Fisher® 4320 Wireless Position Monitor - 1

Product Bulletin Fisherr 4320 Wireless Position Monitor 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, slidingstem regulators, displacement and float level sensors, and relief valves. It is designed to be simple to use, compact, and easily mounted. The control portion of the 4320 accepts commands through the wireless network from a control system and provides a pneumatic on/off signal to an actuator. The feedback portion of the instrument periodically reads the position of a measured device and transmits that data over the wireless network. Transmitted data includes the percent of span value, limit switch status indications, valve set point, internal device temperatures, and power module voltage. It also checks for service and configuration instructions from host systems such as distributed control systems (DCS), asset management systems (AMS), and supervisory control and data acquisition (SCADA) systems. The 4320 can be powered by a battery sourced power module, eliminating the need to install wires. This makes it easier to design new applications or implement into retrofit locations. An external power option is also available. The elimination of levers and linkages reduces the number of mounting parts and installation complexity. The autocalibration feature allows consistent valve feedback. The 4320 uses a linkage-less feedback design that eliminates direct contact with the measured device (e.g., valve, regulator, level, louver, or other devices) eliminating physical contact and wear. IEC 62591/ WirelessHARTr communication protocol, operating at 2.4 Ghz, is utilized and is approved for use globally. ON/OFF CONTROL OPTION Instrument calibration and commissioning is performed with a push button and liquid crystal display (LCD) interface. This simplicity eliminates the need for tools or the setting of cams during setup, saving you time. Designed to meet intrinsically safe and nonincendive requirements, this instrument delivers scalable functionality in a small package. Due to the energylimiting nature of the design, this intrinsically safe device is suitable for use in all zone locations. The battery sourced power module option has no cable conduits.

Fisher® 4320 Wireless Position Monitor - 5

Product Bulletin Features n Simplicity— The 4320 is easy to use. The linkageless feedback system is easy to install with a magnet array assembled to the valve stem. The 4320 has a local user interface that will allow you to calibrate the instrument. The full text display in the local interface is easy to navigate, in part due to the selection of languages. n Quick Installation—Simply attach the 4320, calibrate and commission to any control system. With the pneumatic output option, only air is needed to automate an on/off valve. No conduit easements or permits are required with the standard...

Fisher® 4320 Wireless Position Monitor - 6

Product Bulletin 62.3:4320 July 2014 Integration Because the 4320 wireless position monitor operates with WirelessHART communications it can be used for incremental monitoring applications. This replaces manual efforts to audit or verify equipment position during normal operations, such as startup and shutdown situations, product changeover, product isolation, and sampling activities. One implementation method can be accomplished using an overlay approach; adding wireless instrumentation on top of existing instrumentation. This preserves the existing infrastructure and enables improved...

Fisher® 4320 Wireless Position Monitor - 7

Product Bulletin Ordering Information When ordering, specify: 1. Position monitor control For linear movement, indicate travel length: n 7 mm (1/4 inch), n 19 mm (3/4 inch), n 25 mm (1 inch), n 38 mm (1-1/2 inch), n On/off control option 2. Power source n Battery sourced power module n External power option 3. Mounting requirements Feedback sensor and mounting brackets are part of the mounting. Note As a general rule, do not use less than 50% of the magnet assembly for full travel measurement. Performance will decrease as the assembly is increasingly subranged.
