Abstract
The utility model relates to an ergometric/poidometric sensor for micro-loading which is composed of a corrugated diaphragm and an inductive linear displacement sensor. The ergometric/poidometric sensor for micro-loading is characterized in that a force transmitting block 4 is provided with a press head 1, the force transmitting block 4 is welded with a membrane 3 and connected with the thread adjusting rod part of an iron core 5, the iron core is inserted into the middle of an inductive coil 6 with a framework, the exterior of the coil is provided with a retainer 7, and the coil part of the displacement sensor is fixed to a base 9 by fixing screws 8. The ergometric/poidometric sensor for micro-loading has the advantages of minimal displacement and high measuring precision when in measuring, and corresponding electrical signals can be generated and output. The ergometric/poidometric sensor for micro-loading can be used in automatic detection systems and automatic control systems and widely applied in industry.
Description
The utility model relates to a kind of load and weighing cell that is used to detect small load, and it can be widely used in the precision measurement of industrial small load.
The sensor of forms such as existing loading force value survey sensor such as strain-type, piezomagnetic, type vibration wire is difficult to realize the measurement of the small load below 500 grams, realization also is very complicated on the technology reluctantly, can not apply industrial, existing a kind of weight beam that is used for small load measurement, it is when measuring, and the measured point produces bigger displacement, this is unallowed in many application scenarios, and do not have electric signal output, can not be used for detecting automatically and control, and precision is low.
The utility model purpose is to design the following novel load and weighing cell of small load of a kind of 500 grams, makes when measuring displacement minimum, the precision height, and corresponding electric signal output can be used for detecting automatically and control system in.
Scheme of the present utility model adopts to be made up of convoluted diaphragm and inductance type Linear displacement transducer, power is transmitted piece and diaphragm welds together, the iron core of the band adjuster bar power that installs to is transmitted on the piece, iron core is inserted among the coil that is fixed on the base, when measuring, masterpiece is used on the briquetting and is made iron core produce micro displacement by diaphragm and power transmission piece, the displacement that iron core produces in coil, the coil inductance value is changed, the output electric signal size of coil is directly proportional with the iron core displacement, promptly is directly proportional with the size of small load.
The utility model embodiment is further specified in conjunction with the accompanying drawings.
Fig. 1 is small load load and weighing cell structural representation.
By shown in Figure 1; the power transmission piece 4 that has overload protective function concurrently welds together with diaphragm 3; power is transmitted on the piece 4 pressure head 1 is housed; the threaded adjusting bar that power is transmitted piece 4 and iron core 5 partly links together, and holding screw 2 power that is loaded on that is used for tightening iron core 5 is transmitted in the piece 4, and iron core 5 inserts in the middle of the telefault 6 of band skeletons; protective sleeve 7 is equipped with in the coil outside; the displacement transducer coiler part is fixed on the base 9 by gib screw 8, and diaphragm is suppressed with mould by different range designs.
The utility model is a kind of novel sensor, the accurate measurement that has solved industrial small load, and displacement is minimum during measurement, the certainty of measurement height, and corresponding signal of telecommunication output is arranged, can be used for using widely industrial can the acquisition in automatically detection and the control system.
