A
preamplifier is required to amplify the output of an Inductosyn® transducer before the
output is sent to a converter. The linear cassette and spar type transducers can be
supplied with preamplifiers installed. For other linear or rotary transducers,
separate preamplifiers must be used. Farrand can supply preamplifier model 219200
with screw terminals or preamplifier model 218891 or 219594 with solder terminals.
Wide temperature range versions of the solder terminal types of preamplifiers are
available. Farrand can also supply preamplifiers installed in boxes for direct
mounting to machines. For the most demanding applications, hybrid preamplifiers are
available. MIL-spec, class B, and class S models can be supplied.
