Description
Technical field
The present invention relates to weighing technology, more particularly to a kind of weighing sensor.
Background technology
What weighing-appliance was generally said is the weight weighing utensil of the large-sized object for industry or trade, and weighing-appliance is main
By load bearing system (such as scale pan, scale body), power transmission converting system (such as lever transmission system, sensor) and indicating value system (such as scale
Disk, electronic display meter) 3 parts composition.Weighed now in producing and selling are combined, weighing-appliance is received greatly
Concern, the demand of its weighing-appliance is also increasing.
Using the electronic weighing appliance of Modern Sensor Technology, electronic technology and computer technology integration, it can meet simultaneously
" quickly, accurate, continuous, automatic " for solving to propose in actual life weighs requirement, can effectively eliminate human error, be allowed to more
Meet the application requirement that legality measurement management and industrial processes are controlled.
Traditional tank weights are all measured by radar, ultrasonic technology, but radar, ultrasonic wave etc. are present
Inaccurate intrinsic problem is measured for what solid material uneven surface, dust etc. were caused, therefore weighing level indicator is in the modern times
It is widely used in the thing position observing and controlling of metallurgy industry, progressively instead of radar and ultrasonic material level detection unit.Weighing type material position
Meter is used cooperatively with four sensors again based on, but this structure there is also it is larger the problem of, for heavy weight storage tank, it is single only
Weighing sensor price is all costly, if complete also can band with the increase virtually added in input cost, number of sensors
The unstability of incoming telephone signal.
Chinese patent application 201310396499.8 discloses a kind of hinge type storage tank Weighing device, including vertical storage
Tank 1, supporting leg 2, base 5, weighing sensor 3, hinge 4, terminal box, weight transmitter, PLC and computer, it is characterised in that
