摘要
电磁力平衡式传感器是利用电磁力与负荷相平衡的原理工作,结构复杂但精度很高,常用于高精度电子天平。电磁力平衡式传感器由于材料和结构上的原因,线圈和磁钢之间的间隙很小。当人员操作不当或元器件损坏时,会产生各种故障。本文介绍了电磁力平衡式传感器和电子天平的工作原理,分析显示"ERR—54"故障代码的原因,讲述故障的修理过程以及修复后的校准。
Electromagnetic force-balance sensor functions on the principle of the balance between electromagnetic force and the load.Featuring complex structure and high precision,it is usually used on high-precision electronic balance.The gap between the coil and magnet steel is very narrow for the reason of the material and structure adopted by the electromagnetic force-balance sensor.It will run into many kinds of faults due to improper operation or component damage.This paper introduces the operating principle of electromagnetic force-balance sensor and electronic balance,analyzes the reason for having the error code "ERR—54" and demonstrates the repair process as well as how to calibrate the instruments after repair.
