Usage & Applications:
HAIBOSENSOR BF350-3BB strain gauge, with precise resistance accuracy, low temperature drift, and high mechanical stability, is the core sensitive component of various small/miniature weighing and pressure sensor modules. It focuses on three core fields of weighing sensing, industrial force measurement, and precision detection, with precise application scenarios as follows:
Fabrication of weighing sensors: The core sensitive component of single-point load cells, parallel beam load cells, and miniature load cells, suitable for the R & D and production of civil/commercial small weighing equipment such as electronic scales, kitchen scales, courier scales, and small bench scales;
Industrial small force measurement: Fabrication of miniature pressure sensors and miniature tension-compression sensors, applied to industrial precision force measurement scenarios such as small force measurement in automated production lines, pressure detection in light industrial packaging equipment, and micro tension measurement in textile machinery;
Precision sensing of instruments and meters: The built-in sensing core of various portable testing instruments and miniature force measurement instruments, suitable for small force value detection in laboratories and precise collection of micro-deformation/micro-force values in industrial sites.
