Abstract
The utility model relates to an oil diaphragm press head for measuring object weight. The utility model is characterized in that an elastic diaphragm and an oil transferring gravity signal are adopted, and a pole piston and a cylinder body is divided by an oil type cylinder body pole piston structure. The utility model has the advantages of simple structure, high precision transfer, reliable operation, long service life and convenient operation. The utility model doesn't need to be supplied with oil during the using process.
Description
The utility model relates to a kind of fluid diaphragm type pressure head of Measuring Object weight.
Have at present piezomagnetic, strain-type, capacitive etc. as the pressure head of weighing.The pressure head precision precision of piezomagnetic is not high, and the pressure head of other form awaits improving serviceable life.
The purpose of this utility model is that high primary instrument one pressure head of precision of design cooperates the weight of directly measuring object with high-precision sensor.
The utility model is achieved in that having oil pocket in cylinder body is used for filling fluid, oil sealing is lived and plunger and cylinder body are separated with elastic diaphragm.During check weighing object is placed on the plunger, the weight transfer of object is given the incompressibility of fluid owing to fluid, and the pressure transducer that is connected on the pressure head is measured the gravity of object.
Advantage of the present invention is simple in structure, and novel transmitting accuracy is very high, and fluid is sealed in the cylinder body to use in the phase and need replenish fluid, and is easy to use.
Accompanying drawing 1 is the structural drawing of pressure head
Accompanying drawings embodiment of the present utility model, elastic diaphragm 4 is contained between plunger 2 and the cylinder body 3, with bolt cylinder cap 1 and cylinder body 3 are tightened, plunger 2 does not directly contact with cylinder body 3, presses oil gun to cut down 5 and squeeze in the cylinder body 3 from unidirectional fluid 7 usefulness, squeezes in the process air and constantly discharges from 8 mouthfuls of pressure transducers, after fluid is full of, with pressure transducer 8, screw plug 6 is tight dead, and at this moment fluid is sealed in the cylinder body by elastic diaphragm 4.When action of gravity on plunger 2, plunger 2 with weight transfer to barrier film 4, by barrier film 4 again with weight transfer to fluid 7, pressure transducer is measured gravitational cue.
Claims (3)
1, fluid diaphragm type pressure head is characterized in that adopting the cylinder body plunger-type structure of fluid formula, does barrier film and sealing with resilient material, and plunger and cylinder body are separated.
2,, it is characterized in that on cylinder body, having oil pocket, be used for filling fluid according to the described pressure head of claim 1.
3,, it is characterized in that transmitting gravitational cue with elastic diaphragm and fluid according to the described pressure head of claim 1.
