产品简介

产品描述: 精量电子－－MEAS传感器在汽车安全测试方面拥有数十年的经验。FN4055专为座椅安全带力的精确测量而设计，由于产品对于来自测试假人的接触应力并不敏感，测量结果精准反映安全带的实际拉力。FN4055量程小，因而特别适合儿童座椅安全带的测试。传感器内置机械过载保护，防止过载。请参阅EL20-S458规格书，了解相同用途的大量程传感器。作为拥有多年经验的传感器设计和制造商，MEAS常常与客户合作，按要求定制适合特殊用途和测试环境的传感器。

特点:

• 内置机械过载保护，防止过载
• 使用时无需割开安全带
• 高精度
• 250N量程
• • Measurement Specialties has applied our decade of experience serving the automotive crash test
  • industry to design the ultimate crash test seat belt restraint sensor.
  • Created for the automobile industry, the FN 4055 measures with excellent accuracy the forces exerted
  • on the seat belt. Only the actual compression upon the seat belt is measured, as the sensor is insensitive to
  • contact from the crash test dummy. The unit is designed for very low range, like tests for kids security. It is
  • protected against overload by mechanical stops.
  • For a new example of similar application with higher range, please read the datasheet of EL20-S458.
