ITEM NAME:10pcs BF350-3AA BF350 350 ohm High-Precision Pressure Resistance Strain MMC Descriptio n Specifications: Material: metal Color: picture color Size: length :7mm* width :5mm Weight: 50 g Product list: 10* resistive strain gauge Specification of strain gauge: Model no. : bf350-3aa (**) N* Grid wire: long x wide 3.2x3.1mm Base size: l x x 7.4x4.4mm Base material: modified phenolic base. Resistance: 350 ohms Use method of strain gauge: (1) mainly applicable to the manufacturing process of pressure sensor of level 0.02. The 0.02 level means that the output error at full scale is within the range of plus or minus 0.02. Very accurate. I will describe the specific sensor manufacturing process in detail later. (2) directly measure the strain of the component. The strain gauge is pasted directly on the deformation part of the component. When the component deforms, the resistance value of the strain gauge changes. The resistance change of the strain gauge can be measured through the resistance strain measuring device (strain gauge) and converted into the electrical signal (voltage, current) that is proportional to strain or strain. (3) circuit selection (very critical in red) The resistance strain gauge change is very small, must have the appropriate circuit to detect the small changes, we usually choose a circuit, the circuit of the change of the resistance strain gauge to control circuit, the circuit can output similar to the resistance changes of electrical signals (voltage or current), then the proper handling of the signal can be (enlarge) processing. Package Included: 10pcs Pressure Resistance Strain Gauge Honesty is gold for all! 10pcs BF350-3AA BF350 350 ohm High-Precision Pressure Resistance Strain Gauge
