The overweight sensor and the overload protective device of this measuring apparatus, they are fixed on outside the normal hunting range of measuring mechanism to be fixedly coupled mode, and keep specific distance with measuring mechanism.The size of specific range is to determine like this: this is apart from guaranteeing that measuring mechanism can not touch two mechanisms when measuring normal swing.Tilt just to have exceeded normal range when the swing of measuring mechanism, at this moment specific range guarantees that just in time measuring mechanism contacts with overweight sensor, and overweight sensor measurement goes out measuring mechanism to its power that applies, and slows down the swing inclination of measuring mechanism.When the unbalance loading amount of measuring mechanism during greater than the measurement range of overweight sensor; the swing of measuring mechanism is tilted bigger; at this moment overload protective device guarantees just in time that with specific range between the measuring mechanism overload protective device contacts with measuring mechanism, and the further inclination of restriction measuring mechanism.Reach the purpose of the unbalance loading value of prompting measuring system heap(ed) capacity, and the undue inclination that has limited measuring system has prevented that unbalance loading from damaging whole measuring system.
Two carrying vessel of this measuring apparatus and mechanics standard counterweight hang on the measuring mechanism simultaneously, can load measured and standard volume to measuring system by them.During measurement, material in carrying vessel is motionless as counterweight, by another vessel measuring system is carried out the complete method of substitution comparison of measured and standard volume earlier, material in these vessel of comparing is motionless as counterweight afterwards, by as the vessel of counterweight measuring system being carried out the complete method of substitution comparison of a measured in addition and standard volume just now.Just can reach under the lower load-bearing capacity of measuring system, the purpose that doubles the maximum measurement capability of direct method weighing is provided.
Measuring mechanism and the mechanism that two kinds of needs of supporting mechanism that measuring mechanism is played a supporting role are moved, measuring mechanism is placed on the supporting mechanism, these two kinds of motion of mechanism are by the realization that is used for of lifting mechanism, supporting mechanism is connected in a fixed manner with lifting mechanism, and has guiding mechanism, with motion and fixed mechanism, link to each other in a fixed manner respectively, play effect motion location and guiding.When device was measured, measuring mechanism can be that axle is swung with the fulcrum.When measuring apparatus loads measured or standard volume, need the carrying vessel, measuring process is that measured value and standard volume value are compared.The weighing technique of rolling friction guiding mechanism, overweight prompting overload protecting mechanism and the complete method of substitution weighing of two carrying vessel.
Advantage of the present invention is, good repeatability arranged, can provide the concrete value of unbalance loading during greater than the automatic measurement range of device and improve the maximum capacity scope of measuring apparatus under identical manufacturing cost in the unbalance loading of heap(ed) capacity.
