烟熏记录地震仪的技术改造——ARA放大器的应用之二

TECHNICAL TRANSFORMATION ABOUT THE SEISMOGRAPH OF SMOKED PAPER RECORDING---The Second Application of ARA Amplifier

对六十年代生产的烟熏记录地震仪进行技术改造:保留烟熏记录,保留65摆(或DD—1摆)以ARA积分放大器代替线性放大器,以线性笔头代替积分记录笔,增配电子报警器及交直流自动切换电源,组成新的地震观测仪器系统。技术改造方案在广东地震台网实施、两年来仪器运行正常、效果很好。

We have transformed the seismograph of smoked paper recording made in the sixties. The smoked paper recording and pendulum of DD-1 are retained in this transformation. The linear amplifier is replaced by integral amplifier of ARA and integral recording pen by linear pen.Ele-ctric alarm and automatic cutting power supply of alternating and direct are allocated to compose the new system of seismic observating instrument. After applicated in the seismic stations of Guangdong Province, this instrument moves in good order and good results are achieved.
