised in that: the protective device is movable fixture.
Preferably, the protective device is bellows.
Preferably, the bellows realizes the connection with single pressure pedestal by welding manner.
Compared with prior art, the utility model has the beneficial effects that 1. by instantaneous pressure when, can protect monocrystalline silicon
Chip in pressure sensor is injury-free, enhances the shock resistance of monocrystalline-silicon pressure transducer;2. this product has structure
Simply, the advantages that easy for installation, low in cost.
