The TopWorx 4310 wireless position monitor is a non−contacting wireless position switch. It is a rugged measurement device that provides a wireless on/off feedback signal to indicate equipment position. The 4310 can be used to monitor the on/off status of equipment such as valves, sliding−stem regulators, 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 on/off position of a measured device and transmits that data over the wireless network. The transmitted data includes two limit switch status indications, internal device temperature, 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 4310 wireless position monitor is powered primarily by a power module, eliminating the need to install wires. This makes it easier to design new applications or implement into retrofit locations. Additionally, the elimination of levers and linkages reduces the number of mounting parts and mounting complexity. Replacement and maintenance are simplified because the feedback parts stay with the measured device.

The 4310 wireless position monitor uses a high performance, patented (#7,005, 847) 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. WirelessHART_ communication protocol operating at 2.4GHz is utilized and is approved for use globally. Instrument calibration and commissioning is performed with a push button and liquid crystal display (LCD) interface. The interface is protected from the environment within a sealed enclosure. The interface supports multiple languages, including German, French, Italian, Spanish, Chinese, Czech, Japanese, English, Russian, Korean, and Arabic. Designed to meet intrinsically safe and non−incendive requirements, this instrument delivers scalable functionality in a small package. The power module option has no cable conduits. Due to the energy−limiting nature of the design, this intrinsically safe device is suitable for use in all zone locations. The 4310 provides two independent limit−switch equivalent feedback signals typically used with on/off applications.
