Abstract
A pressure automatic compensator for underwater sensors belongs to a component of underwater sensors, and is applied to the force measuring and weighing technical field. An elastic body assembly 1 is arranged in a jacket assembly 3, and welded with the jacket assembly 3. An upper diaphragm 2 is respectively welded with the elastic body assembly 1 and the jacket assembly. A transmission rod 4 is in thread connection with the elastic body assembly 1. A lower diaphragm 6 is respectively welded with the transmission rod 4 and the jacket assembly 3. A bottom seat 5 is fixedly connected with the jacket assembly. The upper diaphragm 2 has the same area with the lower diaphragm 6. The utility model has the advantages that the pressure of sensors can be automatically compensated in water, the measurement precision of the sensors is improved and the product of the class can be applied to the occasions of higher requirements.
Description
Technical field
The utility model belongs to a kind of parts of underwater sensor, is applied to dynamometry and weighing technology field.
Background technology
Resistance strain type sensor is used very wide in dynamometry and weighing technology field, along with the introduction of domestic enterprise's technology and entering of external advanced enterprise, makes the technical merit of China in this field that raising at full speed arranged over past ten years.Dynamometry is the important parameter of general thermal technology, chemical process with weighing.From the influence condition of ergometry is diversified, and as experiment table is housed under water, experiment table needs to measure the variable quantity of some power when work, in such cases, sensor is had relatively high expectations, and mainly be to reject the error that causes because of hydraulic pressure.And present sensor is when carrying out underwater survey, and pressure is influential to measurement result, makes measurement result keep off actual value.
Summary of the invention
The utility model provides a kind of underwater sensor pressure autocompensation installation, and to solve moment sensor when carrying out underwater survey, pressure is influential to measurement result, makes measurement result keep off the problem of actual value.The technical scheme that the utility model is taked is: elastomeric components 1 be arranged in outer jacket member 3 and with its welding, upper diaphragm 2 welds with elastomeric components 1 and outer jacket member respectively, transmission rod 4 is threaded with elastomeric components 1, following diaphragm 6 welds with transmission rod 4 and outer jacket member 3 respectively, base 5 is fixedlyed connected with outer jacket member, and upper diaphragm 2 equates with the area of following diaphragm 6.Duty: in water, when being loaded into load W on the sensor, the power Q of sensor reflection is not only the pressure F that load W also has water, be Q=W+F, after adopting the pressure autocompensation installation, its below diaphragm and transmission rod F ' that is under pressure, pass upward the pressure F equal and opposite in direction that is subjected to top diaphragm and sensor through transmission rod, direction is opposite, cancels each other, promptly, Q=W+F+F ', F=-F ', Q=W. and then reduce the influence of pressure to sensor measurement power, make the result of sensor measurement power reach actual value, reduce measuring error.
Under water during dynamometry, because the existence of pressure, can certain influence be arranged to the result of sensor measurement, this device belongs to the pressure automatic compensation structure, and the diaphragm that two areas are equal is welded on outer jacket member and the sensor module respectively, on outer jacket member and the transmission rod.In water, when two diaphragms are subjected to equal and opposite in direction, during the opposite pressure of direction, this power is cancelled out each other by transmission rod.And then reduce the influence of pressure to sensor measurement power, and make the result of sensor measurement power reach actual value, reduce measuring error.
The utility model has the advantages that: this device quotes that the diaphragm that two areas equate is welded on outer jacket member and the sensor module respectively, on outer jacket member and the transmission rod.In water, when two diaphragms are subjected to equal and opposite in direction, during the opposite pressure of direction, this power is cancelled out each other by transmission rod.And then reduce the influence of pressure to sensor measurement power, and make the result of sensor measurement power reach actual value, reduce measuring error.Sensor can be carried out pressure in water because of its structure and compensate automatically, improve the measuring accuracy of sensor, can make the higher occasion of this type of product adaptation requirement, increase social benefit.
