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.
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.
YFGW520 (Field Wireless Access Point)
YFGW410 (Field Wireless Management Station)
YTMX580 Multi-Input Temperature Transmitter
Reliability of the wireless system is ensured by redundant wireless channels and devices. Redundancy achieves high-speed switching.
Yokogawa Full Redundant System
With a variety of security functions including device authentication, message authentication, message freshness checks, and encryption, the field wireless network is protected from multiple types of cyber attacks.
A breakthrough method to increase reliable and optimize networks with 2.4GHz wireless communication, being suitable for plants and other locations. It supports long distance communication in trunk communication path, covering lots of IO with less routing devices, resulting to economical wireless network topologies.
Replaceable in hazardous area, max 10-year battery life depending on operating condition.
Battery pack, certified with explosion proof
YFGW410 Field Wireless Management Station has system manager/security manager/gateway function based on ISA100.11a, and combining this with Field Wireless Access Point(YFGW510) and/or Field Wireless Media Converter(YFGW610) composes the field wireless system.
YFGW510/YFGW520 Field Wireless Access Poin has backbone router function based on ISA, and combining this with Field Wireless Management Station (YFGW410) and/or Field Wireless Media Converter (YFGW610) composes the field wireless system.
YTMX580 can accept inputs from up to 8 points of measurement such as thermocouples (8 types: K, E, J, etc.) or RTD signals (3 types: Pt100, etc.), converting the corresponding measurement input values to a wireless signal. It can also accept DC voltage, resistance, and 4 to 20 mA DC signal input.
The flexibility of wireless solutions enables less investment in infrastructure while providing greater insights into plant operations.
Yokogawa offers an IoT Enabled ISA100 compliant Gateway, a Access Point, a Media Converter, and a Management Station. All to help design a network to meet your needs.
Yokogawa offers the dual-input YTA510 and the multi-point YMTX580 temperature transmitters.
