Электронный датчик положения Fisher™ 4200

A precision film-element potentiometer in the standard unit and a precision multi-turn wirewound potentiometer in the long-stroke unit provide exceptional linearity by matching the span of the sense element to the application.;To eliminate the need for externally mounted mechanical limit switches, instruments with travel limit alarms incorporate comparator circuits that monitor the sense potentiometer voltage output.;Electronic travel limit alarms have an adjustable deadband up to 10 percent of the maximum span.;The instrument, even with travel limit alarms, uses little space when mounted, allowing room for additional devices.;A simple hybrid electronic design combines the best qualities of discrete components and integrated circuits for improved reliability and performance.;The field wiring compartment is isolated from the electronic compartment. This protects the electronic circuits from any moisture brought into the housing via the field wiring ports.
