【Support Information】List of RoHS

This is a list of recorder and controller products that support the RoHS (2011/65/EU) directive.


Taking advantage of sensors already available in your system, you can simply add VJ series signal conditioners or the UM33A Digital Indicator with Alarms to easily build a monitoring system on a PC.


Load devices are sometimes used when evaluating (measuring) DUT performance. Depending on the parameter being evaluated, multiple controllers can be employed to control the performance of the load device, but there are also times when the load device uses only one actuator. 


The MW100 can be used for measurement and monitoring at facilities that use solar heating and lighting.


DAQWORX Data Acquisition Software Suite helps the administrative department collect and monitor data on each section of the factory, including data on the usage of chemicals, gas, and electricity.


With advances in process automation comes a greater need for level measurement and control. As pressure on at the bottom surface of a liquid is proportional to the height of the liquid's surface, you can measure pressure using a differential pressure transmitter to detect the level of the liquid, acquire the data on the UT75A Digital Indicating Controller, and use the measurements to control the tank level.


HART communication is a means of transmitting multiple signals by superimposing long-standard 4-20 mA DC analog signals on digital signals. The figure below is an example of connecting field instruments and upstream devices using HART communication compatible VJA1/H signal conditioners.


With trends towards lowering power consumption, it has become commonplace to monitor the power consumed in offices and factories. Has it ever seemed that your office buildings and factories consume an inordinate amount of power? If so, there could be something wrong with the voltage or current of the power supply you are using, your building could be consuming too much standby power, or perhaps some equipment is being overloaded.


This introduces use of a contact input multiplication/addition computing unit that employs a user program of the MXT computing unit (XJJM.507) on fluid mixture and other calculated measurement outputs from flow meters. The figure below shows examples of connecting various field instruments to an upstream system.


In 1973 the ISA (Instrument Society of America) defined 4–20 mADC analog as the standarized signals for industrial measuring instruments, and they are still used today for transmission signals. The following are typical Yokogawa field instruments that utilize these 4–20 mADC transmission signals.


Even in the smaller scale, more diversified measuring systems that have appeared in recent years, engineers commonly need to monitor a scattering of instruments over large areas. The following is an example of using the communication functions of JUXTA VJ series signal conditioners to connect to our STARDOM network based production system.


Many signal conditioners have been used on the input and output sections of large-scale distributed control systems (DCSs) for isolation purposes. Recently personal computer-based instrumentation and measurement systems have become popular and brought with them significant functional enhancements.
