Wireless Adapter

1. Overview

The wireless adapter is designed to have remote access to any 4~20mA HART meters via wireless WIA network. By increasing the remote access ability for HART meters, other process variables of HART meters can be monitored, thus resolving the system design problem of HART instrument grounding without paving monitoring cables to the control room. It can also be applied to asset management in factories.

Wireless adapter design mainly includes loop power supply, wireless transmission, remote operation and maintenance, local operation and maintenance. 

    2. Features

      Making wired HART instruments have the ability of wireless communication, such as pressure, temperature, liquid level, flow and valve, becoming a new measurement point of wireless network.

      In case of factory expansion or additional process monitoring point implementation, it is difficult to pave long communication cables, and the cost is high, so local power supply can be utilized to installed the traditional wired HART instrument for connection;

      Senior diagnosis by intelligent instruments can be realized. Via the management system, senior diagnosis, online proving and unit check for intelligent instruments can be realized.

      Monitoring to the state of intelligent meters is increased. In case of failures, the failure warning of equipment will be checked; In case of equipment replacement, the equipment configuration will be conducted to reduce the time needed for troubleshooting.
