| Abstract: | 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. |

| Keywords: | [pressure sensor] zero drift [automatic correction] [S/Hcircuit] |
