Data Loggers

For a data logger to monitor, test, and analyze asset health and performance, it records sensor data over long periods of time. Yokogawa data loggers surpass the scalability of standard data loggers by utilizing a proprietary block architecture that enables you to easily and flexibly combine various modules, and add expansion modules for up to 450 ch of input (GX/GP). They offer superior savings on rewiring labor and maintenance because you can add or remove modules even after installation.

>> Module groups corresponding for various Applications/Measurement targets.

Our data loggers are recognized in the industry for their outstanding measurement accuracy, reliability, noise resistance, and ease-of-use. They support US FDA 21 CFR Part11 (regulations on electronic records and electronic signatures), EU-GMP Annex11, and other associated guidelines for data management as required for development and manufacture in the pharmaceutical and foodstuff industries.
Data Loggers also support data integrity in accordance with ALCOA+. In addition, AMS2750E which is required for heat treatment in the aerospace industry is supported.

Caustic soda and hydrochloric acid, produced in electrolyzer plants, are fundamental materials used in varieties of industries; chemicals, pharmaceuticals, petrol-chemicals, pulp and papers, etc. Profit is the result of the effective production with minimized running / maintenance cost. Proper control of the process brings you stabilized quality of products with the vast operational profit.


The development of difficult to recover unconventional energy resources, is progressing. Figure 1 shows an example of how unconventional heavy oil is extracted from tar sand by reducing its viscosity with steam. To ensure efficient mining, changes in the underground temperature distribution will need to be monitored.
