Description
Technical field
The utility model relates to a kind of sensor-type Weighing module of composite protective, belongs to resistance strain weighing transducer field skill
Art field.
Background technology
In recent years, because electronic scale has, compact-sized, reading is directly perceived, speed of weighing is fast, precision is high, easy to carry etc. excellent
Put and be used widely.Its application field has penetrated into national economy and the every aspect of people's daily life, and China makees
For electronic scale big producer, the output of its electronic scale has accounted for global more than 70%, produce per year various commercial electronic weighing apparatus and
More than one hundred million of domestic electronic weighing apparatus.With the gradual extension and extension of electronic scale application field, there is one kind and be applied to aquatic products row
The waterproof electronic scale of industry and food production industry, to adapt to waterproof, protection against the tide and etch-proof handling characteristics.Its common practice is
The circuit part of electronic scale is encapsulated with box and glue, is isolated from the outside and reaches waterproof, etch-proof purpose.
At present, there are two kinds of ways for weighing sensor waterproof, anticorrosion：One kind is that weighing sensor is exposed, is only being passed
The surface smear anti-corrosion grease or coating of sensor；Second of way is to be encapsulated sensor with gum cover, make sensor with it is outer
Boundary's isolation reaches waterproof, corrosion-resistant purpose.Above two has following weak point for the way of the protection of sensor：For
A kind of way, although in the surface smear anti-corrosion grease or coating of sensor, due to corrosion be in molecular level, then
Plus chemical reaction and galvanic interaction so that its protection effect is less desirable；For second of way, due in sensor
On installed gum cover additional, although sensor is isolated from the outside, also have impact on the stress deformation of sensor so that scale it is aobvious
Show speed reduction, this is unacceptable for the operator by piece-rate wage.Simultaneously because the reinforcement effect of gum cover with
And internal gas pressure changes with the change of environment temperature, electronic scale is caused to be unable to reach weighing precision in small weighing,
It can not even use.It can not be used at all especially for this kind of means of defence of electronic scale of≤3kg ranges.
In addition, for the overload prevention of sensor, usual way is to install limit additional below the loading end of sensor
Position jackscrew.When load exceedes the specified range of sensor, spacing jackscrew will withstand the loading end of sensor so that sensing
Device does not continue to deform, so as to reach the purpose of overload protection.The weak point of this limit method is, when electronic scale is born partially
During load, due to the leverage of the arm of force, easily cause torsional deformation and damage, the manufacturer of present electronic scale is for sensor
Reverse limit do not account for without exception then.
