INPUT POTENTIOMETER [6 records]

Record 1 2003-05-01

English

Subject field(s)
  • Systems Analysis (Information Processing)
DEF

A device used in analog computers for representing a function of one variable, consisting of a potentiometer with a number of taps held at voltages determined by a table of values of the variable; the input variable sets the angular position of a shaft that moves a slide contact, and the output voltage is taken from the slide contact.

Record 4 1977-11-07

English

Subject field(s)
  • Geological Research and Exploration
  • Geophysics
OBS

Since the currents cannot be measured directly, it is necessary to measure the potential gradients between electrodes planted on surface or possibly in drill holes(...) non-polarizing electrodes should be used to reduce erratic potentials at the soil contact; lead plates, which are fairly inert chemically, are often employed instead. The electrodes are connected to an amplifier which will drive a strip chart or magnetic tape recorder. If specific frequencies are of interest, various bandpass and reject filters are incorporated in the amplifier section. Also, static potentials between the electrodes, which may be several hundred millivolts, must be balanced out; this is done with a potentiometer, or capacitance input, the latter having a time constant considerably longer than the maximum period to be recorded.
