Temperature Monitoring by Wireless Communication at Furnace

Introduction

Electrical Furnaces used at steel mills to heat and melt metals, require a water cooling system to provide consistent and safe heating. If part of the cooling system fails, it can affect the quality of the product and also risk the safety of the facility and the operators.
For steady control, hundreds of temperature sensors can be installed around the furnace. However the sensor wiring is often damaged by the heating environment. The application also generates strong electrical noise which leads to erratic measurements making it difficult to apply proper control.

Proposal

To overcome the challenges associated with severe ambient condition or the presence of strong electrical noise, Yokogawa recommends a Field Wireless solution based on ISA100 Wireless technology.

  • Compared with wired data transition with long signal wires, the wireless data transmission is not susceptible to electrical noise.
  • Switching to wireless measurement reduces the labor and cost associated with ongoing replacement of wires near the harsh furnace environment.
  • Yokogawa’s Field Wireless solution provides better data quality for temperature control, reduced maintenance cost and improved product quality as a result of stable temperature control.

Features of YOKOGAWA Field Wireless

  • YTMX580 is the multi-input temperature transmitter. One unit can support up to eight temperature sensors.
  • The data from YTMX580 can be transmitted up 500 meters line of site. Even in dense process piping without direct visibility to the next router, reliable communication of 50 meters can be achieved. These are the benefits of ISA100.11a protocol.
  • It is scalable up to 500 wireless units (including routers).
  • Coexistence with Wi-Fi: Robust, reliable communication

Wireless : Steady, Max. 500m / Wired : subject to noise issues
