Strain Gauge or Strain Gage was invented in 1938 by Edward E. Simmons and Arthur C. Ruge. The force is applied to one side of a diaphragm of flexible material and balanced by pneumatic pressure on the other side. With the multi-point type, three or four load cells are generally used to make a scale. A pneumatic load cell is shown schematically in Figure 18.3. Unlike load cells that measure along the vertical axis, they are not forced to sense the roll weight along with the web tension. TH4 load cells are perfectly suited for use with any type of tank, batching or platform scales as well as for level monitoring - and are used by market leaders. They offer high accuracy and repeatability as well as long life. Slideshare uses cookies to improve functionality and performance, and to provide you with relevant advertising. (3) S type (4) Washer type Pneumatic load cells function similarly to their hydraulic counterparts in that they convert fluid pressure into a load measurement. A load cell is nothing but a transducer which is used to create an electrical signal. To efficiently detect the strain, strain gauges are bonded to the position on the spring material where the strain will be the largest. Part Number: 28-001869 LOAD CELL. To efficiently detect the strain, strain gauges are bonded to the position on the spring material where the strain will be the largest.
