Description :

200t force sensor, 0.3 level precision standard force gauge, 2000kN column weighing sensorDetailed description: Various force sensors of Youzhongli can be divided into button type, tension pressure type, column type, spoke type, etc. according to their structure, and various structures meet the needs of different installation scenarios. Instruments can be selected according to on-site requirements, including economical instruments, control instruments, handheld instruments, standard instruments, etc.

　　Column type sensor

　　During the measurement process, gravity acts on the elastic body, causing deformation. This strain (positive or negative) is converted into an electronic signal by strain gauges attached to the elastic body. In addition to the essential strain gauges and elastomers, sensors usually also include a protective shell for the strain gauges, sealing elements, etc.

　　Hollow column sensor

　　The upper part of the elastic body is welded to the protective shell through two films. They are very rigid in the horizontal direction to prevent damage from lateral forces, and the measurement direction is flexible so that no horizontal force is generated during the measurement process. The circuit wiring is also led out from the protective ring through an airtight glass conduit. Especially forming a sensor with a completely sealed packaging. Its strain gauges are not affected by external gases and liquids.

　　For sensors measuring extremely high loads, another shape of elastic body is usually selected, such as hollow cylindrical or tubular, while square columns are not suitable because a uniform strain field that is conducive to strain gauge measurement cannot be obtained. The picture shows a hollow cylindrical elastic body, which is relatively easy to manufacture and has extremely high resistance to lateral forces. And sealing is also easy to achieve, but the adhesion of strain gauges is relatively difficult.

　　Fan shaped hollow cylindrical elastomer

　　Hollow cylindrical elastomers have load loading problems and relatively high hysteresis errors, so the shape shown in the figure is often used in practice. The hollow column is divided into multiple sectors to reduce hysteresis, and the load is introduced through a fixed plate.
