the device at the entrance of system or instrument, which
converts input actions into the signals, convenient for further the
processing, transfer and registration or for the agreement of the work
of systems with different input - output parameters. Depending
on the phys. of nature of signal, form of its idea, operating
principle of source and sensing transducer there are v. p. of
neelektrich. of values (for example, pressure, displacement,
temperature so forth.) in the electrical (current, stress,
charge) and vice versa; elektrich. and neelektrich. of
values into the code (for example, digital, position and other.)
and vice versa (see also sensor, measuring
converter, conversion of the idea of value). Osn
requirement for v. p.: the maximum accuracy of the transfer of
input action and minimum influence on the work of the soglasuyemykh
systems or devices. M. m. gel'man.
