Fisher 4320 Wireless Position Monitor
Fisher 4320 Wireless Position Monitor from Emerson Process Management is a wireless position transmitter and limit switch. It can monitor any device that moves in rotary or linear fashion. The monitor periodically reads the position of measured devices and transmits that data over a wireless network. Instrument calibration and commissioning is performed with a push button and liquid crystal display (LCD) interface. The 4320 wireless position monitor is battery powered, eliminating the need to install wires. This makes it easier to design new applications or implement into retrofit locations. Emerson hails wireless technology as a “game changer” in the area of process control, noting that it lowers implementation costs, expands access to information, and expands the use of control systems into areas not considered before due to technical and economic barriers.
