Description
Technical field
The invention belongs to sensor technical field, it is related to a kind of load-type sensor, specifically a kind of extension of plate ring structure
Ring sensor.
Background technology
Existing hanging ring type sensor, is mainly used in the fields such as electric power and building, its typically using plate ring structure and
Pole structure.The hanging ring type sensor of existing plate ring structure and pole structure, generally portion sets one to answer in the sensor
Become area, the conduction of stress has some setbacks, and the reason for it is because of strain structure itself has conflict in some field installation dimensions, meanwhile,
Power industry, old-fashioned link pulling force precision very poor can only have 1% or so, and transducer range is difficult to do small.
The content of the invention
It is an object of the invention to provide a kind of high plate ring structure link sensor of easy to install, measurement accuracy.
The purpose of the present invention can be achieved through the following technical solutions：
On a kind of link sensor of plate ring structure, including sensor body, the upper and lower both sides side wall of sensor body
Two opposite screws of hand of spiral are had, two screws connect suspension ring or suspension hook by screw mandrel respectively；
Provided with two relative circular strain grooves in the middle part of the sensor body, foil gauge is posted in the strain groove；
Bar-shaped trough is provided between two relative strain grooves, the screw is mutually communicated with bar-shaped trough.
Further, the strain groove upper and lower both sides are respectively equipped with the first opening and the second opening, first opening and
Second openings are in opposite direction, in strain groove the week side of boss formation S types force area.
Beneficial effects of the present invention：The link sensor for the plate ring structure that the present invention is provided, changes existing hanging ring type and passes
The structure of sensor, strain regions therefrom between be changed into both sides, solve occupancy of the strain regions to installing space, can be selected when using
Foil gauge resistance change in any strain groove of measurement, calculates the pulling force size that sensor is subject to, or measures two simultaneously
The foil gauge resistance change in groove is strained, synthesis draws the pulling force size that sensor is subject to, solve existing hanging ring type sensing
Portion sets a strain regions to device in the sensor, causes the problem of conduction of stress has some setbacks, greatly improves the precision of sensor, can
Make small-range sensor.
Brief description of the drawings
