4320

The Fisher 4320 wireless position monitor eliminates the need for wiring to an on/off, pneumatically actuated valve. It provides a precise wireless feedback signal to indicate equipment position with a percent of span plus on/off indication. The 4320 can be used to control and/or monitor valves, sliding-stem regulators, displacement and float level sensors, and relief valves. It is designed to be simple to use, compact, and easily mounted.

Features

  • The linkage-less feedback system is easy to install with a magnet array assembled to the valve stem.
  • With the pneumatic output option, only air is needed to automate an on/off valve.
  • The optional pneumatic output has ultra-low steady state air consumption. Air generation costs can be reduced.
  • The WirelessHART™ self-organizing mesh network provides the high level of communication reliability required in process control.
  • More than 5 years of operation is typical, using standard life and extended life power modules. Optional ability to use local 1228 V power in the field.
  • The feedback design provides more accurate monitoring and eliminates physical wear-out, common in traditional valve instruments.
  • Predefined device, network, and system diagnostics provide details on the health of the device and its ability to communicate.
