YTMX580 System Configuration Example

YTMX580 Application Examples

  • Temperature monitoring is required to prevent wind-fueled fire hazards.
  • The measuring points are up to 600 meters away from the control room.

Install a YTMX580 on the side of the rotating furnace that can wirelessly transmit measured values from multiple temperature sensors.


Employ the ISA100.11a-compliant YTMX580 Multipoint Wireless Transmitter. The YTMX580 has 8 channels of universal input, which is perfect for multipoint measurement applications, and it can withstand harsh operating temperatures of -40 to 85 °C.


A battery room is used to storage batteries for emergency power management in the plant. Each substation has battery room and the storage batteries are lead-acid batteries which must be maintained within specified operating temperature limits. Temperature management is important to ensure a long service life of the batteries especially for the plant in desert climates.


Delayed Coker is a type of coker who's process consists of heating residual oil feed to its thermal cracking temperature in a furnace. The most important variable in industrial furnace control is temperature. Temperature is measured throughout the furnace in different zones and temperature effects the materials being manufactured and therefore must be precisely monitored to prevent deviations in quality of the final product.


An induction furnace melts metal by creating very large currents in the material. These currents are induced using three electrodes positioned inside the furnace. The furnace is automated so that once the material has been melted, the electrodes are removed and the furnace then tips the molten metal into a crucible where it can be easily transferred to the production line where it will be cast into ingots. The atmosphere is extremely aggressive and the wired infrastructure is both expensive and very unreliable to maintain. The furnace control requires a total of 20 measurement points distributed around and inside the furnace. The harmonic field effects caused by short circuit 40,000 A (300V). The causes significant interference.


Customer needed efficiency improvement of steel manufacturing by temperature monitoring for heat/cooling equipment. Previous system required periodic compensation lead changing.


The client wanted to monitor the temperature on a chimney. Exhaust air is exposed to the heat on the way traveling from the inlet to the outlet in the chimney. Then constituent of the air transform to harmless elements. It is important to keep the temperature in the chimney as designed.


Direct Reduction Iron (DRI) is one of the processes to reduce oxygen from iron oxide pellets for steel plant. More than 90% of DRI processes use heated LNG as process gas where PID control for temperature or interlock control is of vital importance.


One important risk to manage with regard to coal stacks is preventing fires due to spontaneous combustion.


Temperature control of exhaust gasses coming off various combustion processes in refineries and related facilities is often critical to effective pollution abatement and compliance with applicable regulations. There are specific temperature windows where toxic gasses can form or other substances can condense, causing corrosion and other harmful effects, so operators need to make sure the process is running at the correct levels.

Stacks, chimneys and other gas handling equipment can take all sorts of forms depending on the application. Some may include scrubbers, gas cooling, chemical injection, afterburners or ambient air mixing—but a common element is the need for effective temperature measurement of the gas at various points in chimneys (Figure 1).

Given the length and height of a chimney, its associated ductwork and ancillary systems—there can be dozens of sensors inserted at strategic points from one end to the other—providing the process automation system and the plant operators with critical temperature data. These sensors are often in hard-to-reach locations where installation and maintenance are difficult. While these sensors are often spread over a great distance, they must connect back to one central point where the larger gas treatment system is controlled.

Figure 1. Chimneys found in refineries and other hydrocarbon processing facilities often require temperature monitoring.

Monitoring a Refinery Main Chimney

At a refinery in the Americas, the main chimney is located 300 m away from the main control room, and there are about 30 temperature sensors mounted on the structure, the highest of which are 30 m above the ground. Wiring for such an installation was going to very challenging, so the company instead installed an ISA100 wireless network.

When the refinery was designing the system initially, it was clear the cost of individual wireless transmitters for each temperature sensor would be expensive and take too long to install. To alleviate these issues, the refinery selected Yokogawa YTMX580 Multi-Input Temperature Transmitters, each of which can accept up to eight individual sensors and send the data back via a single wireless transmitter (Figure 2). Each unit can accommodate a variety of RTD and thermocouple types to meet application demands.

This approach minimizes the amount of required wiring while also cutting the cost of the wireless infrastructure. Four of these multi-input transmitters are installed at the facility to service the group of temperature sensors, eliminating the need to add cabling to the control room. The plant’s wireless network backhaul infrastructure brings data from the chimney to the operators so they can monitor system performance in real time.

The success of this installation has given the plant the confidence to extend the ISA100 wireless network using Yokogawa’s Plantwide Field Wireless infrastructure.

Figure 2. Wiring temperature sensors installed in a chimney back to a control room can be challenging and expensive, so many plants and facilities are instead implementing wireless solutions, such as this Yokogawa YTMX580 8-input temperature transmitter.



Since 2010, Yokogawa has been providing wireless products conforming to the ISA100.11a wireless communication standard for industrial automation (IA). As a new addition to the lineup, Yokogawa has developed the YTMX580 multi-input temperature transmitter. Like the YTA510 temperature transmitter, YTMX580 is driven by batteries, but the number of its inputs has been increased from two to eight.
