Yokogawa has added two new models and increased the functionality of other units in its Green Series of digital indicating controllers. Typical applications include heat-treatment furnaces, incinerators, ovens and kilns in a variety of industries.
The UT420 and UT450, are general-purpose high-performance controllers with 5-digit displays, remote setpoint input, 1% measurement accuracy and simplified control functions for ease of configuration.
Enhancements to the whole Green Series include a new Super 2 function for suppressing hunting, Modbus communications interfaces, the provision of 24 V power supplies for transmitters, and enhanced custom computation capabilities for the top of the range UT/UP750 models.
All models in the range can now be programmed using a range of easy-to-use non-invasive programming tools known as the Light Loader Series. Running under Windows 95/98/NT, the LL100 parameter setting tool and LL200 custom computation building tool can set all relevant controller parameters via a simple graphic interface.
The controllers are provided with full CD-Rom based instructions as well as conventional paper manuals.
