Description
Technical field
The present invention relates to vibrating wire sensor technical field, be specifically related to the aluminium base elastomer metal material of girder steel and compensate sensor.
Background technology:
Existing vibratory string compensates sensor when elevator weighing, can because the difference of thermal expansion value produces error, impact operation.
At present, vibratory string on the market compensates sensor and there is the problem that resolution is low, elastic hysteresis is general, and general girder steel adopts Q235 material, and it is aluminum alloy material that vibratory string compensates sensor, and Q235 is different from the thermal expansion value of aluminium alloy, there will be the problems referred to above in operation.
It is integral molding with sensor itself that existing vibratory string compensates the connector of sensor both sides, so entirety is all same thermal expansion value, there is very big difference with the girder steel of general material.
Summary of the invention
For the problems referred to above, the girder steel that the technical problem to be solved in the present invention is to provide a kind of reasonable in design, easy to operate, resolution is high and elastic hysteresis is good compensates sensor with aluminium base elastomer metal material.
The girder steel of the present invention compensates sensor with aluminium base elastomer metal material, and it comprises shell, circuit board, support, magnet, vibration string, elastic component, connector; Connected by support between described shell, circuit board; The centre of described outer casing inner wall is provided with magnet; Described magnet be symmetrically arranged on two with vibration string; Described vibration string is connected with elastic component; The bottom of described elastic component is interted in the circuit board; The two ends of described shell are connected with connector by screw.
As preferably, the summation of the thermal expansion value of described shell and connector is equal to the thermal expansion value of girder steel.
As preferably, the two ends of described shell are arranged with two and stablize boss, are used for improving the stability of whole sensor.
Shell in the present invention and connector adopt split-type design, so can with general girder steel material heat of neutralization swell value, thus improving the stability of operation.
Beneficial effects of the present invention: its reasonable in design, easy to operate, motility is good, and stability is high, it is possible to improve the accuracy of detection object stress, it is to avoid problems of the prior art, applied widely.
