Yokogawa Adds Network Function to its UTAdvanced Series Digital Indicator

Yokogawa Electric Corporation announced that it has added a network function to the UM33A digital indicator with alarms, a product in the UTAdvanced controller series, and will release this to the market on May 7. With this network function, a single UM33A digital indicator can receive, process, and sequentially display data from up to eight sensors. The enhanced UM33A is an easy to install and cost effective solution that enables the monitoring of data from multiple field sensors.

The UTAdvanced series controllers are mounted on furnaces and other types of heat process-related industrial facilities for the measurement, display, and control of operating variables such as temperature, pressure, and flow rate. The UTAdvanced controller comes standard with a sequence control function based on the ladder logic programming language, which is widely used by engineers. Improved design efficiency and elimination of the need for relays and other peripherals have resulted in a lower price.

Features of the Enhanced Digital Indicator Model

1. Easy to introduce/improved monitoring of data

The enhanced UM33A supports the master function and the data monitoring function of the Modbus/RTU communication protocol, and is able to connect with up to eight sensors and sequentially display data from those devices. The UM33A is thus able to monitor data from multiple field sensors without requiring the installation and engineering of a separate device with user interface and controller functionality. It can also function alongside already installed systems that employ such specially configured hardware. With its ability to remotely connect with multiple sensors throughout a site, the enhanced UM33A makes it easier for plant personnel to check measurement data from these devices.

2. An enhanced field digital solution

In plants, progress is being made in the introduction of field digital solutions that rely on digital communications between intelligent field devices and control systems. Field digital solutions allow the transmission of significantly greater amounts of data, including not only data on process parameters but also instrument status information, and the ability to monitor this information online improves maintenance efficiency. Thanks to its functional enhancements, the enhanced UM33A can handle both digital and analog communications with sensors, and is thus well positioned to facilitate the introduction of field digital solutions at plants.

Major Target Markets include companies that design and manufacture machinery, air conditioning systems, power equipment, tanks, and other items for use in industries, such as electrical equipment, machinery, chemicals, foods, semiconductors, and automobiles.
