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.
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.
