Abstract
The utility model relates to a force-sensitive sensor which is a torsion sensor displaying the torsion through bending moment deformation. A basal body of the sensor forms a butterfly-shaped symmetrical structure. A strain gauge of a precision resistor is pasted on the position of a cross symmetrical elastic body of the basal body of the sensor, and six holes on the periphery are used for installation and fixing. A circular hole on the middle of the basal body of the sensor is the hole for matching a torsion rod of a torsion transferring structure. The utility model also relates to a float barrel liquid level transmitter of a torsion sensor type. A float barrel component is hung on one end of a lever component, and one end of the lever component with an edge bearing is fastened to a lever seat by lever screws. The edge bearing falls on a cutting edge. The lever seat, a torsion tube, a torsion rod and a positioning ring obtain bottom closing and are welded into a whole. The other end of the torsion rod is fixedly connected with a middle core body of the basal body of the sensor through tight fixing screws. Positioning fastening screws pass through the six holes on the periphery of the basal body of the sensor to position the basal body of the sensor to a basal seat of the sensor, and the basal seat of the sensor is fixed on an installing body.
Description
Affiliated technical field
The utility model relates to a kind of force-sensing sensor and measurement instrument, reflects a kind of level gauging instrument of buoyancy variation with the variation of small moment of torsion.
Background technology
About the level gauging instrument, a kind of force-sensing sensor is used in float level transducer and carries out level gauging, in the middle of interior outer lever rib machine tool sealing is clamped in shaft-seal diaphragm, with the shaft-seal diaphragm is fulcrum, shaft-seal diaphragm is again simultaneously the inside and outside buffer action that rises of container, with the float level transducer of lever transmission buoyancy.The floating drum that interior lever is hung is invaded by liquid level not have the variation at position and buoyancy changes, and externally leverage changes in the power of force-sensing sensor, reaches liquid level and becomes the purpose of sending.But influenced by it bigger for precision during to the level gauging of pressure vessel, influence is more obvious under the indefinite condition of pressure, and main cause is that shaft-seal diaphragm is thinner, and distortion is bigger behind the pressurized, lever is moved axially cause that force-sensing sensor is stressed to change, measuring accuracy is affected.Like this, solve a pressure vessel level gauging, detect the sensitive element container inner pressure influence that is not stressed again, improve measuring accuracy.
Summary of the invention
Pressure vessel is carried out accurate level gauging, and the utility model provides a kind of torsion torque sensor and torsion torque sensor formula float level transducer, and the pressure influence of the container that is not stressed improves the level gauging precision.
The technical scheme that the technical matters that the utility model solves adopts is: the torsion torque sensor that shows torsion with the moment of flexure distortion.Structure and elastic body are as a whole, are referred to as sensor base, are the butterfly symmetrical structure.The precise resistance/strain meter is pasted on sensor base cross symmetric form elastic body position, the hole is used for installing and fixing in six peripheral holes, the torque arm that middle circular hole is the torsion transferring structure cooperates uses the hole, holding screw is the fixedly usefulness of torque arm of the middle circular hole of sensor base, and elastomeric thickness is decided according to the actual requirements.
Torsion torque sensor formula float level transducer, each binding site by flange, stay pipe, fixing body, torque tube, torque arm, locating ring, lever seat is a welded seal, forms buoyancy by float component, lever assembly, blade, lever seat, torque tube, torque arm, torsion torque sensor and converts torsion mechanism to.Float component is hung on lever assembly one end not to be had the variation at position to produce buoyancy to change owing to floating drum is invaded by liquid level, because lever assembly is anchored on the lever seat by the lever screw, lever seat with, torque tube, torque arm, the locating ring back run is connected to one, torque tube produces torsion and changes, this variation is passed to the middle core body of sensor base that is fastenedly connected by holding screw with the other end by torque arm, the location trip bolt pass peripheral six holes of sensor base with the sensor base installing and locating on sensor base, sensor base is fixed on the fixing body, torsion just acts on precise resistance/strain meter paster position like this, strainometer produces the moment of flexure modification, make the precise resistance/strain meter in transmission circuit, produce strain signal, by transmission circuit output desired signal.
