Fisher 4200 Electronic Position Transmitter
The Fisher 4200 position transmitter senses the position of rotary or sliding-stem valves, vents, dampers, or other devices. When the instrument is mounted, a potentiometer shaft is mechanically connected to the device to sense mechanical motion. The instrument has standard or long-stroke capabilities for sliding-stem actuator applications. For long-stroke applications, a multi-turn potentiometer attached to a travel transducer assembly is used to sense linear motion of the actuator stem or other devices. This instrument with standard capabilities can also be used on quarter-turn actuators.
Features
1.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.
2.Electronic travel limit alarms have an adjustable deadband up to 10 percent of the maximum span.
3.The instrument, even with travel limit alarms, uses little space when mounted, allowing room for additional devices.
