压力传感器零位温漂的自动校正——介绍一种“永久性”的S/H电路

AUTOMATIC CORRECTION TO THE THERMAL AFFECTED ZERO DRIFT THE PRESSUER SENSOR--A "PERMANENT" S/H CIRCUIT

介绍了一种新颖的采样保持S/H电路。它具有定点采样,永久保持信号的功能。在铁路原油装车安全系统中。它被用来自动测量压力传感器的零位漂移量,并送往调整电路进行自动校正,取得了令人满意的效果。

We described a new style of sample holding circuit, which samples at fixed position and holds signals permanently. In the security system for the crude oil loading and transportation, the circuit has been used, to our satisfaction, to collect data, to measure the zero drift of the pressure sensor automatically and to correct it by a correcting cir- cuit.
