1. Reference accuracy can be affected as much as 5% per 50_C (122_F).
2. The pressure/temperature limits in this manual and any applicable standard or code limitation for valve should not be exceeded.
3. Due to the combustible nature of the lithium content, the power module has special installation, operation, storage, and/or shipping requirements. Observe all warnings included with the
power module before installing, operating, storing, or shipping. Contact your Emerson Process Management sales office if additional information is needed.
displacement and float level sensors, and relief
valves. It is designed to be simple to use, compact,
and easily mounted.
The wireless position monitor periodically reads the
position of a measured device and transmits that
data over a wireless network. The transmitted data
includes the percent of span value, two limit switch
status indications, and internal device temperature. It
also checks for instructions from host systems such
as distributed control systems (DCS), asset
management systems (AMS), and supervisory
control and data acquisition (SCADA) systems.

Terminology

Local Interface—All 4320 wireless position monitors
come standard with a Liquid Crystal Display (LCD)
and two (2) pushbuttons. The local interface
provides the capability to setup and calibrate the
monitor.
Magnet Assembly—This is the feedback component
that is mounted directly to the valve stem. It supplies
a magnetic field that is sensed by the wireless
position monitor.
