对于无交流电或交流电不正常而又要定时记录数据的场合,如测量地下水位、土壤温度、大气压力等,往往需要人工定时观测。本文介绍的记录仪配接传感器后,即可构成各种自动化测量系统,从而提高测量的可靠性、节省人力及经费。 For no AC or alternating current is not normal and time to record data occasions, such as the measurement of groundwater level, soil temperature, atmospheric pressure, often need to manually observe the time. This article describes the recorder with sensor, you can form a variety of automated measurement systems, thereby enhancing the reliability of measurement, saving manpower and funding.
