Problems solved by technology

It solves the problem that no matter what kind of structure the load cell of the existing static or dynamic rail scale adopts, due to the limitation of the elastic deformation area and the high accuracy requirements of the rail scale for the measurement sensor, it is impossible to simultaneously output two loads for the same load on the rail scale sensor. The limitation of the function of measuring the value of the vertical force of the road, thereby improving the status quo that the static track scale and the dynamic track scale cannot be combined into one

Embodiment Construction

[0018] In the sensor device of the present invention, the resistance strain gauges required by the 2-way Wheatstone bridge circuit are arranged in a specific configuration on the bottom surface of the shear strain blind hole web of the same beam or plate sensor elastic body. Each way alone forms a Wheatstone bridge circuit.

[0019] Such as figure 1 As shown, eight strain gauges with the same resistance value in the first route R1~R8 form a Wheatstone bridge circuit, in which R1~R4 are sheared pullers, R5~R8 are sheared pressure pieces; 2 are used for The temperature zero point compensation resistors Rt1 and Rt2 are respectively connected in series to the adjacent bridge arms, and the two no-load zero point compensation resistors Ro1 and Ro2 are also connected in series to the adjacent bridge arms respectively, and the positive electrodes of the power supply bridge are respectively connected in series to the elastic The modulus compensation resistor Rp1 and the gage coefficie...

Abstract

The invention provides a double-perpendicular force integrated digital transducer which arranges of strain gauges of two groups of bridge circuits with same constitutions on a shearing strain blind hole web bottom of a same girder type or a plate type sensor elastic body in a certain configuration mode. The double-perpendicular force integrated digital transducer realizes high accuracy output of the double-path perpendicular force output signals under the same load.

Description

technical field [0001] The invention relates to the field of electronic digital sensors, in particular to a resistance strain digital sensor with double vertical force output. Background technique [0002] Rail scales are equipment installed on railways to measure the weight of goods loaded on trains. Rail scales are usually composed of auxiliary equipment such as load-bearing platforms, sensors, weighing displays, and digital printers. They can automatically display weighing values, and have the characteristics of remote transmission of information and continuous measurement. Due to these characteristics, rail scale technology has been widely used in factories, mines, metallurgy, foreign trade and railway departments to weigh truck bulk goods. [0003] Existing track scales are usually divided into two categories: static track scales and dynamic track scales. The construction of a conventional dynamic track scale requires at least 250 square meters of land to be concreted,...
