应变式传感器生产过程中,重要的一个环节是传感器的补偿,包括零点补偿、温度补偿、弹性模量补偿、灵敏度参数调整等.国内传感器厂家主张0.03级、0.02级的传感器每只都要做温度补偿,包括灵敏度随温度变化的补偿.商业电子秤的敏感元——应变式传感器基本上都是5～60kg,准确度为0.03级、0.02级,必需做灵敏度随温度变化的补偿.电子秤用称重传感器全国需求量近亿只,如果采用单只传感器补偿装置,将严重影响生产率的提高.为满足传感器生产的需要,笔者研制了应变式传感器补偿装置,解决了生产中多只传感器补偿问题.应变式传感器补偿装置是综合试验装置,由高低温试验箱和静重式力发生装置组成,其技术指标是:
Strain sensor manufacturing process, an important part of the sensor compensation, including zero compensation, temperature compensation, elastic modulus compensation, sensitivity parameter adjustment, etc. Domestic sensor manufacturers claim 0.03, 0.02-level sensors each have to do the temperature Compensation, including the sensitivity of the compensation with temperature changes. Commercial electronic scales sensitive element - strain sensors are basically 5 ~ 60kg, accuracy of 0.03, 0.02, the sensitivity must be compensated for temperature changes. Weighing sensor national demand of nearly 100000000, if using a single sensor compensation device, will seriously affect the productivity improvement.To meet the needs of the sensor production, the author developed strain sensor compensation device, solves the production of more than just sensor compensation problem Strain sensor compensation device is a comprehensive test device, by the high and low temperature test chamber and static weight force device, the technical indicators are:
